U.S. should be proactive on infrastructure updates; bridge collapse from massive cargo ship hit could be considered a failure of imagination on the part of bridge authority / DOTs
Engineers ask if Baltimore’s Key Bridge piers could have been better protected

Many bridges similar to Baltimore’s Key Bridge are protected by barriers designed to prevent or reduce the impact when vessels collide with piers. Such installations include cable systems, po…
