A Milton man was killed Tuesday morning when his pickup truck rear-ended another pickup that had rear-ended a semi and become disabled on Interstate 39-90 near Janesville, the State Patrol reported.

The crash happened at about 5 a.m. near mile marker 177 and kept the southbound lanes closed until shortly after 9 a.m., according to a State Patrol news release.

The incident started when a 2017 Ford F350 pickup rear-ended a 2016 Freightliner semi and continued driving until it became disabled in the left lane. A 2005 Chevrolet Silverado then rear-ended the Ford, blocking both southbound lanes and one northbound lane for a time due to debris.
