Event Center Traffic

The San Mateo County Event Center is phasing out as an appointment-only COVID-19 vaccination site. We are proud to support our County partners on this critical public health effort and we are working closely to manage potential impacts.

Please note the following traffic pattern changes to the area. 

Traffic Pattern Changes

25th Grade Separation Project

The 25th Grade Separation Project prompted the following traffic pattern changes: 

E. 25th Avenue at S. Delaware Street

  • April 1 – Aug. 15, 2021 – closed in both directions

Clean Water Program

Saratoga Drive

  • Eastbound lanes are closed to facilitate the construction of the City’s Clean Water Program Underground Flow Equalization System
  • Westbound lanes now facilitate both eastbound and westbound traffic. Eastbound Saratoga from Delaware Street is now open to through traffic. 
  • Westbound Saratoga from 28th Avenue has only one lane open to through traffic. 

At Event Center Entrance on Saratoga Drive

  • Traffic light replaced with stop signs.

Traffic patterns will continue to be updated as needed. We are working with SamTrans to restore bus service to Saratoga Drive. We thank our neighbors in the area for their understanding and cooperation. Access to residences will be maintained, but detours may be needed to get to your home.
