BROOKINGS — A blaze Friday involving a box truck on Interstate 29 caused an estimated $57,000 in damage, but no one was injured, according to the Brookings County Sheriff’s Office.

The incident occurred at 5:12 p.m. at mile marker 147 and involved a 2012 Dodge Ram 5500, Assistant Sheriff Scott Sebring wrote in the release. The damage estimated included the truck and its contents.

The truck’s driver and a passenger were traveling on I-29 when they heard an odd noise from the truck and pulled over to investigate, according to the release.
