  "bodyMd": "**Road work: bridge construction, grading, paving** is listed at I-229 from 0.25 mile south of Minnesota Avenue-Sioux Falls-Exit 3 to 0.50 mile south of East 26th Street-Sioux Falls-Exit 5, according to the South Dakota Department of Transportation's traveller-information feed.\n\nThe feed gives the route as I-229, the reference milepost as 4.460 and the affected direction as Both Directions.\n\nThe feed publishes a listed start of Sept. 22, 2026, 6:52 a.m. MDT / 7:52 a.m. CDT and no listed end — the feed publishes none for this record, which is how it represents work scheduled until further notice. Each is one instant shown in both of South Dakota's zones — Mountain first, Central second; they are the same moment. The feed names a route and not a zone, so 605Buzz does not pick one for you.\n\nWhether this work is currently underway is not stated in this text: it depends on the time you are reading, and the department is the authority.\n\nThe feed publishes coordinates of 43.51147577, -96.72727818 for this record. Those are the department's own figures, reproduced as published; 605Buzz does not geocode.\n\nThe department's own description of the work, reproduced without changes as published in the feed:\n\n> The following road construction project is in progress: 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.\n\nThat paragraph is the department's wording at the time this record was last read, including any dates or restrictions inside it.\n\nThe feed links [dot.sd.gov/construction-projects/mitchell-region/sioux-falls-area/interstate-229-exit-4-cliff-ave-reconstruction/](https://dot.sd.gov/construction-projects/mitchell-region/sioux-falls-area/interstate-229-exit-4-cliff-ave-reconstruction/) for this project.\n\n605Buzz has not independently verified conditions on this road. Schedules change with weather and contractor progress, and the department is the authority; check [SD511](https://www.sd511.org/) before travelling.",
