Version history
Every published version of this article, newest first. Versions are append-only: a correction adds a row, it never rewrites history. Each version below states what changed against the version before it — which fields moved, and which body lines were added or removed.
The content hash is a SHA-256 fingerprint of that version's stored headline and body, computed when the version was written. Two versions with the same hash hold identical text; a changed hash proves the text moved. It is the tamper-evidence check — recompute it against an exported copy of a version and any silent edit shows up as a mismatch.
How we verify a hash — and how you can
Canonicalization: the hashed bytes are the version's stored headline, then the two characters ||, then the version's stored body markdown — UTF-8, SHA-256, lowercase hex. Nothing else is in the input: no normalization, re-wrapping or rendering is applied first, no trailing newline is added, and no other field (including the parent version's id) is mixed in.
Export a version's stored headline and body, join them with the two characters ||, and take the SHA-256 of the UTF-8 bytes. It must equal the hash printed beside that version. In a shell:
printf '%s' "HEADLINE||BODY" | shasum -a 256-

Version 3
Wording carried forward. 605Buzz changed its own wording of this page after the previous entry and before the next one. This entry records the page as it read just before the source’s change, so the next entry shows only the source’s change. It does not say whether the earlier wording was right or wrong.

- The listed work zone is at US-16A at the South Dakota 40 junction at Keystone, near milepost 34. The work is listed from 12:43 p.m. Mountain time (1:43 p.m. Central) Tuesday, Oct. 13, 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.

- **Restrictions: bridge construction** is listed at US-16A at Junction South Dakota 40-Keystone, according to the South Dakota Department of Transportation's traveller-information feed.
- The feed gives the route as US-16A, the reference milepost as 33.830 and the affected direction as Both Directions.
- The feed publishes a listed start of Oct. 13, 2026, 12:43 p.m. MDT / 1:43 p.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.
- Whether 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.
- The feed publishes coordinates of 43.89581722, -103.42328618 for this record. Those are the department's own figures, reproduced as published; 605Buzz does not geocode.
- The department's own description of the work, reproduced without changes as published in the feed:
- > Restrictions include: length limit 50 ft and width limit 12 ft until further notice. Road work will begin on September 8th 2026. Beginning October 5th the road will be closed to remove the structure. A detour route will be available.
- That paragraph is the department's wording at the time this record was last read, including any dates or restrictions inside it.
- The feed links [dot.sd.gov/construction-projects/rapid-city-region/custer-area/us-highway-16a-in-keystone/](https://dot.sd.gov/construction-projects/rapid-city-region/custer-area/us-highway-16a-in-keystone/) for this project.
- 605Buzz 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.
