Overview
- A box trailer hauling consumer fireworks ignited on northbound I‑75 just past the Ooltewah exit and the load became involved in the blaze, sending fireworks exploding across the roadway on Saturday evening.
- Tri‑Community Volunteer Fire Department led the response with Chattanooga crews providing mutual aid and emergency vehicles used southbound lanes to shuttle water to firefighters tackling the blaze.
- Authorities temporarily shut both northbound and southbound lanes to protect drivers and the southbound side reopened first while crews monitored hot spots and cleared the burned trailer from the road.
- No injuries were reported and dramatic videos and photos shared by the Chattanooga Fire Department show fireworks launching and exploding as crews fought the fire.
- Officials have not released a cause and investigators continue to review the incident, with local context noting that large shipments of consumer fireworks increase fire and transport risks ahead of the July 4th period.
