Maryland Route 119 (MD 119) is a state highway in the U.S. state of Maryland. Also known as Great Seneca Highway, the highway runs 7.47 miles (12.02 km) from MD 28 in Rockville north to Middlebrook Road in Germantown. MD 119 is a four- to six-lane divided highway that connects several residential and commercial neighborhoods in Rockville, Gaithersburg, and Germantown. Great Seneca Highway was planned by Montgomery County in the late 1960s as a local relief route for traffic on parallel Interstate 270 (I-270) between the three communities. By the early 1980s, the highway had become controversial because it was proposed to pass through Seneca Creek State Park. A coalition of civic and environmental groups unsuccessfully pursued litigation to stop the highway. The National Park Service refuse
