Texas Flagger Lane Closure Traffic Control Plan
On a two-lane, two-way road you close one lane and flaggers alternate both directions through the single open lane. That is MUTCD TA-10, and it is the most common work-zone setup in the country. Below are the computed dimensions for Texas at four posted speeds — taper, advance sign spacing, buffer, and device count.

Governing typical application: TA-10 — Lane Closure on a Two-Lane Road Using Flaggers. Assumptions: urban collector, 2 through lanes, 12 ft lanes, 12 ft lateral offset, 100 ft work space, short-term duration. Rule set MUTCD 11th Ed. + 50-state/DC adoption layer + ID/ACHD profiles, rule set 2026-08 rev 4.
| Posted speed | Taper length (one lane two way) | Advance signs A / B / C | Longitudinal buffer | Device spacing taper / tangent | Channelizing devices |
|---|---|---|---|---|---|
| 25 mph | 100 ft | 100 ft / 100 ft / 100 ft | 155 ft | 20 ft / 50 ft | 19 |
| 35 mph | 100 ft | 250 ft / 250 ft / 250 ft | 250 ft | 20 ft / 70 ft | 18 |
| 45 mph | 100 ft | 350 ft / 350 ft / 350 ft | 360 ft | 20 ft / 90 ft | 19 |
| 55 mph | 100 ft | 350 ft / 350 ft / 350 ft | 495 ft | 20 ft / 110 ft | 19 |
What applies in Texas
- Agency rule set
- State of Texas (MUTCD as adopted)
- MUTCD adoption
- Publishes its own state MUTCD (cross-checked against a second source)
- State manual
- Texas MUTCD (TMUTCD), published by TxDOT
Printed on every Texas sheet:
- Texas publishes its own MUTCD — the Texas MUTCD (TMUTCD), published by TxDOT; this sheet uses National MUTCD default values as a planning baseline — the state manual controls and must be checked before submittal.
This rule set holds no Texas-specific permit form, review time, or closure-hour restriction, so none is shown. Those are set by whoever owns the road — state DOT, county, city, or highway district — and have to come from them.
Governing citation: Texas — MUTCD adoption recorded as: state MUTCD published (Texas MUTCD (TMUTCD), published by TxDOT). Bucket taken from secondary compilations of 11th-Edition state MUTCD adoption current to mid-2026; FHWA’s own state adoption listing was unreachable from the build environment and has not been checked directly. Cross-checked against a second independent source. The TMUTCD is long-standing and separately published by TxDOT. Texas is this product’s stated expansion market (PLAN.md), so this profile is a priority for real per-state rule encoding. This rule set asserts no Texas-specific numeric requirement; adoption status best-effort — verify against FHWA’s state adoption listing (“MUTCD information by State”) and the state DOT before submittal.
Questions people actually ask
What does a flagger lane closure plan need in Texas?
The same Part 6 elements everywhere: advance warning signs at the table spacing for the setting and speed, a flagger symbol sign and a flagger station on each approach, a 100 ft one-lane two-way taper, a longitudinal buffer equal to the stopping sight distance, and channelizing devices at the tabulated spacing. Local requirements sit on top of that, not instead of it.
How many cones do I need?
The count in the table is what the geometry requires: taper devices at the taper spacing, tangent devices along the work space at the tangent spacing, plus the downstream termination. It scales with the length of your work space, so set the real length in the builder before you buy or load.
Do two flaggers need radios?
If they cannot see each other, they need a way to communicate — radios, a pilot car, or a traffic control signal. MUTCD does not let a flagger release traffic into a lane the other end has not cleared. Sight distance between stations is the thing to check before you set up.

It is based on the MUTCD 11th Edition Part 6 typical applications and the agency rule set selected above. It is not a certified, sealed, or professionally engineered document and has not been reviewed against actual field conditions at this site. It must be reviewed, adapted to field conditions, and approved by a qualified person — and, where required, by the permitting agency and/or a licensed Professional Engineer — before use.
