Idaho traffic control documentation requirements

What Idaho DOT asks a contractor to record about temporary traffic control, where that requirement comes from, and how strong the evidence behind it is.

What Idaho requires

Documented requirement

ITD Contract Administration Manual states the daily diary is covered in CMUG and identifies the person responsible for checking traffic control daily.

How solid is this? Idaho 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 Idaho 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 Idaho requirement on the generated PDF. Open a sample before deciding anything.

Filing a work-zone request in Idaho?

Draw the closure on a map and the builder reads the route, mileposts and county from Idaho’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 Idaho 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 Idaho compare:

State	Citation	Evidence we have
Montana	Not yet verified	Agency source, high confidence
Nevada	Section 624.03.06 (Traffic Control Supervisor)	Contract-binding spec language
Oregon	Section 00220 (Accommodations for Public Traffic) — TCS duties	Contract-binding spec language
Utah	Section 01554 (Traffic Control) — 1.5 Submittals and 1.9 Traffic Control Supervisor	Contract-binding spec language
Washington	Section 2-04.3(1)B (Traffic Control Supervisor)	Contract-binding spec language
Wyoming	Section 703.4.2 (Documentation)	Contract-binding spec language
