EXPOSED
Patching potholes, plowing and salting roads, mowing shoulders, setting cones and flagging traffic, and repairing guardrails and signs are physical work in uncontrolled outdoor environments — almost nothing here is text or screen work an LLM can take. The exposure is not AI writing your job away; it is telematics-driven route optimization, automated plow/spreader control, machine-vision pavement inspection, and autonomous mowing trimming crew sizes and shifting the work toward equipment operation. The CDL and flagger certifications are real credentials but thin legal shields, and the buyer is a DOT budget line, not a client who pays for you personally.
Roughly flat across the period, with year-to-year wobble.
Median pay $40,730 → $50,260 -1.3% in real terms
This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.
So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.
BLS projection, 2024–2034
+3% 159,100 → 163,900 on the projections basis
Growing, and only partly exposed
The BLS expects +3% more of these jobs by 2034, and at 58/100 the work is only partly exposed — some tasks are automatable, the core of the job is not. Nothing here is in tension.
Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.

Holding it up: embodiment . Weakest point: liability shield .
Tasks largely resist digitisation Cutting out a failed pavement edge, tamping hot mix in February rain, chainsawing a downed tree off a two-lane at 3 a.m., and re-tensioning a mangled W-beam guardrail are one-off, site-specific jobs where every hole is a different shape — the 17 rather than 20 reflects that plow routing, salt-rate spreading, and pavement-crack surveys are already being handed to GPS/telematics and camera systems, so parts of the shift are drifting toward monitoring equipment rather than swinging tools.
Hands-on in uncontrolled environments You work inside live traffic on open right-of-way — kneeling in a lane behind a cone taper, riding a mower deck on a 3:1 slope, hanging off the back of a spreader in a whiteout — which is as uncontrolled as a worksite gets, and the 19 instead of 20 only acknowledges that a growing share of hours is spent seated in a cab.
Certification preferred, not legally required A Class B CDL with air-brake and tanker endorsements plus a state flagger card are genuine gate-keepers on who can be dispatched, but neither makes you the person a court names when a work-zone crash happens — the DOT, the resident engineer who signed the traffic control plan, and the contractor's insurer absorb that, which is why this sits at 6 rather than up with licensed trades who stamp their own work.
Meaningful discretion You decide whether a shoulder washout needs closing now or can hold until Monday, how much salt to lay before an ice event, and where to set the taper when a curve limits sight distance — real calls with real consequences, but they run inside the MUTCD Part 6, the state maintenance manual, and a supervisor's dispatch order, which caps this at 9 rather than the engineer-level ambiguity above 14.
The verdict above describes this occupation as a whole. Almost nobody does the typical version of a job — tick what's actually in your week and see how your own mix sits.
Your task mix speaks to task resistance (17/20 here) — how much of the day's work current AI already does. That is the dimension the boxes above are about.
It cannot move the other three. Liability shield (6/20) is whether the law requires a licensed human to sign. Trust premium (7/20) is whether buyers specifically pay for a person. Judgment and accountability (9/20) is whether the role exists to own consequential calls. Those are facts about the occupation's standing, not about which tasks are in your week — a paralegal who does only trial exhibits still holds no licence. Together they are 22 of this occupation's 58 points (38%).
Embodiment (19/20) is also a property of the work rather than the worker, but we don't tag individual tasks as physical or not, so the picker can't tell you anything about it. That's a limit of this tool, not a claim.
Did we get the list right? Tell us what's missing — the tasks are written from the outside, and you're reading this from the inside.
The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 72/100 — SAFE.
Task-mix shift: this occupation genuinely has two tiers. If telematics, machine-vision pavement scanning and autonomous mowing absorb the routine repetitive tier (mowing runs, scheduled salt spreading, inspection logging), the residual job becomes non-repeatable one-off repair — storm damage, guardrail and cable-barrier crash repair, sinkholes, bridge-joint and drainage failures — which is harder to systematize. Score holds high or rises even as headcount falls.
State DOT and MUTCD-derived rules that require a certified Traffic Control Supervisor / ATSSA-certified person to personally sign and be present for temporary traffic control plans in active work zones — several states (e.g. Virginia's TCT/ATCS certification, Michigan's TSA requirement) already mandate a named certified individual on site. Extension of such named-signer requirements to routine maintenance operations, and to sign-off on any autonomous mowing or plow deployment in live traffic, would convert a thin certification into a personal-liability shield.
Winter storm and emergency-response duty formally assigned to named crew leads: the call to close a lane, declare a road impassable, or divert traffic around a washout under incomplete information. Where state DOT operations manuals already vest closure authority in a supervisor on scene rather than a central TMC, that authority is consequential and auditable; broader codification (rather than TMC centralization) raises this.
OSHA or FHWA rulemaking (or state law following work-zone fatality litigation) requiring a human safety officer to authorize the release of an autonomous mower/plow into a public right-of-way, with that person named in the incident record — analogous to the human-attendant requirements in current autonomous shuttle pilots.
The limit. Every lever here protects the role's content, not its headcount. The binding constraint is that the buyer is a state DOT budget line: route optimization and autonomous equipment reduce crew size without ever needing to replace the judgment tier. There is no plausible route to a trust premium — no motorist chooses a pothole crew — so that dimension is omitted.
