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

It connects the historic Phoebus area of the independent city of Hampton near Fort Monroe on the Virginia Peninsula with Willoughby Spit in the city of Norfolk in South Hampton Roads, and is part of the Hampton Roads Beltway.

To ease the traffic pressure, the expansion of the I-64 Hampton Roads Bridge-Tunnel is extremely urgent, including changing four lanes to six lanes in both directions from the I-664 interchange to the I-564 interchange, with a new, three lane bridge tunnel built to carry traffic eastbound (Hampton to Norfolk).

The project’s estimated cost is $3.3 billion. The current project schedule anticipates an RFP in 2018, contract award in 2019, and completion in 2024.

Soil anchor has great effect on supporting and reinforcing projects. It combines drilling, grouting and anchoring together. Through corrosion prevention surface material, soil anchor can be used for permanent support.
