Program Overview

The I-495 & I-270 P3 Program is a historic effort to reduce congestion for millions of travelers in the National Capital Region by seeking input from the private sector to design, build, finance, operate, and maintain improvements on both I-495 and I-270. Improvements will be focused to transform these overloaded interstates to allow people to reach their destinations faster and to remove overflow traffic from the local roads.

The overall I-495 & I-270 Public-Private Partnership (P3) Program will include improvements for over 70 miles of interstate in Maryland including:

  • I-495 (Capital Beltway) from south of the George Washington Memorial Parkway, including improvements to the American Legion Bridge over the Potomac River, to west of MD 5 and
  • I-270 (Dwight D. Eisenhower Memorial Highway) from I-495 to I-70, including the east and west I-270 spurs.

Program Elements

I-495 & I-270 Managed Lanes Study

The I-495 & I-270 Managed Lanes Study is the first element in the P3 Program undergoing the environmental review process. The I-495 & I-270 Managed Lanes Study Environmental Impact Statement (EIS) will include a review of existing and future traffic, roadway, and environmental conditions to identify alternatives and assess potential impacts. The limits for this study extend along I-495 from south of the George Washington Memorial Parkway, including improvements to the American Legion Bridge, to west of MD 5 and along I-270 from I-495 to north of I-370, including the east and west I-270 spurs.

I-270 from I-370 to I-70 Pre-NEPA

The I-270 from I-370 to I-70 pre-NEPA activities extend along I-270 from I-370 in Montgomery County to I-70 in Frederick County, Maryland. During these initial activities, MDOT SHA will conduct environmental planning activities prior to starting a study under the National Environmental Policy Act (NEPA). This will include identifying the project’s purpose and need, developing a range of alternatives, reviewing existing and future traffic volumes and existing environmental conditions, and engaging the public.

Opportunity MDOT

As the Maryland Department of Transportation (MDOT) strives to provide travelers with congestion relief through the I-495 & I-270 Public-Private Partnership (P3) Program, the agency has created Opportunity MDOT, a source for small, minority-, women- and veteran-owned businesses and disadvantaged businesses to access valuable resources.

The goal of Opportunity MDOT is to help strengthen and grow Maryland’s businesses, workforce and economy for generations – one opportunity at a time. In addition, more diverse, inclusive teams foster innovative ideas, broaden stakeholder involvement and successfully deliver transportation projects in new and better ways.

Opportunity MDOT is engaging and empowering small businesses and job seekers to access training, advisory services and advanced industry resources like never before.

Partnering with the Private Sector

Concurrent with the I-495 & I-270 Managed Lanes Study, MDOT SHA will be seeking proposals from the private sector to enter into a Public-Private Partnership (P3), to develop innovative approaches to design, build, finance, operate, and maintain the potential improvements developed through the environmental studies being conducted.
