As of December 2020, the traffic study for this project has been completed. It is expected that a CEQA scoping meeting will be held in April 2021 and that a Draft Environmental Document would be available for public review and comment in late 2021.

Project Description:

We are proposing to relocate the existing U.S. Hwy 101 southbound on- and off-ramps from East Poplar Avenue to Peninsula Avenue in order to create a single, full-access interchange at Peninsula Avenue and Airport Boulevard. This would improve safety and traffic operations as well as reduce most typical travel times within the Peninsula Avenue interchange area for residents of both San Mateo and Burlingame.

The project would also provide bicycle and pedestrian improvements on Peninsula Avenue from just west of North Humboldt Street to North Bayshore Boulevard. 

The project is currently in the planning stages.
