This week marks a milestone in the Elizabeth River Tunnel project in Virginia. The project is one of the largest infrastructure projects occurring in the U.S. right now. It will place a two lane tunnel next to an existing tunnel connecting Norfolk and Portsmouth, Virginia and thus double the tunnels capacity and reduce commute times. SKW Contractors team, a joint venture between Skanska, Kiewit, and Weeks Marine, are overseeing the public-private partnership project and are responsible for submersing eleven 16,000-ton hollow concrete elements into a special trench at the bottom of the Elizabeth River.
Operating since April 1964, Chesapeake Bay Bridge-Tunnel functions both as a bridge and a tunnel, as its name implies. After the $200 million structure's completion, the American Society of Civil Engineers named it "one of the seven engineering wonders of the modern world."
