Interstate 370 (I-370) is a 2.54-mile (4.09 km) Interstate Highway spur route off I-270 in Gaithersburg, Maryland, to the western end of the Maryland Route 200 (MD 200, Intercounty Connector) toll road at an interchange that provides access to the park and ride lot at the Shady Grove station on the Red Line of the Washington Metro. Despite the number, I-370 does not connect to I-70 itself. The road continues to the west of I-270 as Sam Eig Highway, a surface road. Along the way, I-370 has interchanges with MD 355 and Shady Grove Road. The freeway was completed in the late 1980s to connect I-270 to the Shady Grove station. I-370 was always part of the planned Intercounty Connector but was the only segment to be built at the time. The opening of MD 200 east of I-370 resulted in the truncation of I-370 to the interchange with MD 200 and the redesignation of the road leading into the Shady Grove station as MD 200A.
