There are many intersections in San Francisco’s South of Market neighborhood where freeway on- or off-ramps intersect city streets. Many of these ramps are located close to public schools, single room occupancy hotels, and senior centers, which are frequented by populations at high risk of injury from traffic collisions.
The Transportation Authority has been studying how to improve safety at 15 of these intersections with support from Caltrans and the SFMTA. The goal of these studies is to improve safety for all travelers, especially the most vulnerable populations, and to support progress towards the City's Vision Zero goal to eliminate traffic fatalities by 2024.
The area in the South of Market neighborhood designated as a Youth and Family Zone includes multiple locations where freeway on- or off-ramps intersect city streets. These ramp intersections tend to have particularly high frequencies of traffic injuries and fatalities. The Transportation Authority and the SFMTA developed recommendations for improving safety at five ramp intersections within this zone. The Transportation Authority Board adopted the study Final Report in May 2018.
The Transportation Authority has received Caltrans grant funding to evaluate 10 additional ramp intersections within the greater South of Market neighborhood, building from the first study. The Transportation Authority and SFMTA are currently studying the additional intersections and will develop recommendations for improving safety at at these intersections as well.
Freeway ramp intersections in SoMa
There are 22 intersections in SoMa where freeway on- or off-ramps intersect city streets. This map shows all of the projects and plans that are underway at these intersections. The Transportation Authority is working to improve safety at 15 of these intersections through the studies outlined above.
