The project proposes to depress the intersection of Rengstorff Avenue and Central Expressway to enhance safety, traffic flow, railroad operational safety and traffic movement along adjacent streets and intersections. The proposed project includes the following features: Leland Connector to maintain vehicle access to La Plaza Market, an Americans with Disabilities Act-compliant pathway to provide access between Crisanto Avenue and Rengstorff Avenue, a bicycle/pedestrian overcrossing to maintain east-west connection across Rengstorff Avenue, and the elevated train tracks to completely separate the train from vehicle, pedestrian and bicycle traffic on Rengstorff Avenue.

The figure below illustrates the following project elements:

A lowered intersection of Rengstorff Avenue and Central Expressway
A structure for the Caltrain tracks at approximate existing elevation
A bicycle and pedestrian bridge to maintain east-west connection between Leland Avenue and Crisanto Avenue on Rengstorff Avenue
Stairs on both sides of the bicycle and pedestrian bridge
Leland Connector to maintain access to the residential and area and market on the west side of Rengstorff Avenue
An American with Disabilities Act (ADA)-compliant pathway from Crisanto Avenue to the lowered Rengstorff Avenue
A parking lot for La Plaza Market with the same number of parking spaces at approximately the same location
Buffered bike lanes along Rengstorff Avenue within the project limits
Widened crosswalks and pedestrian refuge islands
Cul-de-sac’ed Crisanto Avenue

Rengstorff Ave Grade Separation

In January 2024, the City Council was presented with updates regarding the two grade separations projects - Castro Street and Rengstorff Avenue, including project status, cost estimates and benefits (see Council Report dated January 23, 2024). Due to a limited funding sources and a very significant funding shortfall for the Castro Street Project, the City Council prioritized the Rengstorff Avenue Grade Separation Project. City Council prioritized Rengstorff given that there is an interim solution for Castro Street, Rengstorff is more challenging for pedestrians and bicyclists compared to Castro, and reducing the shortfall for Rengstorff would make it more competitive for federal grant funding application.

The Project is currently in the Final Design and Right of Way Acquisition Phase and is scheduled to be completed in early 2026 and may begin construction shortly after pending funding availability.
