The steel frame of the Francis Scott Key Bridge sits on top of the container ship Dali after the bridge collapsed on Tuesday. After the 1980 collision, he argued, more substantial dolphins or a fendering system should have been added to the Key Bridge. “You knock out one of the support posts, the entire bridge collapses.”The Key Bridge is hardly unique among large bridges in its age. Some other bridges that cross major shipping routes are designed with more extensive protections than the Key Bridge’s. In the wake of the Key Bridge collapse and with the rise of larger container ships, some experts said that engineers should reassess necessary bridge safety features.
