The Washington, D.C. area has some of the worst traffic congestion in the United States, and with up to 200,000 vehicles on the roadway each day, drivers on I-66 in Northern Virginia experience 8 to 10 hours of daily congestion.

In 2016, the Commonwealth of Virginia selected I-66 Express Mobility Partners to finance, design, build, maintain and operate express lanes on Interstate 66 Outside the Beltway. The project will transform this critical Northern Virginia artery to relieve congestion, improve safety and provide more predictable travel times.  The new express lanes will open in December 2022, and when complete, the expanded highway is expected to move 2,000 to 4,000 more people per hour along the corridor.

I-66 will be expanded – from the Capital Beltway (I-495) to Gainesville (US Route 29) – to include three toll free general purpose lanes and two Express Lanes in each direction with a state-of-the-art open-road electronic toll collection system. Expanded transit service, park-and-ride lots, interchange enhancements and 11 miles of shared use path connecting existing and planned trails will further improve travel along I-66 while creating more multimodal travel options. HOV 3+ will be able to access the Express Lanes at no cost. The project also includes modernized design enhancements which will improve safety throughout the corridor.

The Transform 66 Outside the Beltway P3 project is the first major procurement to follow Virginia’s reformed Public-Private Partnership (P3) process that was designed to increase accountability, transparency and competition in P3 projects. As an innovative and efficient public-private partnership, this project will be completed at a $2.5 billion net savings for the Commonwealth of Virginia.


In 2016, the Commonwealth of Virginia selected I-66 Express Mobility Partners for the financing, design, construction, maintenance and operation of the Interstate 66 dynamic toll located in the immediate vicinity of Washington, DC. The project will transform this critical artery in Northern Virginia to relieve congestion, improve safety and provide more predictable travel times.

This project is the first award after modification of the state’s bidding process for P3 projects. It was modified with the intention of improving transparency and competitiveness in P3 projects. This innovative and efficient public-private partnership has meant significant savings for the Commonwealth of Virginia.


Cintra is a member of the I-66 Express Mobility Partners consortium, along with Meridiam and APG. Together, we are investing more than $3.5 billion in Virginia’s infrastructure over the life of this project. This includes the $2.3 billion project construction, a $579 million upfront concession fee to the Commonwealth to fund additional improvement projects in the corridor, $800 million to expand transit service in the corridor and $350 million for other projects to improve the I-66 corridor over the next 50 years.

The design-build contractor for the project is FAM Construction, a joint venture between Ferrovial Construction and Allan Myers, VA.
