SIOUX CITY, Iowa – March 8, 2023 –  If you are driving on U.S. 71 in the Iowa Lakes Region (Arnolds Park and Okoboji) this spring you may notice some construction work. The first phase is expected to begin on March 13 from Okoboji Grove Road in Okoboji through Okoboji View Avenue in Okoboji. There will be daytime lane closures in the first week of this phase.

Starting March 20, traffic will be routed to a detour that uses Iowa 9 and Iowa 86. Weather permitting, this work should wrap up on May 25.
