Sparks from bridge repair work rained down on boats beneath the I-40 Hernando de Soto Bridge near Mud Island in Memphis on Wednesday evening, triggering a dockside fire that sent thick, black smoke rolling over the riverfront and briefly left workers stranded roughly 90 feet above the water. Crews managed to contain the blaze, and city officials said no one was hurt.
According to officials, Arkansas Department of Transportation crews were repairing steel joints on the westbound side of the bridge when welding torches threw off sparks that dropped onto vessels moored below and ignited several boats. The Memphis Fire Department responded, knocked down the flames, and confirmed there were no injuries, according to FOX13 Memphis.
Hot-work risks and rules
Welding and similar "hot work" can throw slag and sparks far beyond the immediate work zone, which is exactly why the safety rulebook for these jobs is so strict. Industry standards call for a formal permit process, a designated fire watch, and careful removal or shielding of combustible materials in the area to keep stray sparks from finding fuel.
That framework, set out in NFPA guidance and echoed in federal safety rules, typically requires employers to clear or protect combustibles within a broad radius, assign a fire watch, and monitor the area after work wraps up, per NFPA 51B.
Emergency response and people on the bridge
Officials said four to five workers were briefly stuck on a suspended work platform about 90 feet above the river while the situation unfolded below. Crews were able to secure the workers, and the Memphis Fire Department brought the blaze under control as other personnel on site moved to secure nearby vessels and the work zone. Investigators are now reviewing the scene, officials told FOX13 Memphis.
Bridge repairs, traffic, and what to watch
The Hernando de Soto (I-40) bridge has been undergoing phased repair work this month, with alternating single-lane closures scheduled through June 11 to allow inspections and steel repairs, a local outlet reported. Drivers should be ready for periodic work windows while the project continues, and ARDOT posts updates at idrivearkansas.com and ardot.gov, per KAIT.
Officials have not yet released an estimate of damage to the boats. City and state agencies are expected to review worksite safeguards and hot-work procedures as part of any follow-up. We will update this story when officials release additional details.
