Apparently, there was some warning that the bridge was failing because there are amateur videos showing roadway gaps and uplift followed by the actual collapse. Be careful when searching because there's a suspension bridge (which didn't collapse) that has the same or very similar name, Juscelino Kubitschek de Oliveira Bridge. See image of bridge here: https://www.folhadobico.com.br/wp-content/arquivo/2023/09/2-13.jpg The stains on the structure mid-span imply long-term lack of maintenance on the sixty-year-old bridge.
