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.
This chart shows structures within the MDOT SHA system that cannot support legal weight vehicles. For help moving an overweight load, call 1-888-375-1084.
