New York Multilane Lane Closure Traffic Control Plan
Close one lane of a four-or-more-lane, non-divided road and traffic merges past the work behind a taper and an arrow board — MUTCD TA-30. The merging taper is the long one, and it grows fast with speed. Here is what the engine computes for New York at 25, 35, 45, and 55 mph.

Governing typical application: TA-30 — Lane Closure on a Multilane Street. Assumptions: urban collector, 4 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 (merging) | Advance signs A / B / C | Longitudinal buffer | Device spacing taper / tangent | Channelizing devices |
|---|---|---|---|---|---|
| 25 mph | 125 ft | 100 ft / 100 ft / 100 ft | 155 ft | 25 ft / 50 ft | 18 |
| 35 mph | 245 ft | 250 ft / 250 ft / 250 ft | 250 ft | 35 ft / 70 ft | 18 |
| 45 mph | 540 ft | 350 ft / 350 ft / 350 ft | 360 ft | 45 ft / 90 ft | 24 |
| 55 mph | 660 ft | 350 ft / 350 ft / 350 ft | 495 ft | 55 ft / 110 ft | 23 |
What applies in New York
- Agency rule set
- State of New York (MUTCD as adopted)
- MUTCD adoption
- National MUTCD adopted with a state supplement (single secondary source — unconfirmed)
Printed on every New York sheet:
- New York is recorded in this rule set as having adopted the National MUTCD with a state supplement, unconfirmed; this sheet uses national default values. Check whether New York publishes a supplement or its own manual — the state document controls where it differs, and none of it is encoded in this rule set.
This rule set holds no New York-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: New York — MUTCD adoption recorded as: National MUTCD adopted with a state supplement. 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. Rests on a single secondary source and is UNCONFIRMED in this rule set. New York’s supplement is codified in the NYS rules (17 NYCRR), so treat the state text as controlling. This rule set asserts no New York-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
How long is the merging taper for a lane closure in New York?
It depends on posted speed and the width being closed. MUTCD uses L = W·S²/60 below 45 mph and L = W·S at 45 mph and above. The table above computes it for a 12 ft lane at four speeds; the builder recomputes it for your actual lane width.
Do I need an arrow board?
For a stationary lane closure on a multilane road, yes — the arrow board goes at the beginning of the merging taper. It supplements the channelizing devices and the advance signs; it does not replace either.
Does this cover freeway and divided-highway closures?
No, and the tool refuses rather than approximating. TA-30 assumes a non-divided two-way road with four or more through lanes. Divided highways and freeways run off their own plates and need a sheet designed for them.
