On the eve of Spring 2024, construction is set to resume on one of the busiest crossroads in Sioux Falls. The third phase of construction at 41st Street and Interstate 29 begins Monday, March 18.

The Diverging Diamond Interchange (DDI) project began in 2022 and is anticipated to be completed this summer.

As this project comes to a close the South Dakota Department of Transportation will focus on finishing touches, site clean-up, and transitioning the intersection into an operational DDI.

Starting Monday, March 18, traffic will shift to one lane in each direction on the south side of 41st Street from Terry Avenue to the bridge's east side. This will allow crews to work on updates to the north side of the bridge. Once the bridge work has been completed, crews will focus on building the first island near the southbound off-ramp.

Commuters are asked to use caution and reduce their speed while traveling through the construction area.
