Crews with the Missouri Department of Transportation completed work on Route 141 under Interstate 44 in Valley Park. The intersection had been closed since April 30 due to floodwaters.
According to MoDOT, the floodwater receded early Monday but because of the depth of the water crews had to do some work to get the road ready for traffic.
The crews had to repair pavement and damaged walls, replace signal equipment, clean and restripe the roadway, and remove other debris.
Residents who take 141 were relieved MoDOT was able to get that work done fairly quickly. They said for over a week, a typical drive to work has taken double the amount of time.
More than a hundred roads were closed in the St. Louis area last week after days of heavy rainfall caused mass flooding.
