What Montana requires

Documented requirement

MDT guidance says: “A daily project diary shall be kept detailing the project traffic control activities…” and provides temporary traffic-control device quality/inspection expectations.

How solid is this? Montana is documented from a high-confidence agency source, linked above, but we have not yet verified contract-binding specification language the way we have for the states in the full analysis. What governs your job is your contract and its special provisions — check them. This page is a stub until that verification is done, and it is deliberately excluded from search results so it cannot pass itself off as more than it is.

On federal-aid work, 23 CFR 630 Subparts J and K apply whatever Montana specifies, with a compliance date of December 31, 2026 — the federal floor, explained. And after an incident the questions come from the incident, not the specification: 105 published judicial matters on that.

DTCD produces this record from the drive-through itself, and names the controlling Montana requirement on the generated PDF. Open a sample before deciding anything.

Filing a work-zone request in Montana?

Draw the closure on a map and the builder reads the route, mileposts and county from Montana’s own public GIS, checks bridge clearance on the route and the detour, and exports a WZDx feature, a PDF or an email. It runs in the browser — nothing is submitted or stored.

What changes at the Montana state line

Crews rarely work one state, and the record a neighbouring DOT expects is often named differently and cited somewhere else entirely. Here is how the states bordering Montana compare:

State	Citation	Evidence we have
Idaho	Not yet verified	Agency source, high confidence
North Dakota	Not yet verified	Agency source, high confidence
South Dakota	Not yet verified	Agency source, medium confidence
Wyoming	Section 703.4.2 (Documentation)	Contract-binding spec language
