A 44-year-old Manitowoc woman died, and two Sturgeon Bay residents were transported to the hospital as the result of a single-vehicle traffic accident on Sunday afternoon. At approximately 2:40 p.m., the vehicle was traveling west on Green Bay Road (STH 42/57) near Douglas Avenue when witnesses say it drifted to the right, went over the curb, and slammed into a brick retention wall. The driver, a 38-year-old Sturgeon Bay man, and the back-seat passenger, a 16-year-old Sturgeon Bay girl, were seriously injured in the accident and were taken to the hospital, where they are listed in critical condition. The woman, who was riding in the front passenger seat, was pronounced dead at the scene. The outside lane of the roadway was closed until just after 8 p.m. while the accident was being investigated. Traffic was still able to pass through on the inside lane. The Sturgeon Bay Police Department received assistance from the Door County Sheriff’s Department, the Sturgeon Bay Fire Department, Door County Emergency Medical Services, the Brown County Medical Examiner’s Office, and the Wisconsin State Patrol Accident Reconstruction Team all assisted in the response. Eagle III and Theda Care emergency heliport were also called for medical transportation. No other information is being released while law enforcement agencies complete their investigation.
