Highway 17 Express

The Highway 17 Express is an Amtrak Thruway Motorcoach route provided by a consortium of entities that provides regional service between San Jose and Santa Cruz County in the South Bay of the San Francisco Bay Area. The service is so called because it travels on California State Route 17. It is operated by the Santa Cruz Metropolitan Transit District.

The bus service is a consolidation of corridor-based commuter service between Santa Cruz and job centers in the Silicon Valley, with more limited service beyond Santa Cruz to Soquel. It passes through the State Route 17 communities of the Santa Cruz Mountains including Scotts Valley, Redwood Estates, Summit, and Pasatiempo and is combined with feeder and delivery service for several Amtrak California lines serving Diridon Station in San Jose, a regional intermodal hub where passengers may transfer to VTA buses or light rail in addition to ACE, Capitol Corridor, Caltrain, and also many regional Amtrak routes. During the week the service extends beyond Diridon Station with direct service to downtown San Jose; on weekends it terminates at the station.
