RUTHERFORD COUNTY, Tenn. (WKRN) – An overturned tractor-trailer hauling toxic chemicals closed Interstate 24 in both directions and a shelter-in-place was ordered by Rutherford County officials early Wednesday morning.

The crash occurred in the westbound lanes of I-24 near the Epps Mills Road exit around 3 a.m.

The office of Rutherford County Emergency Management initially asked all residents and motorists to stay clear of the area citing HAZMAT concerns but later asked all residents of Buchanan Estates to evacuate the area.

Officials are preparing to pour water on the fire, which will create a toxic cloud.

The hazmat plume extends about a mile southward from the crash site and winds are spreading the plume southward.

Roads affected include Epps Mill Road, Miller Road, Capitol Way, Rankin Road, Aldridge Road and near the Dollar General store.

Residents were asked to stay indoors, turn off all HVAC heat and air units and bring all pets inside.

Officials with the Tennessee Highway Patrol told News 2 the semi was hauling chlorine-based pool chemicals.

The crash involved two tractor-trailers and one driver was transported to Saint Thomas Rutherford hospital with non-life threatening injuries.

A spokesman with Rutherford County Schools said the hazardous materials fire is not expected to affect any schools directly but parents in the affected area should follow the instructions of the emergency personnel.

The district released a statement addressing bus routes:

Bus routes will not be run at this time in those areas affected by the sheltering procedures, and as such, students should not be left at bus stops if your neighborhood has been instructed to take shelter.

The school district will release additional information, as needed, concerning schools or bus routes. No schools are being closed at this time because of the hazardous materials fire in the Epps Mill Road area, under the recommendation of emergency response officials.

The Tennessee Department of Transportation estimates the roadway to reopen around 8 a.m. but it could extend longer.
