Moving Midtown Tunnel

Today’s the big day: our SKW Constructors team has begun the process of moving the first six of 11 concrete tunnel elements from the Baltimore location where they were cast to southeastern Virginia, where they will become part of the expanded Midtown Tunnel, the centerpiece of the $2.1 billion Elizabeth River Tunnels project. These giants – each 350 feet long and 16,000 tons – will be towed 220 miles down the Chesapeake Bay.

Early this morning, the process began by flooding the dry dock at the casting site. Once buoyant, the elements were moved out of the dry dock and temporarily moored in Baltimore harbor for final outfitting ahead of their journey.

Once the elements are ready to go, likely Tuesday morning, tugboats will tow them one at a time down the Chesapeake Bay, a slow-going process that we expect to take four- to seven-days per element, up to about seven weeks in total. Here is a map of that route:

If you’re local to this project, a great vantage point to watch the elements is on Island One and the Sea Gull Fishing Pier of the Chesapeake Bay Bridge-Tunnel, built in part by another Skanska consortium. Please share any photos you get of the elements in transit by tweeting them with the tag #MovingMidtown.
