DES MOINES, Iowa (AP) — A winter storm is leaving wind-blown snow throughout Iowa and Nebraska, creating continued challenges for travelers. Many of the major road problems have been cleared, but the Iowa Department of Transportation and Nebraska Department of Roads say roads, bridges, overpasses and ramps remain slick in many locations. Numerous accidents, blockages, backups and jackknifed trucks have been reported throughout the day.

Persistent blowing snow over east-west roadways in open areas is the biggest concern because it causes glazing of roadway surfaces. Patchy slick spots can be encountered at any time. The Nebraska officials are telling evening and early morning travelers to turn off cruise control and use extreme caution because roads are packed with snow and icy.
