A 76-year-old Egg Harbor man was unsure what happened that caused him to crash his vehicle along State Highway 42/57 in Sturgeon Bay on Tuesday, damaging two mailboxes and sending him to the hospital along the way. The single-vehicle crash occurred before 7:30 a.m. after deputies were alerted to a reckless driver driving south on the highway. According to the incident report, witnesses saw the car swerving in the lanes before driving off the roadway. He hit two mailboxes before entering a ditch line, going airborne across a driveway, and coming to a rest. Deputies had to break a window in order to reach the driver, who was unresponsive when they arrived. Talking to the driver later in the day, he remembered going over the rumble strips and into the ditch before blacking out. The driver was taken to Door County Medical Center to be treated for possible injuries. The accident closed one of the southbound lanes of STH 42/57 for nearly an hour before it was fully open by 8:25 a.m.
