What New Hampshire requires

Documented requirement

NHDOT Work Zone Safety and Mobility Manual includes a dedicated “Work Zone Traffic Control Inspection Report” appendix and states the inspection process completes a “Work Zone Traffic Control Inspection” report for each inspection. This is not the phrase “traffic-control diary,” but it is a traffic-control-specific inspection/report record.

How solid is this? New Hampshire is documented from a medium-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 New Hampshire 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 New Hampshire requirement on the generated PDF. Open a sample before deciding anything.

Filing a work-zone request in New Hampshire?

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

State	Citation	Evidence we have
Maine	Not yet verified	Agency source, high confidence
Massachusetts	Not yet verified	Agency source, medium confidence
Vermont	Section 641 (Traffic Control)	Binding language identified
