State Bridge Programs
The Humpback Covered Bridge was built in 1857 for the old James River and Kanawha Turnpike Company. The center of the floor and roof is about four feet higher than at the ends. It is the only bridge of its design in the United States.
Many State DOTs have developed historic bridge programs. These programs aim to preserve the historic and cultural value of long-standing bridges where possible and expedite the consideration of historic bridges in project development and environmental review. For example, Indiana's Historic Bridge Program helps planners prioritize a list of bridges for preservation, while providing bridge owners incentives for this preservation.
