UPDATE: 9:30 a.m.: It's been five hours since a semi jack-knifed on northbound I-41 near Wrightstown, and major backups are reported with traffic at a stand still nearly back to Appleton.
Crews reopened the right lane at 8 a.m., but drivers currently stuck in traffic recommend avoiding the area until the Department of Transportation gives the all clear, as the left lane remains closed while crews work on guard rail repairs.
The jack-knifed semi initially closed both northbound lanes on I-41 on the county line between Outagamie and Brown counties near Wrightstown.
Traffic was being diverted off at County Road U, then re-entering back on County U.
