Mare Island Strait, at the mouth of the Napa River, is between the mainland and Mare Island. The project depth for the Mare Island Strait Channel, from the entrance to just S of the Vallejo-Mare Island Causeway Bridge, about 2.9 miles above the entrance, is 30 feet.
The entrance to Mare Island Strait is between two dikes. On the E side of the entrance, Dike No. 9 extends about 700 yards SW from the mainland and on the W side, Dike No. 14 extends about 500 yards SE from Mare Island; both dikes have submerged outer sections. Dike No. 9 is marked at the outer end by a light and Dike No. 14 is marked at the outer end by a lighted buoy.
Vallejo, on the E shore of Mare Island Strait, is the terminal of a railroad connecting interior N points. A large flour mill is prominent S of the railroad yard. A passenger ferry operates between Vallejo and San Francisco.
The Vallejo-Mare Island causeway and lift bridge connects Mare Island with the city of Vallejo. It has a lift span with a clearance of 100 feet up and 12 feet down. The bridge is equipped with radiotelephone. The bridgetender monitors VHF-FM channel 16 and works on channel 13; voice call, Mare Island Causeway Bridge. Just above Sears Point, 1 mile above Vallejo, a fixed highway bridge with a clearance of 100 feet crosses the strait. A public fishing pier is close S of this bridge and extends about 350 yards from the E side of the strait. A Navy reserve fleet pier is on the W side of the strait between Vallejo-Mare Island causeway lift bridge and the fixed bridge just above Sears Point. If practical, approach the bridges only when running against the current.
