Six inches of swift moving water is all it takes to sweep a vehicle off a roadway according to the Missouri Department of Transportation.
When any water covers the road, MoDoT stresses to find an alternate route because drivers may not know how deep the water is.
"It's one of those things that we do try to monitor. We want those roads open to the public as soon as we can get them open. And so it's just a matter of frequently checking and taking a peek at what's happening with the water. Is it going up, is it steady, is it on its way down," said MoDot are engineer, Michael Rinehart.
MoDoT updates their interactive map online, giving travelers information they need before hitting the road. Portions of the Tarkio, Platte, Missouri, and Nodaway rivers are expected to crest over the weekend.
Though with more rain in the forecast throughout the Labor Day weekend, river levels could rise once again.
