A small mudslide occurred on Summit Street in Alton and has worsened with the constant rainfall.

The southbound lanes of US 67 on the Clark Bridge are now closed to traffic heading into Missouri following an evacuation order issued by the Mayor of West Alton William Richter and the Rivers Pointe Fire Protection District.

Sunday afternoon, a small mudslide was reported on Summit Street in Alton. Due to the continuous rainfall that has fallen in the area and instability of the earth beneath the road, the concave formed on the brick road has worsened since it first began. Signs placed by the city have since fallen into the gap left from the mudslide and has descended down the hill.

With the help of IDOT, the Grafton Police Department has closed Route 100 near Jersey State Bank due to the rising waters. Locations on the left side of the road, like the Hawg Pit Restaurant, are currently taking on water.
