I-87 back open after truck fire in Wake County

Traffic is flowing again Thursday night after a truck fire caused several delays in Wake County.

WRAL's traffic cameras captured a vehicle that appeared to be on fire on I-87 near Knightdale in Wake County.

Crews closed off all northbound lanes of I-87 as they attempt to put out the fire and clear the scene, but have since reopened a few of them. It is not clear what caused the vehicle to catch on fire.
