Maryland Route 97
MD 97 begins at an intersection with US 29 and MD 384 (Colesville Road) in downtown Silver Spring in Montgomery County, heading north on Georgia Avenue, a six-lane divided highway. From the route’s southern terminus, Georgia Avenue continues south as part of US 29 toward Washington, D.C. MD 97 passes commercial areas of high-rise buildings in Silver Spring before heading into residential neighborhoods. The route intersects the northern terminus of MD 390 (16th Street), which heads south and becomes 16th Street Northwest upon entering the District of Columbia. Washington Metro's Red Line begins to run below the route at this point. It continues north as a six-lane undivided road with reversible lanes through commercial areas before coming to a modified cloverleaf interchange with I-495 (Capital Beltway).
