Chesapeake Bay Bridge Tunnel, VA
This project focused on replacing the fender system at the North Channel Bridge, part of the Chesapeake Bay Bridge Tunnel. The goal was to enhance the structural integrity and functionality of the fender system, thereby ensuring the safety and navigability of the bridge. Key tasks involved in the project included the removal of existing collars, which were disconnected and removed by divers from the partially submerged stainless steel friction collars on the 12-inch diameter cylinder piles. The removed friction collars were then retrieved and disposed of off-site. Additionally, the project required the demolition of the existing, decayed, and dilapidated creosote-treated timber fender system. New 12-inch by 24-inch diameter, 1.5-inch thick stainless steel friction collars were procured and fabricated. These new collars were installed at the correct elevation using a 300-ton crane barge and divers, ensuring that all bolts were tightened to the specified torque. Creosote-treated dimensional lumber was sourced for the new fender system, and modular sections of the timber fender system were prefabricated to expedite installation. Once the modular fender system was transported to the site, it was secured to the existing fender piles and friction collars. As part of the project, an access ladder, navigation lights, and a tide gauge were also installed.
