The Maryland Department of Transportation State Highway Administration (MDOT SHA) does not guarantee that the vertical clearance limitations shown on this page are accurate at all times and places. Due to resurfacing of highways, repairs and construction, these listed heights are subject to change. Heights may also vary from position to position under a structure. If you need exact dimensions to determine a route, you must take field measurements before your journey.

Baltimore County - Underclearance over Navigable Waterways

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. MDOT SHA does not accept liability for inaccurate information.
