After extracting more than 6300 feet. Under Thimble Shoal Channel, Chessie has officially completed her trip, successfully coming out of the host pit on two islands on January 29, 2025. The Minute has been stopped to allow the joint venture of the CEPEAKE (CTJV) tunnel, design -Pork performer for This project, to remove temporary reinforcing supports and steel beams that have been in place.

The yield resumed as chassis, tunnels through the rest of the receiving wall.

The completion of the extraction at Thimble Shoal Channel marks a significant moment for this project. Chessie, the tunnel boring machine designed and built by Herrenknecht specifically for this project, has removed approximately 500,000 cubic meters of YDS. Soil and installs nearly 10,000 concrete segments, each weighing 10 tonnes, as it began to produce in February 2023.

Now that her work is completed, shed will be out of operation and demobilized by the project for the parallel Thimble Shoal tunnel. The CTJV will then start constructing the roadway inside the tunnel, installing electrical/mechanical systems and building supporting buildings.

The Bridge of the Czech Czech Bridge is a vital transport connection connecting the peninsula to the continental part of Virginia Beach. The new parallel tunnel will significantly increase the safety and efficiency of this transport infrastructure, which welcomes more than four million vehicles every year. Once completed, the new tunnel will wear two lanes of traffic to the south, while the existing tunnel will wear two lanes of traffic to the north. The current project completion forecast is in early 2028.

Chesapeake Tunnel Action Venture (CTJV) is the design contractor for this project, consisting of Dragados USA and Schiavone Construction Company, LLC. The two sister companies are part of ACS Dragados from Spain, the world leader in underground construction, receiving over 550 underground projects and completing over 940 miles. of tunneling through all types of geological conditions.
