Chesapeake Bay, VA – After traveling with more than 6,300 feet, the tunnel boring machine called “Chessie” fully fulfilled its task of excavating what is planned to become a new space on the CHESAPEAKE BAY Bridge (CBBT).
Shsie samples to the receiving pit on two islands on Monday, January 27th. According to CBBT, the work was then paused to allow the contractors to remove the trimming supports and steel beams that separate the shahs from the receiving pit. Once completely through, Chesi came out of the pit on Wednesday.
The already completely bored tunnel, known as the parallel tunnel of the thimble, is planned to be used for two new traffic lanes to the south between the east coast and the continental Virginia. The existing tunnel will be used for traffic in the north. The expansion is aimed at increasing the safety and efficiency of the trip to and from the delmar. The completion of the project is expected in early 2028.
“Now that her work is full, shed will be out of operation and demobilized by the Thimble Shoal parallel tunnel project,” CBBT officials said. “[Contractors] It will then start constructing the roadway inside the tunnel, installing electrical/mechanical systems and constructing supporting buildings. “
