• Complete the Bicycle and Pedestrian Network– Create a Consistent Cross Section– Fill in Gaps and Connect to Activity

Centers/Neighborhoods– Restore Deteriorated Paths

Bicycle / Pedestrian Accommodations




49

• Relocate Bus Stops– Locate Bus Stops with Safe Road Crossings (e.g., at

signalized crossings, pedestrian overpasses/underpasses)– Comply with County Transit Plans– Promote consistency in bus stop locations





50

• Enhance Pedestrian Crossings– At-Grade Crossings at Signalized Intersections


Braddock Road at Burke Lake Road
