Norfolk–Portsmouth Bridge–Tunnel, Underwater tunnel system in Norfolk, United States.
The Norfolk-Portsmouth Bridge-Tunnel consists of two parallel passages running beneath the Elizabeth River to link Norfolk and Portsmouth. Each tube carries traffic in one direction, providing a major vehicle crossing between the two cities.
The first tube opened in 1952 as Virginia's initial underwater crossing for vehicles. A second passage was constructed in 1987 to separate traffic flows by direction.
The tunnel system supports the transportation needs of the Hampton Roads region, connecting residential areas, business districts, and the largest naval base.
Height and width restrictions apply to all vehicles using this crossing, which affects tall trucks and oversized loads. Watch for posted limits at the entrance and proceed carefully through the passage.
The tunnel complex handles over three million vehicles monthly, operating with variable toll rates based on time periods and payment methods.
