UFES Traffic Update – June 30, 2022

Saratoga Drive to Remain Open through Summer 2022

The City of San Mateo has good news for you! Saratoga Drive, in the vicinity of the San Mateo County Event Center and other UFES project activities, is expected to remain open through late Summer 2022. Future construction activities will require lane closures.

We will keep you updated with details as we get closer to the planned reclosure, so please keep an eye on your inbox and text messages. Please watch for signs indicating traffic pattern changes.

We thank you for your continued patience and cooperation as we make steady progress toward the completion of our sewer system improvements.
