SIOUX FALLS, S.D. – On Monday, April 8, 2024, an inside median lane closure is planned for the northbound and southbound lanes of Interstate 29 from the 49th Street intersection to the 41st Street intersection. This lane closure will be in place for one week to allow crews to conduct maintenance work at 49th Street.

Over the next few months, crews will focus on finishing touches, site clean-up, and transitioning the intersection into an operational DDI.
