The U.S. Army Corps of Engineers, Rock Island District, announces temporary single-lane road closures to Highway T15 across the Red Rock Dam beginning February 27. Closures will only be in effect Monday through Friday each week. The road will be fully open to traffic on the weekends during this period. Partial closures are expected to last five weeks and are necessary for preventive maintenance to the Red Rock Dam.  

Starting April 5, a full road closure to Highway T15 over Red Rock Dam is scheduled and will last through approximately May 30. During that time, a detour will be in place. Additional partial and full road closures may be needed through 2024 for rehabilitation projects on the dam.
