Both lanes of Interstate 80 westbound were blocked for at least one-half hour early this morning, as fire crews from Walnut and Marne worked to extinguish a semi tractor-trailer that was engulfed in flames. Marne fire was called to assist Walnut Fire on I-80 westbound at mile marker 48, at around 1:25-a.m.

Deputies from Cass and Pottawattamie Counties helped to block the entrance and exit ramp and reroute westbound traffic to Marne at Exit 51, then west and back north to the interstate. There were no reports of injuries, and no other details available early today.
