Watkins Mill Interchange
The Maryland Department of Transportation’s State Highway Administration delivered more travel options for motorists, truck drivers, cyclists, pedestrians, and transit users while providing tremendous regional economic benefits.
In June 2020, by way of MDOT SHA’s first virtual ribbon-cutting event, Lt. Governor Boyd Rutherford, MDOT Secretary Greg Slater, MDOT SHA Administrator Tim Smith, and Montgomery County and Gaithersburg officials announced the completion of the three-year, $126 million interchange project at I-270 and Watkins Mill Road.
The I-270 corridor is known as the Montgomery County’s Technology Corridor and is home to dozens of existing businesses and planned development in the Gaithersburg area. The congestion-relief project includes a new bridge over I-270, ramps connecting Watkins Mill Road with the interstate, and enhanced accessibility for bicyclists and pedestrians. The project improved access to the Gaithersburg Medical Center, Metropolitan Grove MARC Station, the Montgomery County Police Department, and local neighborhoods and businesses. Completed six months ahead of schedule, this long-awaited project is just one example of the work MDOT SHA has accomplished during Maryland’s COVID-19 State of Emergency while maintaining safe conditions for commuters and work crews.
