West Broadway Tunnel Safety

Introduction

The West Broadway Tunnel Safety project will improve safety and slow traffic speeds at the west end of the Robert C. Levy (Broadway) Tunnel. The project will design and implement a series of safety improvements, including roadway markings, signage, and traffic signals, on Broadway between Polk and Powell streets, while maintaining two lanes in each direction. The project also includes bike corrals at Broadway and Polk streets.

The project aims to address vehicle speeds and pedestrian safety concerns. Specific improvements include the following:

• Restripe vehicle traffic lanes to a narrower width to encourage lower vehicle speeds while maintaining two traffic lanes in each direction.
• Install a speed feedback radar sign facing westbound traffic at Larkin Street to increase awareness of vehicle speeds. There is a similar sign currently posted at Powell Street facing eastbound traffic.
• Add PLAYGROUND warning signs and speed limit signs between Polk Street and Larkin Street.
• Upgrade the traffic signals at the intersection of Broadway and Larkin Street with larger, more visible lenses and adjust the timing to slow the progression of traffic entering the tunnel.
• Add bike parking at Broadway and Polk Street, and turn calming at Broadway and Larkin Street.

Community outreach will be conducted in partnership with the District 3 Supervisor’s office. Additional outreach to the community will be performed by SFMTA staff during the design and construction phases through online surveys and informational mailers.

The Transportation Authority’s Neighborhood Program is intended to strengthen project pipelines and advance the delivery of community supported neighborhood-scale projects, especially in Equity Priority Communities and other neighborhoods with high unmet needs.
