Yellow Bus in Traffic

St. Hilary bus

We are pleased to announce that beginning with the 2025-26 school year, the TPTA will offer a pilot express bus service exclusively for St. Hilary School students, with the aim of reducing peak-hour traffic congestion on Tiburon Boulevard. This limited service will make two stops in the morning (Spencer Avenue and Strawberry Frontage Road near In-N-Out) before arriving at school and will make one centrally located afternoon stop after school (Strawberry Frontage Road near Piatti). Because this is a limited, dedicated SHS bus, annual passes will cost $500 one way or $1,000 round trip, totaling less than $3 per ride.
