On July 2, the Dumbarton Express lines DB and DB1 began new and expanded service between the East Bay and the Peninsula via the Dumbarton Bridge. A proposal to expand the service was approved by the AC Transit Board of Directors in April, following a period of public comment and a public hearing.
- Increasing overall service levels by approximately 80 percent; in particular, Line DB1 will offer more than three times the current number of daily trips, and additional Line DB trips will be added earlier in the day and later in the evening.
- Extension of Line DB from the Palo Alto Caltrain station to the Stanford Oval to help relieve overcrowding on AC TransitâsÂ Line U.
- Discontinuation of the segment of Line DB south of the Caltrain station, along El Camino Real and Page Mill Rd.
- Extension of Line DB1, as well as increased frequency, to serve the entire Page Mill/Deer Creek Rd. loop, including the eliminated Line DB route segment along Page Mill Road*.
In addition, all DB Express buses are nowÂ equipped with new wi-fi technology, and Real-time departures informationÂ will be available soon.Â
