All lanes of Route 422 westbound in Collegeville, Pennsylvania, were closed Tuesday morning into the evening after a tractor-trailer caught fire, officials said.

The fire broke out around 8 a.m., the Upper Providence Township Department of Fire and Emergency Services said on Facebook. The closure was near where Route 422 crosses Route 29 in Montgomery County.

When crews arrived, they found a tractor-trailer with smoke coming from it. The Big Lots truck was found to be hauling "mixed-use electronic materials," the department's post said.

An Upper Providence Township official said the cloud of smoke has since dissipated.

Drivers were urged to avoid the area. The highway partially reopened in Upper Providence Township at around 6 p.m., an estimated 10 hours after the truck caught fire. 

Traffic from westbound Route 422 was diverted onto southbound Route 29. The entrance to 422 westbound from Route 29 was also closed.
