Locally Preferred Alternative for the CCT was identified in May, 2012 by the State of Maryland. The CCT project was defined by a Phase I, 9 mile project and a Phase II, 6 mile future extension. The six mile extension is from Metropolitan Grove to the COMSAT facility near Clarksburg in Montgomery County, Maryland. This six mile extension is not currently funded for planning, design, or construction and would be designed and constructed in the future as land use matures and transportation funding becomes available. The extension would require additional environmental documentation under the National Environmental Protection Act (NEPA) to be eligible for federal funds.

The Corridor Cities Transitway (CCT) will be a high-quality Bus Rapid Transit (BRT) line operating along a 9-mile corridor from Shady Grove Metrorail station tothe Metropolitan Grove MARC station in Montgomery County, Maryland.Click here to view a map of the Phase I, 9 mile project.
The CCT will be located entirely within Montgomery County, Maryland, and will provide efficient travel, serving both local and long distance commuters. The project will provide transit service to new and existing centers of commerce, residential, and educational development, including King Farm, Crown Farm, Life Sciences Center, The Universities at Shady Grove, Kentlands, and Metropolitan Grove. These developments have been planned and constructed as transit-oriented mixed use developments. The CCT will provide direct connections with transit services into the District of Columbia and other regional destinations by way of the MARC Brunswick Line at Metropolitan Grove and the Metrorail Red Line at Shady Grove.
The transitway would primarily be surface running with grade-separated crossings of selected roadways at busy intersections as well as over the CSX railroad near Metropolitan Grove. Bus service on the CCT will be provided with two distinct bus routes. The CCT Direct Service route will operate between the Shady Grove and Metropolitan Grove stations of the CCT, stopping at every station along the transitway. It will operate on an exclusive, dedicated transitway. The CCT Service via Universities at Shady Grove will operate along the transitway, stopping at all stations, but will divert off the transitway to serve two additional stations. For example, buses traveling from the Shady Grove station on this route would leave the transitway after the LSC Central station, stop at the Universities at Shady Grove and Traville Gateway Drive stations, return to the transitway, stop at the LSC West station and all stations to the Metropolitan Grove station.The estimated cost to construct the CCT is $545 Million (in 2012 dollars).
The proposed route of the CCT transitway is as follows:
- Beginning at the Shady Grove Metro Station with a terminal point adjacent to the Metro entrance
- Median of Metro Access Road continuing across MD 355 onto the median of King Farm Boulevard
- Aerial over Shady Grove Road and I-270
- Median of Fields Road
- Median of Decoverly Drive
- West side of Diamondback Drive to the east side of Broschart Road
- Median of Medical Center Drive
- New alignment through PSTA property
- Median of Johns Hopkins Drive
- Median of Belward Campus Drive (Future extension to Muddy Branch Road)
- East side of Muddy Branch Road
- West side of Great Seneca Highway
- Aerial crossing of Great Seneca Highway to the east side of Quince Orchard Road
- East side of Quince Orchard Road
- Aerial structure at the intersection of Clopper Road and Quince Orchard Road to the west side of Quince Orchard Road
- Aerial on west side of Quince Orchard Road from Clopper Road intersection to the north side of CSX Railroad right-of-way
- At-grade and parallel to CSX right-of-way along the north side to Metropolitan Grove Station
The proposed route for the CCT Service via Universities at Shady Grove is as follows:
- Existing Great Seneca Highway
- Existing Darnestown Road
- Existing Traville Gateway Drive
- Existing Shady Grove Road
- Existing Traville Gateway Drive
- Existing Great Seneca Highway to CCT transitway at LSC West
The fourteen stations for the CCT will be specially designed with CCT branding for easy recognition by transit users. Stations will include shelters, seating, fare machines, and both fixed and variable signage to provide customers with information on the CCT route and services as well as current operations. Safe access for pedestrians and parking for bikes will be provided at all CCT stations. The twelve along the CCT transitway with be the following locations:
- Shady Grove
- East Gaither
- West Gaither
- Crown Farm
- LSC Central
- LSC West
- LSC Belward
- Metropolitan Grove
On the CCT Service Route to Universities at Shady Grove, two stations will be located at:
- Universities at Shady Grove
- Traville Gateway Drive
The CCT would include parking at five stations: Shady Grove, Crown Farm, LSC West, Kentlands, and Metropolitan Grove.
The CCT will feature Bus Rapid Transit (BRT), a premium bus service operating on an exclusive transitway (separate from vehicular traffic), featuring 30 – 35 articulated, high capacity, rubber-tire modern vehicles equipped with multiple entry ways, off board fare payment and collection, and other amenities. To maintain the CCT vehicles, an operations and maintenance facility will be located near the Metropolitan Grove MARC Station. Service will be scheduled at regular intervals for predictability and utilize grade separation, transit signal priority and queue jumping at intersections where appropriate for reliability, much like other premium transit services. Frequency of service will be every 6 minutes during peak periods and every 10 minutes during off-peak times for the CCT Direct Service. One way travel time on the CCT from Shady Grove to Metropolitan Grove would be 38 minutes. For the CCT Service via Universities at Shady Grove buses will operate every 15 minutes. BRT systems are “branded” to distinguish themselves as a premium transit system similar in scope and quality to light rail.
Bus Rapid Transit was selected for the CCT given its comparable performance and operations and maintenance costs combined with substantially reduced capital costs compared with light rail. The BRT on the CCT will provide the quality of transit performance needed to support the substantial growth in travel demand projected for the I-270 corridor. The projected ridership on the CCT is 35,900 trips per day in 2035. Given the close coordination of land use with transportation planning and development, the selection of BRT is expected to fully support the development planned along the corridor. BRT offers service flexibility for local bus service operations that can result in improved transit quality of service throughout the transit network. BRT on the CCT also complements Montgomery County plans to develop a countywide network of BRT services as a sustainable strategy for meeting the county’s travel needs into the future.
A hiker biker trail is to be planned and designed in conjunction with development of the project. This trail would not be constructed by the MTA as part of the project, but would be developed by Montgomery County and/or others as needs warrant and funding is available.
The selection of the CCT alignment and mode was largely based on its superior performance as well as MTA’s current understanding of issues raised during the public involvement process, including the public hearings held in conjunction with the completion of the I-270/US 15 Multimodal Corridor Study Draft Environmental Impacts Study (May 2002), the I-270/US 15 Multimodal Corridor Study Alternatives Analysis/ Environmental Assessment (May 2009), and the Corridor Cities Transitway Supplemental Environmental Assessment (November 2010).
Phase II would add four stations:
- Dorsey Mill
The alignment would be extended on dedicated transitway, generally following an alignment as described below:
- Parallel the west side of I-270 from Metropolitan Grove Station to Middlebrook Rd
- Aerial crossing of Middlebrook Rd and along the western edge of the Department of Energy (DOE)
- Tunnel under Germantown Rd
- Median of Century Blvd
- Median of Dorsey Mill Rd (future extension over I-270)
- Median of Observation Dr (future extension to Clarksburg, MD) to COMSAT Station
