Interstate 29, is now open to traffic in southeastern South Dakota, state officials say. The interstate was closed at noon on Thursday so a levee could be constructed at Exit 4. The levee was a protective measure against rising waters of the Big Sioux River. The river crested early Friday morning below the level forecast earlier, and water didn’t reach the I-29 roadway.

Motorists are reminded there is still flooding on some state and local roads and should not drive through rushing or standing water as the roadway may be washed out underneath. Travelers are urged to visit www.safetravelusa.com/sd or call 511 to check the latest road conditions in their area
