I-85 between Charlotte and Greensboro, NC, has long been one of the most congested corridors in the state, necessitating a massive reconstruction initiative. The joint venture of Flatiron-Lane was selected by the North Carolina Department of Transportation to lead the $136-million design-build contract to erect two bridges over the Yadkin River. The project was a key part of the larger I-85 Corridor Improvements program, which included upgrades to highway, bridge and rail infrastructure along the heavily trafficked section of I-85.
STV served as lead designer on the team, providing project management, bridge/structure design and railroad coordination. The completed dual bridges are 72 feet wide and 2,914 feet long, carrying eight lanes that spans a wetland, the river and three railroad tracks. The award-winning bridge received numerous accolades, including the Grand Award from the American Council of Engineering Companies of North Carolina, the National Merit Award from the Design-Build Institute of America, and it was named a Top 10 Bridge and Road by Roads & Bridges magazine.
