The fire broke out shortly after 11 a.m. Monday, when the truck overturned on the Route 90 on-ramp to Route 130 in Pennsauken.
Firefighters began dousing the truck n with foam around noon, and it appeared to be out 10 minutes later, but it then reignited. Firefighters had it mostly under control again by 12:20 p.m.
The smoke could be seen 5 miles away in downtown Philadelphia.
Nearby homes are being evacuated as a precaution, and traffic is being diverted.
Authorities say the driver got out of the vehicle.
It’s not clear what caused the truck to overturn.
