Brown County Sheriff's deputies are investigating a one car crash in the Village of Wrightstown.
It happened around 9:50 p.m. Tuesday on County HWY ZZ west of Mallard Road.
Deputies say the male driver was headed north on HWY ZZ when he lost control of his van on the icy roadway, went off the shoulder and into the ditch, striking trees.
The driver was taken to a Green Bay hospital with serious injuries.
Deputies say the driver was not wearing his seatbelt and alcohol does appear to be a factor.
