Montgomery County Executive Elrich and County Council President Glass Announce Development on the Great Seneca Transit Network, Bringing Fast, Equitable Access to Medical Centers and Educational Facilities in Rockville and Gaithersburg

For Immediate Release: Tuesday, November 28, 2023

Montgomery County Executive Marc Elrich, County Council President Evan Glass and the County Department of Transportation (MCDOT) today announced the beginning of Phase 1 of the Great Seneca Transit Network (GSTN) at a ceremonial “groundpainting” of dedicated bus lanes at the Traville Parkway Transit Center in Rockville. 


County Executive Elrich and Council President Glass were joined at the event by Council Vice President Andrew Friedson, Councilmembers Marylin Balcombe and Natali Fani-González, MCDOT Director Chris Conklin and Executive Director of the Universities at Shady Grove in Rockville Anne Khademian. 


Phase1 of the Great Seneca Transit Network will include two new Ride On extRa bus service lines. The project will continue through spring, with service to begin late summer 2024.  


The two new bus lines, designated as “Lime” and “Pink,” will run east-west connections between the Shady Grove Metro to the Universities of Shady Grove in Rockville. The Pink line will link the busy Shady Grove corridor with the Life Sciences Center via Medical Center Drive.  The Lime line will use I-370 to provide an express route to RIO, Crown Farm and the heart of the Life Science Center at Adventist HealthCare Shady Grove Medical Center.    


“The opening of the Great Seneca Transit Network will be a big boost to the residents and those who work in the Rockville, Gaithersburg, and Shady Grove communities,” said County Executive Marc Elrich. “The addition of these two express bus routes and dedicated bus lanes will connect Metrorail directly to the Life Science Center and Universities at Shady Grove. The workforce within this transit corridor has nearly doubled since 2010 and these new routes will help support the public transportation needs of employees and students. I have supported this project for years and expect it to help grow our biotech sector and spur economic development.”
