In Iowa, more than 50 U.S. highways and hundreds of smaller roads had to be closed due to the flooding.

While I-80 is again open in both directions, there are road closures and lane closures on other highways throughout the state.

Many of the state's roads, bridges and railways suffered major damage and there were significant traffic problems resulting from the temporary closure of sections of Interstate Highways 80 and 380, which connect Iowa City and Cedar Rapids. State officials described the widespread devastation as "unimaginable." Many of the closures will remain in place for an extended period of time due to damaged pavements.

Leading the state's response and recovery efforts for the Iowa transportation system is Iowa Department of Transportation Director Nancy J. Richardson. The Iowa Department of Transportation is posting the latest road closure information at www.511ia.org. There is also a special temporary phone number set up at 866-452-8510 for information on state highways.
