SIOUX FALLS — Starting April 24, traffic on 41st Street in Sioux Falls will shift to one lane in each direction on the north side of the 41st Street bridge.

This traffic switch is part of the conversion of the intersection into its final configuration for the Diverging Diamond Interchange. Crews will continue to work on the north islands and prepare for the next phase of construction.

Motorists should be prepared for delays. Drivers are asked to be aware of construction workers and equipment, and to slow down through the work zone. Motorist should expect congestion, very slow speeds, and stopped traffic conditions during the closure.
