The Maryland Department of Transportation State Highway Administration (MDOT SHA) is undertaking the I-495 and I-270 Managed Lanes Study to address traffic congestion along the entire length of I-495 (Capital Beltway), as well as the entire length of I-270 (Dwight D. Eisenhower Memorial Highway) up to I-70 in Frederick County, Maryland, among the busiest routes in the region. The Maryland-National Capital Park and Planning Commission (M-NCPPC) has been selected by MDOT SHA as a cooperating agency in the project.
At various stages of the project, the M-NCPPC, through its Montgomery County Planning Department, Montgomery County Department of Parks, Prince George’s County Planning Department and Prince George’s County Department of Parks and Recreation, will review study process, analysis, and any potential environmental and community impacts of alternatives proposed to address congestion within the specific study area. The M-NCPPC will review the proposed alternatives for alignment with the National Environmental Policy Act (NEPA) requirements and best practices. Its findings will be issued to the public as soon as they are available.
