Contract 36 Traffic Signal Modifications

Project Introduction

The Contract 36 Traffic Signal Modifications project will implement traffic-signal related modifications at 14 locations across the City. Signal modifications include new pedestrian countdown signals (PCS), new accessible pedestrian signals (APS), new higher-visibility 12-inch traffic signals on mast arms, new left turn signals, curb ramps, and replacement of old/damaged signal infrastructure. Twelve of the intersections are located on the Vision Zero High Injury Network, which encompasses the pedestrian, bicycle, and vehicle high injury corridors. These signal modifications will improve accessibility and safety for all.

The project was made possible in part by Proposition K Sales Tax dollars provided by the San Francisco County Transportation Authority, General Fund Population Growth Proposition B funds, and a California Transportation Commission (CTC) Local Partnership Program (LPP) grant.
