The East West Highway–Old Georgetown Road Line, designated Route M70, is a daily bus route operated by the Washington Metropolitan Area Transit Authority between Silver Spring station of the Red Line of the Washington Metro and Westfield Montgomery Transit Center. This route replaced the former Bethesda–Silver Spring Line consisting of routes J1 and J2. The M70 follows roughly the same routing as the previous J2 route, except that westbound buses do not serve the bus loop at Medical Center Station and instead stop across the street along Rockville Pike.
