Much of this segment of freeway, especially near Berkeley, is built on landfill. 40, carries Interstate 80 almost due north toward Vallejo. This freeway, which was originally built as U.S. Upon leaving the Bay Bridge, Interstate 80 enters the MacArthur Maze, then turns north at Oakland to parallel the bayshore via the Eastshore Freeway. The old eastern span was subsequently demolished. A bicycle/pedestrian path also follows the eastern span all the way to Yerba Buena Island.

Unlike the tunnel and western span, the eastern span now has side-by-side travel lanes rather than double-deck travel lanes. The causeway was completed first, and the single-anchored suspension segment was completed second. The new eastern span is a single-anchored suspension span with a single tower, along with a long approach causeway coming from Oakland. The old eastern span was permanently closed on August 28, 2012, to allow for the shifting of traffic onto the new span. After a decade of work, the new eastern span opened to traffic on September 2, 2013. However, the original eastern span was not up to those specifications, and construction began in 2002 to replace it. The Yerba Buena Tunnel, which passes through Yerba Buena Island, is the largest diameter transportation bore tunnel in the country and possibly the world.Įarthquake retrofitting improved the western (traditional suspension) span between 19, which is now up to current specifications.

In 1963, the bridge converted to the current configuration with eastbound traffic on the bottom level and westbound traffic on the top level. From 1936 to 1963, the lower deck carried rail, truck, and auto traffic, while the top deck carried auto traffic only in both directions. The bridge was originally double-decked through all three segments. It was also the first suspension bridge to serve San Francisco (as it opened approximately six months prior to the Golden Gate Bridge on U.S.

The Bay Bridge originally consisted of three identifiable segments: western span (suspension bridge with four towers and mid-span anchorage), Yerba Buena Tunnel, and eastern span (a cantilever through truss bridge with an approach causeway). The bridge initially carried the dual designation of U.S. The original bridge was under construction from July 9, 1933, and it opened to traffic on November 12, 1936. The San Francisco-Oakland Bay Bridge carries Interstate 80 across San Francisco Bay. The skyway grants spectacular views of Downtown San Francisco as it connects directly to the San Francisco-Oakland Bay Bridge. 101, I-80 immediately ascends to the James Lick Skyway, which was rebuilt in its entirety in the late 2000s. Interstate 80 begins its transcontinental route in San Francisco, the city by the bay. Business Loop I-80 (Capital City Freeway) - Sacramento.40 alongside the Truckee River to Verde and Reno, Nevada. The remainder of Interstate 80 overlays historic U.S. The often snow covered stretch culminates at Truckee, where SR 89 and SR 267 tie in from scenic Lake Tahoe. Gradually gaining elevation, I-80 arcs northeast into the Sierra Nevada, passing through Blue Canyon, Emigrant Gap and Yuba Pass. I-80 continues northeast through suburban areas to Roseville and Auburn. 50 and Business Loop I-80 form an urban loop to the south. The freeway bypasses the city to the north while U.S. Making a gradual northeasterly turn, Interstate 80 passes through Vallejo to Fairfield, Vacaville, Davis and the Sacramento metropolitan area. The northerly course extends to the Alfred Zampa Bridge spanning Carquinez Strait. Combining with Interstate 580 along a wrong-way concurrency, I-80 turns north through Berkeley to Richmond.

The toll bridge consists of two spans, a suspension bridge east to Yerba Buena Island, and a self-anchored suspension bridge from the island to Oakland. Starting in San Francisco, I-80 spans San Francisco Bay across the San Francisco-Oakland Bay Bridge. Interstate 80 is a major freeway across northern California. Built over the course of 11 years and at a cost of over $6.5 billion, the signature span connects Oakland with Yerba Buena Island. The new eastern span of the San Francisco-Oakland Bay Bridge opened to traffic on September 2, 2013.
