A medical issue may be to blame for a Janesville woman injuring herself in a single-vehicle crash Friday evening in the Village of Egg Harbor. The accident occurred on Harbor School Road near Church Street shortly before 5:10 p.m. The woman was seen traveling westbound on Harbor School Road when she crossed over the centerline and into a ditch. She hit several small trees and brush while crossing a private driveway before her vehicle eventually stopped. No drug or alcohol use was suspected, but she did appear to be confused and disoriented following the crash. The woman was transported to Door County Medical Center to be treated for possible injuries. She was cited for failing to keep her vehicle under control. As a result of the crash, one lane of Church Road was closed for over an hour while crews investigated and cleaned up after the crash. The roadway reopened at approximately 6:30 p.m.
