Virginia's Tallest Segmental Box Bridge Under Construction

摘要

Phase I of the U.S. 460 Connector project in Breaks, Va., is under way and scheduled for completion in the summer of 2014. Bizzack Construction LLC is the general contractor. CJ Mahan Construction Co. has teamed up with VSL and Doka USA to provide the formwork and traveler system on this design-build project. "This will be the tallest bridge in Virginia when it's complete," says Todd Solar, senior account manager with Doka. The $113-million, balanced-cantilever concrete bridge will be 1,733 ft long and 250 ft tall. The project includes 15,340 sq ft of pre-assembled Top 50 formwork that builds four sets of traveler forms. The segmental boxes vary in depth from 31 ft at the pier table to 12 ft, 6 in. at the mid-span of the bridge.
