INDIANAPOLIS (WISH) - An Indiana Department of Transportation truck went up in flames Monday morning after striking a mattress in the middle of the highway.

A natural gas line on the truck was ruptured by the collision, sparking the fire that sent dark smoke into the area on the west side.

Southbound lanes of Interstate 465 were closed near Sam Jones Expressway but have since reopened.

Wayne Township Fire Department officials said no injuries were reported, despite two cars colliding near the incident.
