There are over 150 Diverging Diamond Interchanges in the United States with 80 more under construction. 3 of which are in South Dakota cities including Sioux Falls, Brandon, and Rapid City.

Construction began on the Sioux Falls DDI in 2022 and is near completion.

The current traffic pattern is in a more simplified DDI configuration with one lane in each direction over the bridge. All lanes of the DDI are anticipated to open at the end of June.

All on- and off-ramps are open except for westbound traffic on the northbound off-ramp.

Here is the latest update on the Sioux Falls Diverging Diamond Interchange at 41st and I-29...

• Permanent pavement marking will begin in mid-June.
• Installation of sidewalks across the 41st Street bridge has been completed; sidewalks will remain closed until other work is completed.

• Crews have completed installing walls around the center median.
• Crews are painting underneath the bridge.
• Crews are beginning the final touches and landscaping on the medians.
