Minnesota Spring Thaw Weight Restrictions

Six frost zones, each with a published start and end date. MnDOT announces changes at least three days ahead, which is what makes a several-hour poll comfortably fast enough.

What we do with it
Parsed into dated restriction rows.
Posting season
02-15 to 06-01 — MnDOT publishes both a start and an end date per frost zone before the season opens, and announces each at least three calendar days in advance. 2026's table ran Mar 3 (Metro/South/Southeast) to May 15 (North).
Polling cadence today
Outside Minnesota's posting window by 100 days — polled weekly, so an unscheduled restriction and a broken source are both found before the season opens.
If our copy goes stale
It errs toward missing a restriction posted since we last read it, because this source publishes a fixed end date that expires on its own.
