Known as Ordnance Road, the state highway runs 2.16 miles (3.48 km) from MD 2 in Glen Burnie east to MD 173 in Brooklyn Park at the city limits of Baltimore.

MD 710 provides access to the Defense Logistics Agency Curtis Bay Depot, a unit of the General Services Administration.

The state highway is named for the federal site's prior use as a U.S. Army Depot.

Beyond MD 10, the state highway curves to the northeast, crosses a branch of Furnace Creek, and reduces to a two-lane undivided road.

The state highway curves east and has a grade crossing of CSX's Curtis Bay Branch underneath Interstate 695 (I-695, Baltimore Beltway).
