According to American Cranes & Transport, Cascade Bridge and Mountain Crane are completing lifts for a bridge project over the Snake River just west of Ashton, Idaho. The project includes installation of new precast concrete girders downstream of the current bridge, followed by removal of the existing bridge.

Ryan and Chandler Bingham, the father-son duo behind Mountain Crane’s Idaho division, were tasked with setting 20 precast concrete girders that were 105 feet long and weighed 90,000 pounds. With four spans, all girders were set from a construction bridge. Each girder was set in place by the two Link-Belt lattice crawler cranes, a 300-ton 348 H5 crawler and a 110-ton 218 HSL crawler.

Using the retracted sideframe chart for the Link-Belt 348 H5 left crews with two inches of deck space on each side. Bingham said the toughest pick was the first bridge span to the west. The Mountain team had to carefully weave the precast girder between both machines.
