In Northern California, US 101 is the primary coastal route providing motorists access in and out of the San Francisco Bay Area, as well as the primary commuter route between San Francisco and the North Bay. It is one of two major freeway routes connecting San Jose and Silicon Valley with San Francisco and the North Bay. It serves as a more urban alternative to the rural I-280, as US 101 runs through Peninsula cities closer to the Bay, while I-280 runs closer to the Santa Cruz Mountains and Skyline Boulevard. Through northern San Francisco, US 101 remains routed on congested city streets due to freeway revolts, leaving the city on the iconic Golden Gate Bridge. It then departs the immediate coast and continues through wine country and Redwood forests until it re-emerges coast-side at Eureka. The route provides access through the extraordinarily rugged and scenic terrain of the North Coast and into vast groves of protected Redwoods in area parks, including Redwood National and State Parks before reaching the Oregon border.
