A semi truck hauling U.S. Postal Service mail on eastbound I-94 near Hudson caught fire at 8:19 a.m. on Tuesday, Dec. 13, and was destroyed, according to a press release from the Wisconsin State Patrol.
Roberts Fire Department, River Falls Fire Department, United Fire Department, St. Croix Sheriff’s Department and the St. Croix County Highway Department responded, finding the semi tractor fully engulfed and spreading into the trailer. The driver was not injured, but eastbound traffic was rerouted until the scene was cleared at 12:46 p.m.
A U.S. postal inspector was sent to assist with the cleanup and security of the mail. The truck was operated by Navigation Group Inc., of Downers Grove, Ill.
While many northwestern Wisconsin post offices are serviced by Twin Cities sorting hubs, it was not clear if any area mail was on the truck. Messages for the USPS were not returned as of press time on Dec. 13.
