EMERGENCY CLOSURE Route O Warren County to Through Traffic

HANNIBAL – Due to a deteriorating road surface, Route O in Warren County, between Route M south to Missouri Route 47 at Marthasville has been closed to through traffic until further notice. Both lanes are physically closed to all traffic south of Polston Lane.  “Local traffic is allowed; however, those who live near the physical closure will not be able to drive through this area,” explained Missouri Department of Transportation District Engineer Paula Gough.  She encourages drivers to refer to MoDOT’s online traveler map for alternate routes.

Over the last few months, Warren County Route O has been seeing an increase in truck traffic. This traffic, along with wet conditions and warmer temperatures, has caused significant roadway deterioration. Local residents are encouraged to pay attention to all posted signs and barricades and to drive for road conditions.  In addition, motorcycles are advised to avoid travel on Warren County Route O at this time.

“We ask that local residents pay attention to the signs posted and drive for road conditions,” said District Engineer Paula Gough.

Crews will begin making repairs beginning Friday, February 26th  to re-open the closed lanes, but motorists should expect the restriction to local traffic only to remain while additional repairs are made in the future.
