The study corridor includes the area from the I-270/I-370 interchange in Montgomery County to the US 15 intersection at Biggs Ford Road in Frederick County.

The I-270/US 15 corridor is a vital link to other highways in the Maryland and Washington, DC region. I-270 begins at the Capital Beltway (I-495) and extends north to I-70 in Frederick, Maryland. The corridor acts as an artery between the nation’s capital and points north and west. In Maryland, US 15 extends from the Virginia state line to the Pennsylvania state line and provides a critical north-south route through the region.

The study corridor is heavily used by commercial vehicles, as well as commuters. The level of performance for the roadway is currently sub-par, with motorists wasting precious time and gasoline sitting in traffic on a daily basis. Population projections for Frederick County and Montgomery County indicate the problem will only get worse. It is projected that by 2025, Frederick County’s population will have increased by 97,639 from the year 2000, and Montgomery county’s population will have increased by 165,935. That translates into thousands more cars on our roadways and hundreds more hours of congestion delays for Marylanders.
