  • You can learn how learn more about procurement for the project on this page

Project NEXT is an extension of the 495 HOV/HOT Lanes (Express Lanes) in Fairfax County, Virginia.  As shown in the figure below, the project will extend along Interstate 495 (I-495) from the current northern terminus of the 495 Express Lanes near Old Dominion Drive (Route 738) to the vicinity of the George Washington Memorial Parkway (GWMP), and include improvements to the Dulles Toll Road and GWMP interchanges and the northbound general purpose lanes.  I-495 currently operates with four general purpose lanes in each direction along the project corridor.
                                                                                           
The primary objective of the project is to extend the 495 Express Lanes further north to provide additional capacity in the corridor, which will be available at no charge to HOV 3+ vehicles, and open to other authorized vehicles paying a toll.  This extension will be subject to the same operating rules and regulations as the existing 495 Express Lanes, and when complete, will operate as a single, fully-integrated 495 Express Lanes facility between the Springfield Interchange and the GWMP.
