How this desk works (below the article)

I-29 near Sioux Falls is scheduled for bridge construction and grading in both directions.

Work includes bridge construction adjacent to the roadway and grading adjacent to the roadway until further notice. Construction of New 85th St & I29 Interchange. Current shoulder closures along I29 SB and I29 NB. Additional lane closure along the I229 SB to I29 SB ramp for construction of new bridge and construction traffic.

The listed work zone runs from a mile and a half south of the Interstate 229 junction at Sioux Falls (Exit 75) to the Interstate 229 junction at Sioux Falls (Exit 75), near milepost 75. The work is listed from 6:12 a.m. MDT (7:12 a.m. CDT) Wednesday, Sept. 23, 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/projects-studies/construction-projects/i-29-and-85th-street-interchange-in-sioux-falls/.

Plans change with weather and crews' progress; the South Dakota Department of Transportation has the latest at SD511.

How this desk works

Where this comes from

This listing comes from the South Dakota Department of Transportation's public traveller information, served through its vendor's content network. Neither host publishes a robots.txt or terms-of-use page, so no access directive exists either way; the department's own fields are reproduced with attribution, and no licence is claimed that nobody granted.

How the times are shown

The department publishes start and end as numeric timestamps, so each is shown as a clock reading in both of South Dakota's zones.

How the status is decided

Whether work is currently underway is not written into the article text, deliberately: it depends on when you are reading. It is worked out from the listed dates each time the page loads rather than stored as an answer that would go out of date without anyone noticing. The status at the top of the page is that calculation, not a claim the department made.

The department's description is put into plain words by fixed rules only: its standard opening line is replaced, times and dates are written the way people say them, and direction words lose their capitals mid-sentence. Nothing is added, and every number, place and time it gives is kept; a description in a shape those rules were not written for is quoted exactly as published. A detail inside it can be superseded without the surrounding fields changing.

Around this record

The records published so far include 10 road records from the South Dakota Department of Transportation within about 16 miles of this location with a listed start on or before this date. SDDOT published no end date for all of them, which is how the department represents work scheduled until further notice — whether those are current cannot be worked out from the records, and no guess is made. SD511 is the department's own live conditions service.

The records published so far include 1 other record within 5.0 miles of this location whose own record date is also this date. That counts only the published records, not everything happening nearby, and a record's date means different things by desk — a permit's is the day it was issued, an event's is the day it happens.

This section is assembled from other records already published and from arithmetic on the date above and on the coordinate this record's source published. It is not part of the filed record.
