OT: Alemany Interchange Improvement Study

[Chris Waddling]

The Alemany Interchange Improvement Study was recommended by former Commissioner Campos for $100,000 in Prop K sales tax funds from the Transportation Authority’s Neighborhood Transportation Improvement Program (NTIP). This community-driven project addresses concerns about safety and access across and along Alemany Boulevard between Bayshore Boulevard and Putnam Street, which provides access to Alemany Farmers Market. This portion of Alemany, where U.S. 101, I-280, San Bruno Avenue and Bayshore Boulevard intersect, presents major challenges to pedestrian and bicycle safety and accessibility. The freeways and vehicle-oriented street design present barriers between the surrounding neighborhoods and limit crossing opportunities, requiring pedestrians, bicyclists, and transit riders to navigate a circuitous maze of high-speed streets and ramps. The Study has identified two phases for improvements through this corridor. 

Phase 1 recommendations include: extend the existing Alemany bicycle lanes from west of Putnam to connect to existing bicycle lanes on Bayshore Boulevard; reduce Alemany vehicle lanes from three to two in each direction; and restripe for multimodal improvements and traffic calming at intersections. Phase 2 recommendations include: a new multiuse path connecting from San Bruno Avenue to the Alemany Farmers Market, with a new traffic signal and marked crosswalk to facilitate pedestrian crossing of westbound Alemany. Phase 1 is funded with NTIP Capital funds and scheduled to be completed by mid-2018. The first step of Phase 2 is funded with $100,000 from the General Fund. This step would include a project location survey and preliminary path design. Throughout the project, we collaborated with various community groups including Portola Neighborhood Association, SF Empowerment Center, and Portola Family Connection.
