San Francisco Bay Trail

The San Francisco Bay Trail is a bicycle and pedestrian trail that will eventually allow continuous travel around the shoreline of San Francisco Bay. As of 2019, 356 miles (573 km) of trail have been completed. When finished, the Bay Trail will extend over 500 miles (805 km) to link the shoreline of nine counties, passing through 47 cities and crossing seven toll bridges. It is a project of the Association of Bay Area Governments (ABAG) and the Metropolitan Transportation Commission (MTC).

Bay Area Ridge Trail

The Bay Area Ridge Trail is a planned 550-mile (890 km) multi-use trail along the hill and mountain ridgelines ringing the San Francisco Bay Area, in Northern California. When complete, the trail will connect over 75 parks and open spaces. The trail is being designed to provide access for hikers, runners, mountain bicyclists, and equestrians. It will be accessible through trailheads near major population centers, while the trail will extend into more remote areas. The first trail section was dedicated on May 13, 1989.

The state built the 1.7 miles (2.7 km)-long Carquinez Scenic Drive along the southern shore of the strait in 1912. Decades later, it turned the road over to Contra Costa County. Major storms and landslides in 1983 caused huge gaps in the road, forcing its permanent closure to auto traffic. Instead, the county decided to convert the abandoned road into a trail for exclusive use by hikers, joggers, cyclists and equestrians. EBRPD negotiated with Contra Costa County for nearly a decade before it reached agreement in December 2012 on an easement that allowed converting the idle roadway to a trail. Even so, it still cost about $5.5 million to install piers, drains and walls to ensure stability of the new trail. It took several years to obtain sufficient funds for this project, [lower-alpha 1] The new trail, which did not open for public use until the Fall of 2014, was named for former U.S. Representative George Miller (D-Martinez), who was instrumental in obtaining $3.5 million in Federal funds for the project.
