The West Broadway Tunnel Safety project will improve traffic 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 traffic safety improvements, such as reconfiguring roadway markings, signage, and improving traffic signals on Broadway between Polk and Powell streets. The project will maintain two traffic lanes in each direction.
Through the Neighborhood Transportation Program, the D3 Supervisors office has dedicated their funds to improving traffic and pedestrian safety in and near the Broadway tunnel. Specific improvements and project work include the following:
- Narrowing vehicle travel lanes via reconfiguring roadway striping,
- Installing a speed feedback radar sign at Broadway and Larkin,
- Adding playground warning signs and speed limit signs between Larkin and Polk,
- Upgrading the signal heads at Broadway and Larkin from an 8 inch to 12-inch size,
- Exploring potential turn calming at the intersection of Broadway and Larkin, and
- Adding bike parking within daylighting zones at Broadway and Polk.
A public comment card will be available for community members to provide their feedback on the project in July 2026.
