Historic Bridges

Technical Assistance

FHWA assists in the preservation of historic bridges and encourages States to incorporate the concepts of context sensitive design in the rehabilitation and reuse of historic bridges. Programs for historic bridge preservation include:

• National Historic Covered Bridge Preservation Program provides funding to assist the States in their efforts to preserve, rehabilitate, or restore the Nation's historic covered bridges. Applications for the FY 2009 program were accepted until March 2, 2009, and awards will be announced in the summer. The criteria, associated selection considerations, and process for submission are at http://www.fhwa.dot.gov/bridge/nhcbp/090112.cfm.
  • In 2004, FHWA published a manual on covered bridge maintenance. Contact MaryAnn Naber or Sheila Duwadi to receive a free copy of the Covered Bridge Manual.
• Transportation Enhancements Program — The Transportation Enhancement Program provides funding and information that can help expand transportation choices, including rehabilitation of historic transportation facilities, scenic route improvements and other investments that increase recreation opportunity and access for communities.
• Highway Bridge Replacement and Rehabilitation Program — This Program includes a historic bridge provision that requires each State to complete historic bridge inventories and make attempts to market historic bridges slated for demolition. View information on the Interpretation of Title 23, Section 144(o) Reasonable Costs Associated With the Demolition of Historic Bridges.

Back to top State Bridge Programs 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.

This historic wrought iron bridge is known as a camel back bridge for its heavy concrete structure and smooth arches. This bridge has been preserved by moving it to a new location for it now to serve as a footbridge (Baraboo, WI).
