Peninsula Interchange Project

Project Update
A project update will be held on Monday, November 7, 2016 at the regular City Council meeting.  Check the City Council agenda for more information.

Peninsula AveProject Description
This project will ultimately relocate the US 101 southbound on- and off-ramps from East Poplar Avenue to Peninsula Avenue to eliminate the partial interchange condition and create a single, full access interchange at Peninsula Avenue and Airport Boulevard. This will result in an improvement to the safety and traffic operations of the southbound US 101 ramps and the intersection of East Poplar Avenue and North Amphlett Boulevard.

The project will provide improvements to the bicycle and pedestrian movements through the intersection of Peninsula Avenue and North Bayshore Boulevard. The project will also provide improvements to local streets to facilitate circulation and property access.  This is considered the long term solution for the safety issues at the Poplar on/off ramps.

The US-101/Peninsula Avenue Interchange Project received grant funding from the San Mateo Transportation Authority (TA) to complete the initial Caltrans documents, including the Project Study Report (PSR).  San Mateo is the sponsoring agency.  This project will complete a PSR-PDS (Project Development Support) with Caltrans in order to request programming for the PA&ED (Project Approval & Environmental Document) phase and capital support to relocate the US-101 southbound on/off ramps from East Poplar Avenue to Peninsula Avenue.
