Interstate 5 southbound was closed Saturday near milepost 192 at the OR 126-McKenzie Highway interchange as hazmat crews responded to spilled diesel from a burning garbage truck.

Authorities reported shortly after 2 p.m. that a southbound lane had reopened, allowing traffic to pass by the crash scene, but they warned drivers to slow down and use caution.

The fire started when a garbage truck caught fire in the southbound lane on Franklin Boulevard. Eugene Springfield Fire responded at 11:08 a.m. after dispatching Engine 4 from Springfield’s 5th and Centennial station, according to a statement from ESF.

The teams saw that the vehicle was completely engulfed in flames and the diesel tank was leaking fuel onto the road. The diesel spill raised concerns due to its proximity to the Willamette River, prompting ESF’s hazmat team at the Valley River station to assist.
