Bridge underclearance over a navigable waterway is the estimated vertical distance above the normal water surface level. Underclearance for tidal waters is defined as the measure above mean high tide. These levels vary considerably from season to season; for tidal waters they vary daily. Because of these variations, we provide the elevations in this chart as a general public service. If you are a boater, you must verify this information by taking field measurements before your journey. The Maryland Department of Transportation State Highway Administration (MDOT SHA) does not accept liability for inaccurate information.

* These are movable bridges; the underclearance shown is for bridge in a closed condition. Click here for schedule of opening and closings.
