The City of Mountain View and the Peninsula Corridor Joint Powers Board (JPB) have been collaborating on the Preliminary Engineering and Environmental Clearance Phase of the Rengstorff Avenue Grade Separation Project. A community meeting was held on November 2, 2020, in which staff presented proposed project features, layout, temporary construction impact, and received community input.

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 Preliminary Engineering and Environmental Clearance Phase is scheduled to be completed early 2021 and staff plans to continue on to the final design phase in 2021 pending funding availability.
