Many bridges are built without accommodations for active transportation users and only serve motorized traffic. The pedestrians and bicyclists who rely on these bridges are exposed to safety-related concerns and their access to equal employment opportunities and essential services may be hindered.
The TRB National Cooperative Highway Research Program's NCHRP Synthesis 604: Practices for Adding Bicycle and Pedestrian Access on Existing Vehicle Bridges documents the practices employed by state departments of transportation to provide or improve access to existing vehicle bridges for active transportation users.
