Highway T-15 at the Red Rock Dam will be closed at times this week due to construction at the hydroelectric project site.

The county highway will be closed to traffic between the hours of 9 a.m. and 3 p.m. Monday through Wednesday. Joni Livingston with Missouri River Energy Services says the road closures will help ensure the safety of the public and workers during installation of a temporary earth retention structure on the downstream side. Message boards will be posted on both the Pella and Knoxville sides to remind drivers of the closures.
