Just after 1:00 p.m. today, a rollover accident on U.S. Highway 41 near Oshkosh closed all northbound lanes of U.S. 41. The car accident brought emergency crews streaming in from the City of Oshkosh, the Town of Oshkosh, the Town of Omro and Winnebago County.
Details from the car accident are still unclear, but emergency radio reports indicated that at least one occupant may have been ejected from the vehicle, sustaining serious injuries. Law enforcement officials have not yet determined what may have caused the rollover, which occurred just south of County trunk highway Y north of Oshkosh.
Rollover accidents can have several causes, including faulty design, driver error or simple physics. In the case of SUVs and passenger vans, the high center of gravity of the vehicles makes them particularly susceptible to rolling over after a collision or on uneven roads. Depending on the details of the crash, that high center of gravity may be found to have been a factor in the accident.
While the car accident debris was cleared and any injured people were taken to hospitals for treatment, law enforcement officials redirected traffic off of northbound U.S. 41. An accident investigation is underway, so the northbound lanes of U.S. 41 could be closed for several hours. A check of WDOT's Regional Traffic Incident Alert System around 4:00 p.m. showed the section of U.S. 41 from approximately Highway Z south of Oshkosh to Highway Y north of the town was still closed.
The police have not yet released any details about the accident or the seriousness of the injuries.
