All lanes of eastbound Highway 512 near Puyallup reopened around 7:30 a.m. Monday after a semitruck apparently scraped a bridge and erupted into flames, snarling the South Sound commute for hours.

Officials with the Washington state Department of Transportation tweeted that the 2 a.m. blaze near Portland Avenue East heavily affected westbound traffic as well. WSDOT urged drivers to delay trips through the area or find alternate routes.

Video from witnesses shows the flaming semi with at least two holes in the trailer, KOMO-TV reported.

Witnesses reported seeing the trailer hit a bridge and then burst into flames; the driver was reported to have escaped without serious injury, KOMO reported.
