Roads in western Iowa that were already partially to mostly-covered with snow, are also said to have a sheet of ice underneath the snow cover in some spots. Several vehicles have spun off into the median or ditches across I-80 and I-29, including at least four semi’s, but no injuries have been reported. The DOT’s 511ia.org website shows Travel is NOT ADVISED on I-80 from Highway 25 east to Des Moines, Highway 169 from Highway 92 north to Highway 30, U-S Highway 6 from Des Moines to Adel, and parts of Highway 141 in central Iowa.
