M3-Marsh Road Shuttle

General information



The M3-Marsh Road Shuttle is a free commuter shuttle open to everyone. It runs between the Menlo Park Caltrain station and the Marsh Road-area business parks. These business parks include the areas by Bohannon Dr, Scott Dr, Constitution Dr, Chrysler Dr, Commonwealth Way, and Jefferson Dr.

The shuttle's schedule operates Monday through Friday, in the AM from about 6:45am-10:00am and in the PM from about 2:15pm-6:15pm to sync with Caltrain's peak period schedule. The shuttle bus is wheelchair-accessible and has a rack that can accommodate two bicycles.

For those with destinations in the Bohannon Dr-area business parks, Stanford Marguerite offers service from the Stanford University campus (along Quarry Rd) and Menlo Park Caltrain on its Bohannon shuttle. This service runs every 30 minutes, from 7:00am-6:30pm, offering additional options to the M3-Marsh Road Shuttle peak AM and PM period service.

The Menlo Park shuttle service has been in operation since 1989. The shuttle service is funded through generous grants from San Mateo County Transportation Authority, Bay Area Air Quality Management District and the City of Menlo Park.
