U.S. Department of Transportation has announced that the Build America Bureau provided a US$1.05 billion low-interest loan to Capital Beltway Express, LLC. The loan will refinance an existing loan for the Capital Beltway express lanes and construction of a northern extension called the 495 NEXT Project. Capital Beltway Express LLC is a joint venture of Fluor and Transurban.

There are currently 14 miles of tolled express lanes (two in each direction) on Interstate 495 (Capital Beltway) in Fairfax County, Virginia. The 495 NEXT will extend the express lanes by 2.5 miles from the Dulles Access Road to the George Washington Memorial Parkway near the state line.
