495 Express Lanes Northern Extension (495 NEXT) VA

Published by Hank Gottschalk

CP&P is producing several precast box culverts for the 495 NEXT project in Northern Virginia. One notable run is a Double Monolithic 10×10 Precast Box Culvert installed by Shirley Contracting Company. 30 each precast sections totaling over 150 linear feet with precast wing walls were used to extend an existing box culvert.

The I-495 Express Lanes Northern Extension (495 NEXT) project is a public-private partnership between the Commonwealth of  Virginia and Transurban that involves extending the 495 Express Lanes north by two-and-a-half miles from the Dulles Corridor to the George Washington Memorial Parkway interchanges near the American Legion Bridge.  This important initiative will provide congestion relief, add travel choices, improve travel reliability and enhance safety on a vital corridor in Northern Virginia and the larger region.  495 NEXT will provide new and improved express lanes connections at the Dulles Corridor and George Washington Memorial Parkway interchanges.

Construction kicked off on VDOT’s 495 NEXT project in March 2022, along with final project design. The extended 495 Express Lanes are expected to open in late 2025, with the project completed in 2026.
