Goble Grading Section
A new location of the Columbia River Highway was made from a point two miles east of Goble to Goble Creek and a new concrete bridge built over Goble Creek, making a saving in distance of about one-half mile and doing away with several excessive grades, sharp curves and narrow roadbed, also a dangerous bridge and trestle across Goble Creek.
A rock cut between Goble and Goble Creek was taken out by the S. P. & S. Ry. Co. with steam shovels and the material used by them for riprap, thus making a considerable saving to the State Highway Commission. The material for the west approach to the new bridge was obtained by blasting and barring down rock from a dangerous perpendicular cliff about 1,000 feet west of the bridge, from which large rocks had fallen onto the highway. To make the highway safe it was necessary to remove this material and by using it in the bridge approach, did away with other borrow which would have been necessary. The cliff is about 200 feet high with the highway and S. P. & S. Ry. side by side at the foot, necessitating very light shots and careful work and was completed without accident to men or interruption of traffic on the railroad.
