Highway 680 uses the Benicia-Martinez Bridge to cross the Carquinez Straight. It actually consists of two separate bridges, one for northbound traffic and one for southbound traffic. A railroad bridge is wedged between the highway bridges. There is a $4 toll that is charged only in the northbound direction. Costing the same as the seven mile long Bay Bridge, this toll seems overpriced. Actually a regional transportation authority has set all the bridge tolls in the Bay Area (except the Golden Gate Bridge) equally high. The toll plaza at the bridge gets congested at commute hours.
Since we are on the water, we have a marina. The picture shows the guest dock. The Marina is off East Second Street, so you can walk to downtown. It takes a sail boat about 90 minutes to make the trip from San Francisco.
