GALLERY: Iowa State Patrol asks drivers to stay off roads until midnight
Crashes effectively closing many highways across state
Highway officials in Iowa are warning drivers to stay off all roads until midnight.
The state Department of Transportation says it is extending a Wednesday night warning issued to drivers. It was set to expire Thursday at noon.
Annette Dunn, a spokeswoman with the DOT's Iowa Highway Division, says there are numerous car accidents along state highways. A 25-car crash along Interstate 35 in Clarion in northern Iowa has left one dead.
Dunn says some people may be tempted to drive because it's daylight. But she says people need to stay off the roads, including secondary ones, as poor visibility, blowing and snow drifts continue.
