An Amazon semi-truck that caught fire was causing major delays on Interstate 80 in Placer County late Wednesday afternoon.

Caltrans said westbound I-80 just north of Applegate was reduced to one lane as crews worked to clear the big rig from the area.

As of around 3:30 p.m., Caltrans said the fire had been put out but there was no estimated time for the lanes to reopen.

A photo from the scene shows the rear end of the big rig with extensive fire damage and packages spilled out onto the side of the road.

The cause of the fire is not yet known.
