Curb extensions are particularly valuable in locations with high volumes of pedestrian traffic, near schools, at unsignalized pedestrian crossings, or where there are demonstrated pedestrian safety issues. Curb extensions shorten crossing distances and make people walking more visible to drivers, thereby improving pedestrian safety. Where is the City of Alexandria implementing curb extensions? As part of the City of Alexandria’s Safe Routes to School program, Walk Audits were conducted for all Alexandria elementary schools. Curb extensions were recommended at many nearby intersections to improve safety for students and their families when crossing the street.

Curb extensions are currently planned for the following locations and will be installed in 2018:
