We give illustrations from _Engineering_ of a bridge recently constructed
across the Indus River at Attock, for the Punjaub Northern State Railway.
This bridge, which was opened on May 24, 1883, was erected under the
direction of Mr. F.L. O'Callaghan, engineer in chief, Mr. H. Johnson
acting as executive engineer, and Messrs. R.W. Egerton and H. Savary as
assistants.

STATE RAILWAY, INDIA.]
The principal spans cover a length of about 1,150 feet. It will be seen
from the diagram that there is a difference of nearly 100 feet in the
levels of high and low water.
