    "summary": "On the afternoon of March 15, 2018, a 174-foot, roughly 950-ton concrete pedestrian bridge under construction at the edge of FIU's Modesto A. Maidique Campus [collapsed onto eight lanes of Southwest 8th Street](https://en.wikipedia.org/wiki/Florida_International_University_pedestrian_bridge_collapse), crushing vehicles stopped at a red light. The [National Transportation Safety Board](https://www.ntsb.gov/investigations/AccidentReports/Reports/HAR1902.pdf) found six people died and ten were injured, with the probable cause traced to design load-and-capacity calculation errors by the bridge engineers.",
    "outcome": "Six people were killed (one construction worker and five motorists) and ten injured. FIU directed the campus community to avoid SW 8th Street and the bridge area while a massive search-and-rescue and recovery operation unfolded. The span had been installed only five days earlier on March 10, 2018, and cracking had been reported before the collapse.",

  "context": "FIU's Modesto A. Maidique Campus sits beside the eight-lane SW 8th Street (Tamiami Trail / US-41), and the [FIU-Sweetwater UniversityCity Bridge](https://en.wikipedia.org/wiki/Florida_International_University_pedestrian_bridge_collapse) was being built to let students cross safely after a student had been killed crossing the road in 2017. The main span was installed using accelerated bridge construction on March 10, 2018, and collapsed five days later at about 1:46 PM EDT on March 15. The [NTSB final report](https://www.ntsb.gov/investigations/AccidentReports/Reports/HAR1902.pdf) determined the probable cause was load-and-capacity calculation errors by FIGG Bridge Engineers, with inadequate peer review by Louis Berger, and faulted the failure to close the road or shore the structure after significant cracking was observed days earlier. [NBC 6 South Florida](https://www.nbcmiami.com/news/local/5-years-later-fiu-bridge-collapse-remembered/2993692/) later reported the collapse killed six and injured ten, and litigation produced a collective settlement of more than $100 million. FIU's emergency notifications during the event focused on closing and clearing the SW 8th Street corridor while search-and-recovery teams worked through the rubble.",
  "keyFindings": [
    "A 174-foot, ~950-ton concrete span collapsed at roughly 1:46 PM EDT on March 15, 2018, just five days after installation, killing six and injuring ten",
    "The NTSB traced the probable cause to design load-and-capacity calculation errors and inadequate peer review, with a failure to close the road after cracking was observed",
    "FIU's notifications functioned as perimeter and community warnings for a structure that failed onto a state highway, not a purely internal campus hazard",
    "The verbatim initial Panther Alert text was confirmed from PantherNOW as 'Police activity in the area' -- notably not mentioning 'bridge collapse,' likely because the full scope was still being assessed when the alert was sent at 2:08 PM EDT"
