Who We Are

We’re the San Mateo County Transportation Authority (SMCTA), better known as “The TA.”

You feel the impact of our work every day — in the highway interchange that no longer backs up, the potholes that get repaired, the free shuttle that connects Caltrain riders to workplaces, the raised railroad crossing that improves safety and keeps people moving, and the bike and pedestrian paths that make it easier to get around your neighborhood.

The TA invests your local tax dollars to fund transportation improvements according to the spending plans that you — the voters of San Mateo County — approved at the ballot box.
