NORFOLK, Va. (AP) - Some of the world's most sophisticated tunnel technology will be used to expand the Hampton Roads Bridge-Tunnel.
The Daily Press reported Thursday that contractors will use a massive machine to dig through the soil under Hampton Roads Harbor.
The digging will be a change from the previous method used to build or expand bridge tunnels in coastal Virginia. That method involved submersing prefabricated pieces of tunnel into a trench.
Contractors will add a new bridge-tunnel parallel to the existing ones that carry Interstate 64 from Norfolk to Hampton.
The project will accommodate more traffic and will cost $3 billion-plus. The state expects to choose a contractor for the project early next year.
