CHAPTER XI.

TELFORD AS A ROAD-MAKER.

Mr. Telford's extensive practice as a bridge-builder led his friend

Southey to designate him "Pontifex Maximus." Besides the numerous

bridges erected by him in the West of England, we have found him

furnishing designs for about twelve hundred in the Highlands, of

various dimensions, some of stone and others of iron. His practice

in bridge-building had, therefore, been of an unusually extensive

character, and Southey's sobriquet was not ill applied. But besides

being a great bridge-builder, Telford was also a great road-maker.

With the progress of industry and trade, the easy and rapid transit

of persons and goods had come to be regarded as an increasing

object of public interest. Fast coaches now ran regularly between

all the principal towns of England; every effort being made,

by straightening and shortening the roads, cutting down hills,

and carrying embankments across valleys and viaducts over rivers,

to render travelling by the main routes as easy and expeditious as

possible.

Attention was especially turned to the improvement of the longer

routes, and to perfecting the connection of London with the chief

town's of Scotland and Ireland. Telford was early called upon to

advise as to the repairs of the road between Carlisle and Glasgow,

which had been allowed to fall into a wretched state; as well as

the formation of a new line from Carlisle, across the counties of

Dumfries, Kirkcudbright, and Wigton, to Port Patrick, for the

purpose of ensuring a more rapid communication with Belfast and the

northern parts of Ireland. Although Glasgow had become a place of

considerable wealth and importance, the roads to it, north of

Carlisle, continued in a very unsatisfactory state. It was only in

July, 1788, that the first mail-coach from London had driven into

Glasgow by that route, when it was welcomed by a procession of the

citizens on horseback, who went out several miles to meet it.

But the road had been shockingly made, and before long had become

almost impassable. Robert Owen states that, in 1795, it took him

two days and three nights' incessant travelling to get from

Manchester to Glasgow, and he mentions that the coach had to cross

a well-known dangerous mountain at midnight, called Erickstane

Brae, which was then always passed with fear and trembling.*[1]

As late as the year 1814 we find a Parliamentary Committee

declaring the road between Carlisle and Glasgow to be in so ruinous

a state as often seriously to delay the mail and endanger the lives

of travellers. The bridge over Evan Water was so much decayed, that

one day the coach and horses fell through it into the river, when

"one passenger was killed, the coachman survived only a few days,

and several other persons were dreadfully maimed; two of the horses

being also killed."*[2] The remaining part of the bridge continued

for some time unrepaired, just space enough being left for a single

carriage to pass. The road trustees seemed to be helpless, and did

nothing; a local subscription was tried and failed, the district

passed through being very poor; but as the road was absolutely

required for more than merely local purposes, it was eventually

determined to undertake its reconstruction as a work of national

importance, and 50,000L. was granted by Parliament with this

object, under the provisions of the Act passed in 1816. The works

were placed under Mr. Telford's charge; and an admirable road was

very shortly under construction between Carlisle and Glasgow.

That part of it between Hamilton and Glasgow, eleven miles in length,

was however left in the hands of local trustees, as was the

diversion of thirteen miles at the boundary of the counties of

Lanark and Dumfries, for which a previous Act had been obtained.

The length of new line constructed by Mr. Telford was sixty-nine

miles, and it was probably the finest piece of road which up to

that time had been made.

His ordinary method of road-making in the Highlands was, first to

level and drain; then, like the Romans, to lay a solid pavement of

large stones, the round or broad end downwards, as close as they

could be set. The points of the latter were then broken off, and a

layer of stones broken to about the size of walnuts, was laid upon

them, and over all a little gravel if at hand. A road thus formed

soon became bound together, and for ordinary purposes was very

durable.

But where the traffic, as in the case of the Carlisle and Glasgow

road, was expected to be very heavy, Telford took much greater

pains. Here he paid especial attention to two points: first, to lay

it out as nearly as possible upon a level, so as to reduce the

draught to horses dragging heavy vehicles,--one in thirty being

about the severest gradient at any part of the road. The next point

was to make the working, or middle portion of the road, as firm and

substantial as possible, so as to bear, without shrinking, the

heaviest weight likely to be brought over it. With this object he

specified that the metal bed was to be formed in two layers, rising

about four inches towards the centre the bottom course being of

stones (whinstone, limestone, or hard freestone), seven inches in

depth. These were to be carefully set by hand, with the broadest

ends downwards, all crossbonded or jointed, no stone being more

than three inches wide on the top. The spaces between them were

then to be filled up with smaller stones, packed by hand, so as to

bring the whole to an even and firm surface. Over this a top course

was to be laid, seven inches in depth, consisting of properly

broken hard whinstones, none exceeding six ounces in weight, and

each to be able to pass through a circular ring, two inches and a

half in diameter; a binding of gravel, about an inch in thickness,

being placed over all. A drain crossed under the bed of the bottom

layer to the outside ditch in every hundred yards. The result was

an admirably easy, firm, and dry road, capable of being travelled

upon in all weathers, and standing in comparatively small need of

repairs.

A similar practice was introduced in England about the same time by

Mr. Macadam; and, though his method was not so thorough as that of

Telford, it was usefully employed on most of the high roads

throughout the kingdom. Mr. Macadam's notice was first called to

the subject while acting as one of the trustees of a road in

Ayrshire. Afterwards, while employed as Government agent for

victualling the navy in the western parts of England, he continued

the study of road-making, keeping in view the essential conditions

of a compact and durable substance and a smooth surface. At that

time the attention of the Legislature was not so much directed to

the proper making and mending of the roads, as to suiting the

vehicles to them such as they were; and they legislated backwards

and forwards for nearly half a century as to the breadth of wheels.

Macadam was, on the other hand, of opinion that the main point was

to attend to the nature of the roads on which the vehicles were to

travel. Most roads were then made with gravel, or flints tumbled

upon them in their natural state, and so rounded that they had no

points of contact, and rarely became consolidated. When a heavy

vehicle of any sort passed over them, their loose structure

presented no resistance; the material was thus completely

disturbed, and they often became almost impassable. Macadam's

practice was this: to break the stones into angular fragments, so

that a bed several inches in depth should be formed, the material

best adapted for the purpose being fragments of granite,

greenstone, or basalt; to watch the repairs of the road carefully

during the process of consolidation, filling up the inequalities

caused by the traffic passing over it, until a hard and level

surface had been obtained. Thus made, the road would last for

years without further attention. in 1815 Mr. Macadam devoted

himself with great enthusiasm to road-making as a profession, and

being appointed surveyor-general of the Bristol roads, he had full

opportunities of exemplifying his system. It proved so successful

that the example set by him was quickly followed over the entire

kingdom. Even the streets of many large towns were Macadamised.

In carrying out his improvements, however, Mr. Macadam spent several

thousand pounds of his own money, and in 1825, having proved this

expenditure before a Committee of the House of Commons, the amount

was reimbursed to him, together with an honorary tribute of two

thousand pounds. Mr. Macadam died poor, but, as he himself said,

"a least an honest man." By his indefatigable exertions and his

success as a road-maker, by greatly saving animal labour,

facilitating commercial intercourse, and rendering travelling easy

and expeditious, he entitled himself to the reputation of a public

benefactor.

Owing to the mountainous nature of the country through which

Telford's Carlisle and Glasgow road passes, the bridges are

unusually numerous and of large dimensions. Thus, the Fiddler's

Burn Bridge is of three arches, one of 150 and two of 105 feet span

each. There are fourteen other bridges, presenting from one to

three arches, of from 20 to 90 feet span. But the most picturesque

and remarkable bridge constructed by Telford in that district was

upon another line of road subsequently carried out by him, in the

upper part of the county of Lanark, and crossing the main line of

the Carlisle and Glasgow road almost at right angles. Its northern

and eastern part formed a direct line of communication between the

great cattle markets of Falkirk, Crief, and Doune, and Carlisle and

the West of England. It was carried over deep ravines by several

lofty bridges, the most formidable of which was that across the

Mouse Water at Cartland Crags, about a mile to the west of Lanark.

The stream here flows through a deep rocky chasm, the sides of

which are in some places about four hundred feet high. At a point

where the height of the rocks is considerably less, but still most

formidable, Telford spanned the ravine with the beautiful bridge

represented in the engraving facing this page, its parapet being

129 feet above the surface of the water beneath.

[Image] Cartland Crags Bridge.

The reconstruction of the western road from Carlisle to Glasgow,

which Telford had thus satisfactorily carried out, shortly led to

similar demands from the population on the eastern side of the

kingdom. The spirit of road reform was now fairly on foot.

Fast coaches and wheel-carriages of all kinds had become greatly

improved, so that the usual rate of travelling had advanced from

five or six to nine or ten miles an hour. The desire for the rapid

communication of political and commercial intelligence was found to

increase with the facilities for supplying it; and, urged by the

public wants, the Post-Office authorities were stimulated to

unusual efforts in this direction. Numerous surveys were made and

roads laid out, so as to improve the main line of communication

between London and Edinburgh and the intermediate towns. The first

part of this road taken in hand was the worst--that lying to the

north of Catterick Bridge, in Yorkshire. A new line was surveyed by

West Auckland to Hexham, passing over Garter Fell to Jedburgh, and

thence to Edinburgh; but was rejected as too crooked and uneven.

Another was tried by Aldstone Moor and Bewcastle, and rejected for

the same reason. The third line proposed was eventually adopted as

the best, passing from Morpeth, by Wooler and Coldstream,

to Edinburgh; saving rather more than fourteen miles between the

two points, and securing a line of road of much more favourable

gradients.

The principal bridge on this new highway was at Pathhead, over the

Tyne, about eleven miles south of Edinburgh. To maintain the

level, so as to avoid the winding of the road down a steep descent

on one side of the valley and up an equally steep ascent on the

other, Telford ran out a lofty embankment from both sides,

connecting their ends by means of a spacious bridge. The structure

at Pathhead is of five arches, each 50 feet span, with 25 feet rise

from their springing, 49 feet above the bed of the river. Bridges

of a similar character were also thrown over the deep ravines of

Cranston Dean and Cotty Burn, in the same neighbourhood. At the

same time a useful bridge was built on the same line of road at

Morpeth, in Northumberland, over the river Wansbeck. It consisted

of three arches, of which the centre one was 50 feet span, and two

side-arches 40 feet each; the breadth between the parapets being 30

feet.

The advantages derived from the construction of these new roads

were found to be so great, that it was proposed to do the like for

the remainder of the line between London and Edinburgh; and at the

instance of the Post-Office authorities, with the sanction of the

Treasury, Mr. Telford proceeded to make detailed surveys of an

entire new post-road between London and Morpeth. In laying it out,

the main points which he endeavoured to secure were directness and

flatness; and 100 miles of the proposed new Great North Road, south

of York, were laid out in a perfectly straight line. This survey,

which was begun in 1824, extended over several years; and all the

requisite arrangements had been made for beginning the works, when

the result of the locomotive competition at Rainhill, in 1829, had

the effect of directing attention to that new method of travelling,

fortunately in time to prevent what would have proved, for the most

part, an unnecessary expenditure, on works soon to be superseded by

a totally different order of things.

The most important road-improvements actually carried out under

Mr. Telford's immediate superintendence were those on the western

side of the island, with the object of shortening the distance and

facilitating the communication between London and Dublin by way of

Holyhead, as well as between London and Liverpool. At the time of

the Union, the mode of transit between the capital of Ireland and

the metropolis of the United Kingdom was tedious, difficult, and

full of peril. In crossing the Irish Sea to Liverpool, the packets

were frequently tossed about for days together. On the Irish side,

there was scarcely the pretence of a port, the landing-place being

within the bar of the river Liffey, inconvenient at all times, and

in rough weather extremely dangerous. To avoid the long voyage to

Liverpool, the passage began to be made from Dublin to Holyhead,

the nearest point of the Welsh coast. Arrived there, the

passengers were landed upon rugged, unprotected rocks, without a

pier or landing convenience of any kind.*[3] But the traveller's

perils were not at an end,--comparatively speaking they had only

begun. From Holyhead, across the island of Anglesea, there was no

made road, but only a miserable track, circuitous and craggy,

full of terrible jolts, round bogs and over rocks, for a distance of

twenty-four miles. Having reached the Menai Strait, the passengers

had again to take to an open ferry-boat before they could gain the

mainland. The tide ran with great rapidity through the Strait,

and, when the wind blew strong, the boat was liable to be driven

far up or down the channel, and was sometimes swamped altogether.

The perils of the Welsh roads had next to be encountered, and these

were in as bad a condition at the beginning of the present century

as those of the Highlands above described. Through North Wales

they were rough, narrow, steep, and unprotected, mostly unfenced,

and in winter almost impassable. The whole traffic on the road

between Shrewsbury and Bangor was conveyed by a small cart, which

passed between the two places once a week in summer. As an

illustration of the state of the roads in South Wales, which were

quite as bad as those in the North, we may state that, in 1803,

when the late Lord Sudeley took home his bride from the

neighbourhood of Welshpool to his residence only thirteen miles

distant, the carriage in which the newly married pair rode stuck in

a quagmire, and the occupants, having extricated themselves from

their perilous situation, performed the rest of their journey on

foot.

The first step taken was to improve the landing-places on both the

Irish and Welsh sides of St. George's Channel, and for this purpose

Mr. Rennie was employed in 1801. The result was, that Howth on the

one coast, and Holyhead on the other, were fixed upon as the most

eligible sites for packet stations. Improvements, however,

proceeded slowly, and it was not until 1810 that a sum of 10,000L.

was granted by Parliament to enable the necessary works to be

begun. Attention was then turned to the state of the roads,

and here Mr. Telford's services were called into requisition.

As early as 1808 it had been determined by the Post-Office authorities

to put on a mail-coach between Shrewsbury and Holyhead; but it was

pointed out that the roads in North Wales were so rough and

dangerous that it was doubtful whether the service could be

conducted with safety. Attempts were made to enforce the law with

reference to their repair, and no less than twenty-one townships

were indicted by the Postmaster-General. The route was found too

perilous even for a riding post, the legs of three horses having

been broken in one week.*[4] The road across Anglesea was quite as

bad. Sir Henry Parnell mentioned, in 1819, that the coach had been

overturned beyond Gwynder, going down one of the hills, when a

friend of his was thrown a considerable distance from the roof into

a pool of water. Near the post-office of Gwynder, the coachman had

been thrown from his seat by a violent jolt, and broken his leg.

The post-coach, and also the mail, had been overturned at the

bottom of Penmyndd Hill; and the route was so dangerous that the

London coachmen, who had been brought down to "work" the country,

refused to continue the duty because of its excessive dangers.

Of course, anything like a regular mail-service through such a

district was altogether impracticable.

The indictments of the townships proved of no use; the localities

were too poor to provide the means required to construct a line of

road sufficient for the conveyance of mails and passengers between

England and Ireland. The work was really a national one, to be

carried out at the national cost. How was this best to be done?

Telford recommended that the old road between Shrewsbury and

Holyhead (109 miles long) should be shortened by about four miles,

and made as nearly as possible on a level; the new line proceeding

from Shrewsbury by Llangollen, Corwen, Bettws-y-Coed, Capel-Curig,

and Bangor, to Holyhead. Mr. Telford also proposed to cross the

Menai Strait by means of a cast iron bridge, hereafter to be

described.

Although a complete survey was made in 1811, nothing was done for

several years. The mail-coaches continued to be overturned, and

stage-coaches, in the tourist season, to break down as before.*[5]

The Irish mail-coach took forty one hours to reach Holyhead from

the time of its setting out from St. Martin's-le-Grand; the journey

was performed at the rate of only 6 3/4 miles an hour, the mail

arriving in Dublin on the third day. The Irish members made many

complaints of the delay and dangers to which they were exposed in

travelling up to town. But, although there was much discussion, no

money was voted until the year 1815, when Sir Henry Parnell

vigorously took the question in hand and successfully carried it

through. A Board of Parliamentary Commissioners was appointed, of

which he was chairman, and, under their direction, the new

Shrewsbury and Holyhead road was at length commenced and carried to

completion, the works extending over a period of about fifteen years.

The same Commissioners excrcised an authority over the roads

between London and Shrewsbury; and numerous improvements were also

made in the main line at various points, with the object of

facilitating communication between London and Liverpool as well as

between London and Dublin.

The rugged nature of the country through which the new road passed,

along the slopes of rocky precipices and across inlets of the sea,

rendered it necessary to build many bridges, to form many

embankments, and cut away long stretches of rock, in order to

secure an easy and commodious route. The line of the valley of the

Dee, to the west of Llangollen, was selected, the road proceeding

along the scarped sides of the mountains, crossing from point to

point by lofty embankments where necessary; and, taking into

account the character of the country, it must be acknowledged that

a wonderfully level road was secured. While the gradients on the

old road had in some cases been as steep as 1 in 6 1/2, passing

along the edge of unprotected precipices, the new one was so laid

out as to be no more than 1 in 20 at any part, while it was wide

and well protected along its whole extent. Mr. Telford pursued the

same system that he had adopted in the formation of the Carlisle

and Glasgow road, as regards metalling, cross-draining, and

fence-walling; for the latter purpose using schistus, or slate

rubble-work, instead of sandstone. The largest bridges were of

iron; that at Bettws-y-Coed, over the Conway--called the Waterloo

Bridge, constructed in 1815--being a very fine specimen of

Telford's iron bridge-work.

Those parts of the road which had been the most dangerous were

taken in hand first, and, by the year 1819, the route had been

rendered comparatively commodious and safe. Angles were cut off,

the sides of hills were blasted away, and several heavy embankments

run out across formidable arms of the sea. Thus, at Stanley Sands,

near Holyhead, an embankment was formed 1300 yards long and 16 feet

high, with a width of 34 feet at the top, along which the road was

laid. Its breadth at the base was 114 feet, and both sides were

coated with rubble stones, as a protection against storms. By the

adoption of this expedient, a mile and a half was saved in a

distance of six miles. Heavy embankments were also run out, where

bridges were thrown across chasms and ravines, to maintain the

general level. From Ty-Gwynn to Lake Ogwen, the road along the face

of the rugged hill and across the river Ogwen was entirely new

made, of a uniform width of 28 feet between the parapets, with an

inclination of only 1 in 22 in the steepest place. A bridge was

thrown over the deep chasm forming the channel of the Ogwen, the

embankment being carried forward from the rook cutting, protected

by high breastworks. From Capel-Curig to near the great waterfall

over the river Lugwy, about a mile of new road was cut; and a still

greater length from Bettws across the river Conway and along the

face of Dinas Hill to Rhyddlanfair, a distance of 3 miles; its

steepest descent being 1 in 22, diminishing to 1 in 45. By this

improvement, the most difficult and dangerous pass along the route

through North Wales was rendered safe and commodious.

[Image] Road Descent near Betws-y-Coed.

Another point of almost equal difficulty occurred near Ty-Nant,

through the rocky pass of Glynn Duffrws, where the road was

confined between steep rocks and rugged precipices: there the way

was widened and flattened by blasting, and thus reduced to the

general level; and so on eastward to Llangollen and Chirk, where

the main Shrewsbury road to London was joined.*[6]

[Image] Road above Nant Frrancon, North Wales.

By means of these admirable roads the traffic of North Wales

continues to be mainly carried on to this day. Although railways

have superseded coach-roads in the more level districts, the hilly

nature of Wales precludes their formation in that quarter to any

considerable extent; and even in the event of railways being

constructed, a large part of the traffic of every country must

necessarily continue to pass over the old high roads. Without them

even railways would be of comparatively little value; for a railway

station is of use chiefly because of its easy accessibility, and

thus, both for passengers and merchandise, the common roads of the

country are as useful as ever they were, though the main post-roads

have in a great measure ceased to be employed for the purposes for

which they were originally designed.

The excellence of the roads constructed by Mr. Telford through the

formerly inaccessible counties of North Wales was the theme of

general praise; and their superiority, compared with those of the

richer and more level districts in the midland and western English

counties, becoming the subject of public comment, he was called

upon to execute like improvements upon that part of the post-road

which extended between Shrewsbury and the metropolis. A careful

survey was made of the several routes from London northward by

Shrewsbury as far as Liverpool; and the short line by Coventry,

being 153 miles from London to Shrewsbury, was selected as the one

to be improved to the utmost.

Down to 1819, the road between London and Coventry was in a very

bad state, being so laid as to become a heavy slough in wet

weather. There were many steep hills which required to be cut down,

in some parts of deep clay, in others of deep sand. A mail-coach

had been tried to Banbury; but the road below Aylesbury was so bad,

that the Post-office authorities were obliged to give it up. The

twelve miles from Towcester to Daventry were still worse. The line

of way was covered with banks of dirt; in winter it was a puddle of

from four to six inches deep--quite as bad as it had been in Arthur

Young's time; and when horses passed along the road, they came out

of it a mass of mud and mire.*[7] There were also several steep and

dangerous hills to be crossed; and the loss of horses by fatigue in

travelling by that route at the time was very great.

Even the roads in the immediate neighbourhood of the metropolis

were little better, those under the Highgate and Hampstead trust

being pronounced in a wretched state. They were badly formed,

on a clay bottom, and being undrained, were almost always wet and

sloppy. The gravel was usually tumbled on and spread unbroken,

so that the materials, instead of becoming consolidated, were only

rolled about by the wheels of the carriages passing over them.

Mr. Telford applied the same methods in the reconstruction of these

roads that he had already adopted in Scotland and Wales, and the

same improvement was shortly felt in the more easy passage over

them of vehicles of all sorts, and in the great acceleration of the

mail service. At the same time, the line along the coast from

Bangor, by Conway, Abergele, St. Asaph, and Holywell, to Chester,

was greatly improved. As forming the mail road from Dublin to

Liverpool, it was considered of importance to render it as safe

and level as possible. The principal new cuts on this line were

those along the rugged skirts of the huge Penmaen-Mawr; around the

base of Penmaen-Bach to the town of Conway; and between St. Asaph

and Holywell, to ease the ascent of Rhyall Hill.

But more important than all, as a means of completing the main line

of communication between England and Ireland, there were the great

bridges over the Conway and the Menai Straits to be constructed.

The dangerous ferries at those places had still to be crossed in

open boats, sometimes in the night, when the luggage and mails were

exposed to great risks. Sometimes, indeed, they were wholly lost

and passengers were lost with them. It was therefore determined,

after long consideration, to erect bridges over these formidable

straits, and Mr. Telford was employed to execute the works,--in

what manner, we propose to describe in the next chapter.

are a number of dangerous precipices without fences, exclusive of

various hills that want taking down. At Ogwen Pool there is a very

dangerous place where the water runs over the road, extremely

difficult to pass at flooded times. Then there is Dinas Hill, that

needs a side fence against a deep precipice. The width of the road

is not above twelve feet in the steepest part of the hill, and two

carriages cannot pass without the greatest danger. Between this

hill and Rhyddlanfair there are a number of dangerous precipices,

steep hills, and difficult narrow turnings. From Corwen to

Llangollen the road is very narrow, long, and steep; has no side

fence, except about a foot and a half of mould or dirt, which is

thrown up to prevent carriages falling down three or four hundred

feet into the river Dee. Stage-coaches have been frequently

overturned and broken down from the badness of the road, and the

mails have been overturned; but I wonder that more and worse

accidents have not happened, the roads are so bad."--Evidence of

*[6] The Select Committee of the House of Commons, in reporting as

to the manner in which these works were carried out, stated as

follows:-- "The professional execution of the new works upon this

road greatly surpasses anything of the same kind in these

countries. The science which has been displayed in giving the

general line of the road a proper inclination through a country

whose whole surface consists of a succession of rocks, bogs,

ravines, rivers, and precipices, reflects the greatest credit upon

the engineer who has planned them; but perhaps a still greater

degree of professional skill has been shown in the construction, or

rather the building, of the road itself. The great attention which

Mr. Telford has devoted, to give to the surface of the road one

uniform and moderately convex shape, free from the smallest

inequality throughout its whole breadth; the numerous land drains,

and, when necessary, shores and tunnels of substantial masonry,

with which all the water arising from springs or falling in rain is

instantly carried off; the great care with which a sufficient

foundation is established for the road, and the quality, solidity,

and disposition of the materials that are put upon it, are matters

quite new in the system of road-making in these countries."--
