A multi-vehicle wreck shut down two lanes of I-75 northbound for several hours late Friday evening.
The accident happened around 4:30 p.m. near the Emery Road exit.
Knoxville police say a semi truck, two large utility trucks and three passenger vehicles were involved in the accident. One person was taken to UT Medical Center with non-life threatening injuries.
The Knoxville Fire Department haz mat team responded because diesel fuel was leaking from a ruptured fuel tank.
The lanes were closed for several hours during the investigation and clean up.
