Why One Ship Can Destroy an Entire Bridge?

At 1:29 a.m. on March 26, 2024, a container ship with no power drifted into one pier of the Francis Scott Key Bridge in Baltimore. Thirty seconds later, half a mile of highway was in the river. How can one ship, moving about as fast as a jogger, bring down an entire bridge? We rebuilt the night in 3D to show the three things that decided it: the mass of the ship, the shape of the bridge, and the age of its protection. 0:00 One ship, one pier, thirty seconds 1:55 Four minutes in the dark 3:07 Why the whole truss fell 4:48 Protection built for the 1970s 7:36 One loose wire, and the new bridge Sources: NTSB preliminary report (May 2024) and final report (November 2025); NTSB safety recommendation on 68 bridges in 19 states (March 2025, full list via CBS News); U.S. Army Corps of Engineers (channel reopening, June 2024); Maryland Transportation Authority. 3D models (CC BY 4.0 unless noted, Sketchfab): "Container Ship" by RM02; "Tug Boat 02" by gogiart; "Bulk Carrier" by medialog; "A Full Container Ship" by Mixmamo.studio; "2020 Ford Explorer Marked-Police" and "Ford F250" by David_Holiday; "Construction Worker In High Visibility" by restore50; "Yellow semi-truck with trailer" by Chenzoss; "Saturn V" by Battle_Dude; "Boeing 747-8i" by AF267; "Gordie Howe International Bridge 3D" by Geopogo; "Hall anchor" by day9; "Iron Chain" by mrkamyar; "Thames Dolphin Mooring Structure" by artfletch; "Breakwater coast" by SKMT; "Barrier & Traffic Cone Pack" by Sabri Ayeş; "Street Lamp" by StratoArt; "Industry: Diesel Generator - R2" by adam-q-kane; "3 Phase Circuit Breaker" by bentalebahmed98; "Electric Cabinet / Schaltschrank" by stefano (CC BY-SA).
