The Bridge That Defied Gravity#construction #engineering #infrastructure #foryoupage #Knowledge

Happy Thanksgiving from the NB SR 167 bridge in Pacific! We said crews would work 24 hours a day, seven days a week to get this bridge fixed, and we meant it.

Some shipyards use side launching, where the ship rolls sideways into the water. While it looks dramatic, it’s risky and can cause serious damage or even capsizing, especially for large ships. A more balanced option is
