HANNIBAL – Due to a deteriorating road surface, Route O in Warren County, between Route M south to Missouri Route 47 at Marthasville, remains closed to through traffic until further notice. Maintenance crews continue to repair the deteriorated roadway by removing the broken up pavement and placing rock. This work will continue until further notice, but will be dependent on the weather conditions.
Crews are installing additional “Rough Road” signs warning drivers conditions. Traffic should pay attention to all posted signs and drive for road conditions. The posted speed limit is 35 mph. In addition, motorcycles are advised to avoid travel on Warren County Route O at this time.
“Crews will continue to make repairs, but motorists should expect the restriction to local traffic only and the speed limit of 35 mph to remain,” said District Engineer Paula Gough.
