Lower Mississippi River Bridges Air-Draft Calculations:

​The above clearances were calculated this morning using gauge readings provided by the Army Corps of Engineers. As a guide the pilots require at least an additional 3 feet of clearance for the Vessel's Air Draft.  The individual pilot assigned to the vessel will make the final determination of the vessel's allowable clearance.  Actual clearance should be verified when ordering pilot services.
