Authorities say more than 180 Missouri roads are closed because of flooding.

The Missouri State Department of Transportation says the closures include eastbound lanes of Interstate 70 in St. Charles County. Though both lanes closed Sunday because of rising flood waters, the westbound lanes reopened Monday morning.

Several bridges in southeastern Missouri counties also are closed because of flooding.

The National Weather Service said three to six inches of rain fell during the weekend, and up to four inches more is expected through Monday.
