The Beach Drive bascule Bridge straddles the opening of Massalina Bayou near GIWW Mile 290 and about four statute miles northeast of the Saint Andrews Bay Inlet.
Use NOAA Chart 11390.
Massalina Bayou is protected by a wood jetty and pier located on the west side of the bayou entrance. Keep a close watch for arriving and departing vessels making their maneuvers here.
Depths at mid-channel in the entrance are reported to be eight feet or more, but with most gulf locations, a tight watch on the depth sounder and slower speeds are recommended. The bridge has a closed vertical clearance of seven feet with 40 feet of vertical clearance in the center span.
