Light rail train.The I-270/US 15 Multi-Modal Corridor Study is a one-of-a-kind project in Maryland with a simple goal…to make life easier for Maryland residents. This potential project is moving forward with new momentum and is widely supported by commuters in Frederick County and Montgomery County. A joint effort by the Maryland State Highway Administration and the Maryland Transit Administration, the Corridor Study examines Frederick County's and Montgomery County's most congested areas, a 30-mile stretch running from the intersection of US 15 and Biggs Ford Road along I-270 to the Shady Grove Metro Station. This Corridor Study explores options to ease congestion by making highway improvements in conjunction with proposed transit options, such as bus rapid transit or light rail transit, along a dedicated corridor known as the Corridor Cities Transitway.
