All lanes of Route 422 westbound in Collegeville, Pennsylvania, were closed Tuesday morning 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 is 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.
