Synthesis of Information Related to Highway Practices. Topic 53-12. Practices for Adding Bicycle and Pedestrians Access on Existing Vehicle Bridges

Many state departments of transportation (DOTs) have created plans for improving or expanding existing bicycle/pedestrian networks to increase active transportation options along their state-owned roadways. Expanding these networks on roadways might be accomplished by reallocating roadway space to dedicate space or by constructing new facilities to safely accommodate active transportation users. However, since many vehicle bridges were not originally designed for active transportation users (e.g., no sidewalks or shoulders), they represent one source of gaps in existing and potential active transportation networks. Closing these gaps across an existing vehicle bridge is a common problem for state DOTs with no “one size fits all” solution. The objective of this synthesis is to document the practices employed by state DOTs to provide or improve access to existing vehicle bridges for active transportation users. The synthesis will only focus on existing vehicle bridges and not on new construction.
