How this desk works (below the article)
I-229 near Western Avenue is scheduled for bridge construction, grading and paving in both directions.
Work includes bridge construction, grading, and paving with lanes reduced to 2, speed limit 55 mph, traffic routed to opposing lanes, and truck speed limit 55 mph until further notice. I-229 northbound On and Off Ramps Are Closed at Exit 4 for the 2026 Construction Season. The project includes the reconstruction of exit 4 (Cliff Avenue) with added lighting, signals, and mainline Interstate work. The Interchange will be reconstructed as a Single Point Urban Interchange. This project includes two structure replacements. I-229 at Minnesota Avenue will have shoulder widening and a temporary bridge installed for a future project.
The listed work zone runs from half a mile north of the Western Avenue exit (Exit 2) to a quarter mile south of East Twenty-sixth Street-Exit 5, near milepost 4. The work is listed from 7 a.m. MDT (8 a.m. CDT) Monday, March 30, 2026, with no end date, which is how work scheduled until further notice is listed. The listing does not say which time zone applies, so both are given.
The project has its own page: dot.sd.gov/construction-projects/mitchell-region/sioux-falls-area/interstate-229-exit-4-cliff-ave-reconstruction/.
Plans change with weather and crews' progress; the South Dakota Department of Transportation has the latest at SD511.
