The Hampton Roads Bridge–Tunnel (HRBT) is a 3.5-mile-long (5.6 km) Hampton Roads crossing for Interstate 64 (I-64) and US Route 60 (US 60). It is a four-lane facility comprising bridges, trestles, artificial islands, and tunnels under the main shipping channels for Hampton Roads harbor in the southeastern portion of Virginia in the United States.

Hampton Roads is the name of both a body of water in the United States that serves as a wide channel for the James, Nansemond, and Elizabeth rivers between Old Point Comfort and Sewell's Point near where the Chesapeake Bay flows into the Atlantic Ocean, and the surrounding metropolitan region located in the southeastern Virginia and northeastern North Carolina portions of the Tidewater Region.
