Update at 1:40 p.m.
Both north and southbound lanes are open on US 41 but traffic is still slow. More information will be released as we get it in.
We have a crew on the way to an accident on State Road 41 near Plank Road, approximately three to four miles south of Vincennes.
Scanner traffic has indicated there is an accident with injury involving a car and a semi.
The northbound lane is backed up due to the road closure.
