At approximately 1:30 p.m. EDT on March 15, 2018,[1] a 175-foot-long (53 m) section of a pedestrian bridge collapsed on the Tamiami Trail (U.S. Route 41).[2] The 320-foot-long (98 m) bridge was planned to connect the campus of Florida International University (FIU) in Miami-Dade County, Florida with Sweetwater, crossing six lanes of the Tamiami Trail just west of the intersection with Southwest 109th Avenue.[2] Erected only five days earlier on Saturday, March 10, it had not yet been opened to pedestrian traffic, and the school was on spring break at the time of collapse.[2] The section of the bridge that collapsed weighed 950 short tons (860 t) and fell onto several cars on the roadway below. The number of fatalities and injuries has not yet been determined.[2] At the time of the collapse the bridge was undergoing a stress test with multiple cars stopped at a traffic light under the span.[1][3][4] Eight cars are reported to have been crushed. At least one death has been reported.[5]

Bridge

The FIU–Sweetwater University City Bridge, located at the intersection of Tamiami Trail (Southwest 8th Street) and Southwest 109th Avenue, was planned to connect the FIU campus to residential neighborhoods in Sweetwater.[6] It was intended to improve pedestrian safety, as the busy intersection had been identified as a safety hazard and the site of fatal collisions.[7] The $14.2 million project was funded with a $19.4 million Transportation Investment Generating Economic Recovery (TIGER) grant from the United States Department of Transportation in 2013, along with state agencies.[8] The bridge itself cost $9 million to construct.[9]

The portion that collapsed was approximately the first half of the full span of a cable stayed bridge. [10] The central mast and ten cable stays had not yet been installed.

Construction on the bridge began in March 2016 and was scheduled to be completed in December 2018.[9][11] The bridge's prefabricated main span was assembled adjacent to the highway and constructed using Accelerated Bridge Construction (ABC), a technique developed at the university.[2] It was lifted into place on the morning of March 10, 2018, five days before the collapse, during a weekend closure of the highway.[12][13] The ABC method was touted to "...significantly reduce the risk to workers, walkers, drivers and minimized traffic disruptions for construction."[2] It was installed by Munilla Construction Management.[14]
