The I-495 and I-270 Managed Lanes Study considers improvements along I-495 (Capital Beltway), as well as along I-270 (Dwight D. Eisenhower Memorial Highway). The Managed Lanes Study will evaluate a range of alternatives within the specific area of I-495 from the Virginia side of the American Legion Bridge in Fairfax County to the Maryland side of the Woodrow Wilson Bridge and on I-270 from I-495 to I-370. A notice of intent to complete an environmental impact statement (EIS) for the Managed Lanes Study area was issued by the Federal Highway Administration on March 16, 2018.

The purpose of the I-495 and I-270 Managed Lanes Study is to develop a travel demand management solution that addresses congestion, improves trip reliability on I-495 and I-270 within the study limits and enhances existing and planned multimodal mobility and connectivity. MDOT SHA intends to utilize a public-private partnership (P3) in order to design, construct, finance, operate and maintain any proposed infrastructure improvements.

Prince George’s County Planning Department and Prince George’s County Department of Parks and Recreation are reviewing MDOT SHA’s Purpose and Need Statement for the I-495 and I-270 Managed Lanes Project. As stewards of the natural and built environment, and as a cooperating agency on this project, as identified as such by SHA, Prince George’s Planning and Parks Department’s are working to assess the goals, objectives, and criteria from a land use perspective.

Managed lanes are an option to provide travelers with a choice of single-occupant vehicle (SOV) travel in specific areas of roadways. Any selected build alternative is likely to have significant effects on parkland and the associated facilities, programs and natural and cultural resources in both counties as well as significant community impacts. In order to address the impact of the alternatives, the Managed Lanes Study will ultimately evaluate the impact to properties and resources based upon the Alternatives Retained for Detailed Study (ARDS) as a result of the public input based on criteria outlined in the Purpose and Need Study.  The magnitude of the impacts will be evaluated by M-NCPPC staff, and required mitigation proposed by MDOT SHA will ultimately be presented to the M-NCPPC as the project progresses.
