Cleanup underway in Alton and flooded river towns in Illinois
Crews cleaning up Southern Illinois roads that have been submerged for weeks or months beneath floodwaters are using fire hoses and snowplows to clear the roadways of mud, slime and debris.
As floodwater slowly creeps back into area rivers, workers with the Illinois Department of Transportation are starting the cleanup process while assessing the damage left behind.
IDOT Region 5 Operations Engineer Joseph Monroe said, so far, most of the damage has been erosion to the shoulders of roads.
“What we’re finding with the ones we’ve been able to reopen is a lot of shoulder erosion and erosion around culverts and other drainage structures,” Monroe said. “Most surfaces, thus far, have not been damaged as we originally feared.”
While submerged, floodwater acts as a lubricant for the pavement, loosening its bonds. As current, winds and even storms push the water around the surface, material may be pulled away from the sides of the road.
“The rock will typically just wash away,” he said, calling the problem fairly common. “We haven’t run into anything that has been out of the ordinary.”
For culverts constantly trying to equalize pressure, climbing and receding floodwater contributes to erosion in the same way.
There has been some surface damage in Grafton and Alton, two of the metro-east’s worst-hit areas for flooding. Monroe said mud was caked on so thick in some areas that workers needed a fire hose and snowplow to remove it.
In Michael, an area between the Mississippi and Illinois rivers north of Hardin, one road on a slope was moved 1,500 feet away from its original spot.
In most places, though, Monroe said damage won’t delay roads from being reopened. He said only time can tell the true extent of the damage.
“It’s nothing that will prohibit the road from being opened, but it is something we’ll have to address as time and workload allow,” he said.
As rivers continue to recede, more and more roads are being assessed and cleaned. Monroe said he is optimistic about the state of most of the uncovered roads. Roads that may be submerged until mid-July may be a different story.
“We have several roadways that remain under,” he said. “We’re optimistic that we won’t have anything significant but we don’t expect to see a significant fall in the river until next week.”
Monroe stressed that drivers should avoid roads that remain closed, even it it appears to be dry. Debris, slick mud, road repairs and more can make roadways dangerous, he said, urging drivers to respect barriers and detours.
