SIOUX FALLS — The public is invited to an educational open house to learn about the Diverging Diamond Interchange that is being built at the intersection of 41st Street and Interstate 29 in Sioux Falls.

Construction began on the DDI in 2022. The DDI configuration will be in place at the end of May. Additional landscaping and concrete work on the islands will be completed this summer.

The open house will be from 4 to 7 p.m. May 22 in the former Verizon store at The Empire Mall,  5000 W. Empire Pl. Individuals can enter through the door on the left-side of the food court canopy outside or directly left of the food court entrance inside. Information about how to navigate the DDI and a walkable demonstration mat will be available. The project team will be available to answer questions.

This will be the second operational DDI in South Dakota. Construction on others are underway throughout the state. The diverging diamond was chosen because of its safety features, along with the greater capacity and efficiency that it provides for the traveling public. It will reduce the conflict of left-hand turn movements and meet the needs of all road users to accommodate large trucks, pedestrians and bicyclists.
