The San Francisco Bay Area (referred to locally as the Bay Area) is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the major cities and metropolitan areas of San Jose, San Francisco, and Oakland, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.68 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels, and commuter rail. The combined statistical area of the region is the second-largest in California (after the Greater Los Angeles area), the fifth-largest in the United States, and the 43rd-largest urban area in the world with 8.80 million people.

The Bay Area has the second-most Fortune 500 companies in the United States, after the New York metropolitan area, and is known for its natural beauty, liberal politics, entrepreneurship, and diversity. The area ranks second in highest density of college graduates, after the Washington, D.C. metropolitan area and performs above the state median household income in the 2010 census; it includes the five highest California counties by per capita income and two of the top 25 wealthiest counties in the United States. Based on a 2013 population report from the California Department of Finance, the Bay Area is the only region in California where the rate of people migrating in from other areas in the United States is greater than the rate of those leaving the region, led by Alameda and Contra Costa counties.

Bayshore Freeway in San Mateo.jpg

The Bayshore Freeway is a part of U.S. Route 101 in the San Francisco Bay Area of the U.S. state of California. It runs along the west shore of the San Francisco Bay, connecting San Jose with San Francisco. Within the city of San Francisco, the freeway is also known as James Lick Freeway. The road was originally built as a surface road, the Bayshore Highway, and later upgraded to freeway standards. Before 1964, it was mostly marked as U.S. Route 101 Bypass, with US 101 using the present State Route 82 (El Camino Real).

Before the Dumbarton and San Mateo-Hayward Bridges were built across the San Francisco Bay in the 1920s, San Francisco was bottled up at the north end of a long peninsula, with driving south on El Camino Real towards San Jose as the only reasonable alternative to the ferries for crossing the bay. The first of several highways built as an alternate to El Camino Real was the Skyline Boulevard, which was added to the state highway system in 1919. A second route, the Bay Shore Highway (Route 68), became a state highway in 1923, but only from the San Francisco city limits into San Mateo County, where the Dumbarton Bridge would begin. Just prior to the start of construction on the Dumbarton Bridge, San Francisco Supervisor Richard J. Welch noted that the Bay Shore Highway would need to be built all the way to San Jose as an escape valve for the additional traffic that the bridge would attract. (more...)
