Officials reopen I-29 in southeast South Dakota

A section of Interstate 29 closed by flooding has reopened.

The Department of Transportation said a roughly 20-mile stretch in the southeastern corner of the state reopened to traffic Tuesday afternoon.

The interstate from North Sioux City to the Vermillion exit was closed since Sunday due to floodwaters.

Heavy rain doused most of southeast South Dakota late last week, resulting in flooded homes as well as many washed-out roads. While the interstate is back open, the state's 511 road conditions map shows many routes are still closed as of Tuesday. Floodwaters also washed out a railroad bridge in North Sioux City.

Some of the worst damage was caused by flooding on the Big Sioux River, which crested at a record-high level Sunday. That included serious flooding in the area surrounding McCook Lake in Union County, where many homes were destroyed.
