During 1917 and 1918 the State Highway Department made a location survey
over the entire east and west route across Umatilla County, excepting
the six mile section between Pendleton and the Indian Agency. On this
six miles a base line survey only was made.
The section of this road between the Morrow County Line and Pendleton is
a part of the Columbia River Highway and has a total length of 40.5
miles. It passes through Umatilla, Hermiston, Stanfield, Echo and Reith.
From Pendleton east the road is known as the Old Oregon Trail.
The survey in the east end of the County begins at the Umatilla Indian
Agency, follows the general direction of the present road up Cabbage
Hill, passes through Meacham and ends at the Union County Line near
Kamela. A five per cent grade was secured on the Cabbage Hill climb. The
total length of this section is 26.8 miles. R. H. Baldock and Oscar
Cutler were the locating engineers on this work. The plans for this
survey are practically complete.
