Louisiana traffic control documentation requirements
What Louisiana DOT asks a contractor to record about temporary traffic control, where that requirement comes from, and how strong the evidence behind it is.
What Louisiana requires
DOTD Standard Plan TTC-00(B) (rev. Feb 7, 2025): "Daily updates to the DTOE, Project Engineer and TMC operator (if applicable) will be required for all projects where active closures are in place. Weekly updates… for all ongoing lane closures." And: "Contractors are responsible for complying with all TTC standards."
Standard Plan is contract-binding via Section 713.
Source: DOTD Standard Plan TTC-00(B)How DTCD satisfies it
Daily Entries + Agency Messaging produce the "daily updates to the DTOE, Project Engineer and TMC operator" required by Standard Plan TTC-00(B) for projects with active closures. Multi-Format Export supports the weekly update reporting cadence. CWZ 1.0 feed integrates with LADOTD TMC systems for real-time closure status.
What DTCD adds beyond the requirement
- Auto-Capture Signs and Connected Devices automate the device-by-device log that DOTD inspectors verify
- AI safety analysis identifies compliance issues
- Real-time CWZ 1.0 feed feeds LADOTD's regional and statewide TMC operators automatically — replacing the explicit "updates to TMC operator" obligation with automated data flow
- Public Dashboard provides DTOE real-time visibility
Who this helps
Contractor: Standard Plan TTC-00(B) daily update obligation under Section 713 is satisfied automatically through real-time data flow. DOT: DTOE, Project Engineer, and TMC operators receive updates without manual reporting.
On federal-aid work, 23 CFR 630 Subparts J and K apply whatever Louisiana 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 Louisiana requirement on the generated PDF. Open a sample before deciding anything.

Draw the closure on a map and the builder reads the route, mileposts and county from Louisiana’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.

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 Louisiana compare:
| State | Citation | Evidence we have |
|---|---|---|
| Arkansas | Special Provision SS-604 (Inspection of Traffic Control Devices in Construction Zones) + ARDOT Doc Express Contract Submittal System | Contract-binding spec language |
| Mississippi | Special Provision No. 907-618-12 (Section 618 Maintenance of Traffic) | Contract-binding spec language |
| Texas | Item 502 (Barricades, Signs, and Traffic Handling) — General Notes | Contract-binding spec language |
