The project of raising a railroad bridge while the line is still in service at Lewiston, Idaho was broken into five stages of construction. In addition to the raising of the bridge 9 ft 3 in., specifications include construction of two 11 41-ft concrete bridge piers and foundation reinforcement of one existing pier; replacement of two bridge spans, including one new lift span; and construction of an 8-ft wide 200-ft long shipping guide wall. Keys to the project are self-contained jacks.
