(April 3, 2018) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will hold four public open houses in April for the I-495 and I-270 Managed Lanes Study, which is the first step for public input on the Traffic Relief Plan to reduce congestion on two of the state’s most heavily traveled highways. The National Capital region is one of the most congested in the nation with some of the highest commuting times.

“Understanding the local perspective will help us determine the best plan to reduce traffic congestion, increase economic development, enhance safety and return quality of life to Maryland commuters in this area,” said Transportation Secretary Pete K. Rahn.

MDOT SHA, in conjunction with the Federal Highway Administration (FHWA), will prepare an Environmental Impact Statement for the I-495 and I-270 Managed Lanes Study to identify innovative transportation solutions to reduce congestion.

The study considers improvements along the entire length of I-495 (Capital Beltway) in Maryland, as well as the entire length of I-270 (Dwight D. Eisenhower Memorial Highway) up to I-70 in Frederick County, Maryland. The I-495 and I-270 Managed Lanes Study extends along I-495 from south of the American Legion Bridge in Virginia to east of the Woodrow Wilson Bridge and on I-270 from I-495 to I-370, including the east and west spurs. The study will include a review of existing and future traffic, existing roadway infrastructure, and environmental conditions to identify alternatives and assess potential impacts.

The four public open houses will solicit public input regarding the scope of the study, including the purpose and need, potential alternatives to be considered, and environmental impacts to be evaluated.
