I-66/Route 15 Interchange Reconstruction
Virginia DOT

This project reconstructed the Interstate 66 (I-66) / Route 15 interchange in Prince William County, Virginia, to relieve congestion, enhance public safety, improve operations, bolster capacity and accommodate forecasted traffic demand in the project area. It redesigned the interchange as a Diverging Diamond Interchange (DDI) — the first of its kind in the region — to best accommodate the projected traffic volumes as well as critical pedestrian movements in the interchange area.
