Look across the bay. Can you see the tiny remnants of a wooden trestle bridge that once connected the place where you are standing to the sandspit?

The Navy built the bridge in 1942 as part of its efforts to create a functional Navy base in Morro Bay harbor. The harbor was rebuilt as a Navy Section Base to support small deepwater "mosquito" patrol boats, with a safer entrance, better docks, and a more usable staging area.
