Crossing the San Francisco-Oakland Bay Bridge
The San Francisco-Oakland Bay Bridge, on Interstate 80, crosses the San Francisco Bay and connects San Francisco and Alameda counties It is made up of two bridge segments: a skyway structure/single anchored suspension bridge between Oakland and Yerba Buena Island for vehicles with a protected bicycle and pedestrian pathway, and a suspension span from the island to San Francisco for vehicular traffic.
The Bay Bridge Trail is a part of the San Francisco Bay Trail. The Bay Bridge Trail is named in honor of Alex Zuckermann, the late East Bay Bicycle Coalition founder and Bay Bridge Trail advocate.  A plaque bearing his name is located on the trail which extends over 4 miles from Emeryville to Yerba Buena Island (San Francisco).  The first two-thirds of the Bay Bridge Trail, from Emeryville to the Oakland touchdown, opened in September 2013. In October 2016, the Bicycle and Pedestrian Path across the East Span of the San Francisco-Oakland Bay Bridge opened, enabling cyclists and pedestrians to traverse past the East Span’s signature 525-foot tower to the new landing area and Vista Point on Yerba Buena Island. The length of the path on the East Span of the Bay Bridge is 2.2 miles from Oakland to Yerba Buena Island.
