Welcome to the CCT

We welcome you to the Corridor Cities Transitway (CCT) website and encourage you to browse through the website to stay connected to the project. We have provided maps, graphics, and text which is designed to inform you about the project and offer ways to contact us with any questions or comments you may have.

The CCT is a 15 mile project in Montgomery County, Maryland from the COMSAT facility near Clarksburg, Maryland to the Shady Grove Metro Station. The project has two phases. Phase I is 9 miles from Metropolitan Grove to Shady Grove. This Phase is actively underway and is currently proceeding with engineering and environmental analysis and is funded for formal environmental documentation, final design, and right-of-way acquisition. Phase II would be a future extension from Metropolitan Grove to the COMSAT facility near Clarksburg, and would be developed as land use matures and additional transportation funding becomes available.

15% Design Plans

On August 15, 2014, the CCT project team delivered 15% Concept Preliminary Engineering Plans to MTA for review. Since then, the MTA has been gathering comments on the plans from agency stakeholders such as State Highway Administration, Montgomery County Department of Transportation, the Cities of Gaithersburg and Rockville, and the Maryland-National Capital Park and Planning Commission. The plans contain more detailed engineering for the Phase I section of the CCT. This level of design detail is used to assess the environmental, cultural, and property impacts of the proposed transitway and develop a more accurate construction cost estimate.

Through the design process the transitway alignment has changed in three locations since the Locally Preferred Alternative was announced in May 2012.

  • Along the CSX tracks by Metropolitan Grove, the transitway would shift from the north side of the tracks to the south side of the tracks.
  • Along Muddy Branch Road between Darnestown Road and Great Seneca Highway, the transitway would be located in the existing median of Muddy Branch Road.
  • Near Key West Avenue, the transitway alignment would shift from the east side to the west side of Broschart Road at an intersection with an existing driveway. It would then cross under Key West Avenue.
