Iowa DOT News Release

Flooding closes additional Iowa roads

Posted on: August 11, 2010

AMES, Iowa - Aug. 11, 2010 – 9:30- a.m. update – Additional major highways are closed due to flooding in central Iowa, according to the Iowa Department of Transportation (DOT). Many county roads and city streets are also closed in the counties covered by the National Weather Service flood warnings.

Excessive runoff from heavy rainfall overnight is expected to continue to cause flooding of roadways in many parts of the state. Record flooding is forecast along portions of the South Skunk River from the Ames area to below Colfax. This is a particularly dangerous situation and travelers need to exercise additional caution in these areas. Flooding has already resulted in the closure of U.S. 30 and southbound I-35 near Ames.

Iowans are urged to continue to closely monitor conditions and never enter a water-covered roadway. If you encounter a flooded area, turn around – don’t drown.

For weather and other emergency information, stay tuned to NOAA weather radio or your local radio and TV stations.

Emergency response and recovery operations

The Iowa DOT is continuing to perform emergency response and recovery missions received through the Iowa Department of Public Defense’s Iowa Homeland Security and Emergency Management Division. On Thursday, Aug. 12, the Iowa DOT will have a dump truck in Whiting to assist with debris removal. The work is expected to take approximately one day.
