The state Transportation Department plans to close state Highway 44 west of the Platte-Winner bridge starting Tuesday so it can repair a landslide.

The closure from just west of the Missouri River bridge to Highway 1806 South will last at least 10 days and possibly up to 40 days.

The DOT says the road continues to slide and deteriorate because of a landslide brought on by heavy spring rain and runoff.

Alternate routes across the Missouri River include Interstate 90 at Chamberlain and U.S. Highway 18 at Pickstown.
