A fire that destroyed a pickup truck and the trailer it was towing Saturday near Marengo is under investigation, according to officials.

The car and two motorcycles that were inside the trailer are a total loss, according to the Marengo Fire & Rescue District.

Firefighters were called about 4:50 p.m. to the 18700 block of Route 176 in unincorporated Marengo for a report of a vehicle on fire, according to a news release.

At the scene, firefighters found a pickup truck and a 24-foot enclosed trailer in heavy fire conditions. Crews worked to put out the blaze and prevent it from spreading further into the truck cab, according to the release.

Route 176 was closed in both directions for about an hour while crews were on-scene.
