Featured Steel Bridge Project

Lake Bridges Over Kentucky Lake and Lake Barkley
Opened to traffic in 2018, the new U.S. 68/KY 80 Bridges replaced two narrow 20-foot-wide 1930's era truss bridges. The main spans over each of the navigable waterways with substantial barge traffic feature a unique, basket-handled tied arch superstructure with steel plate girder approaches.

Homestead Grays Bridge--a high-level steel bridge nearly 100 feet above the Monongahela River.
