Williamson County
A quarry that ran out of room and went underground
Vulcan Materials works a 35-person operation here, approved for state highway work and matched to the register at 0.02 miles — and the mine regulator codes it Underground.
That is not a common thing to find inside a metropolitan ring, and there is a reason for it beyond the geology. Underground working is capital a small operator does not commit. A quarry inside a growing metropolitan area also runs out of room and runs into its neighbours, and going under ground it already owns is how it keeps producing where the market is.
A second row here is a different animal entirely: the Globe Quarry, six people, run by a county highway department rather than a company. Two of the state’s eight county-run quarries are in this one batch of ten.
Two fleets in one town, and they wore out differently
Those two facts combine into something useful for a seller. A room-and-pillar mine runs at stable temperature and out of the weather, so a machine that stayed inside the Vulcan Materials workings had a materially different life from the road fleet hauling into the metropolitan market above it. At 35 people both fleets certainly existed.
The Globe Quarry side of Williamson County is different again. A public fleet is bought on a procurement cycle to a written specification, maintained by a county garage that keeps its own records, kept far longer than a commercial operator would keep it, and does snow, brush and flood work as well as hauling stone.
So the hours run low against the age and the duty is varied, and the paperwork behind the machine is a public record rather than a private one. Three quite different histories, one town, and nothing in a node name separates them.
The road network
The ring around the city rebuilt its bridges
All three fleets run over a network that restricts almost none of itself. Williamson County posts 6 of its 211 county-maintained bridges — 2.8 per cent, 85th of the 92 Tennessee counties with a real stock.
That is the whole ring, not a local quirk: Robertson posts 1.7 per cent, Trousdale 1.6, Dickson 3.0 and Sumner 4.5, against a statewide county rate of 12.9. A growing metropolitan ring rebuilds its roads, and a rebuilt bridge is not a posted one.
Within 10 miles of the Vulcan Materials workings the inventory records 303 structures, 17 of them posted and only 3 county-maintained, the nearest 1.9 miles out. All seventeen clear 11.0 metric tonnes and the binding cap is 12.6.
So what limits a load here is the weight law and the traffic rather than the crossings, and a machine off this ring ran full on open roads: engine hours and mileage rather than part loads and running-gear wear.

Tennessee weight law
Which leaves the code doing the rationing
So on these roads the numbers in the statute are the binding constraint rather than a backstop.
Tenn. Code Ann. § 55-7-203 sets 80,000 lb gross, 20,000 lb on a single axle and 34,000 lb on a tandem, with up to 550 lb more for emissions-reduction equipment. Subsection (b)(7) grants a ten per cent margin of error on the weighing to logging, sand, coal, clay, shale, phosphate, solid waste, recovered materials, farm trucks and machinery trucks — off the interstate system only. Crushed stone is absent, and so are limestone, aggregate and gravel.
Tenn. Code § 47-26-812 adds an axle-citation shield and five hundred pounds for a natural resources load, from a weights-and-measures chapter about certified public weighers rather than the motor vehicle code. Off the interstate again.
And § 55-7-104 is the one that costs a working day: an overweight vehicle may not be moved until the load is reduced into compliance or a permit obtained, and failing to comply is itself a Class C misdemeanour.
Tenn. Code Ann. § 55-7-203 and § 55-7-104, and Tenn. Code § 47-26-812, as summarised by the University of Tennessee County Technical Assistance Service. Information, not legal advice.
Tennessee paperwork
We need a title — unless it never had one
Then the paperwork, which is that sentence and a short list of fixes.
Everything after that sentence is a fix rather than a category. A lost title has a counter replacement. Where none exists there is a bonded route. Neither one stops a sale.
The salvage rule is the one people repeat wrongly. Tennessee’s salvage and rebuilt part is built on the term passenger motor vehicle, and § 55-3-201 defines that as a vehicle ten model years old or less which, if it is a light-duty truck or a multipurpose vehicle, is rated at not more than nine thousand pounds gross.
So the seventy-five per cent threshold does not reach a truck rated above nine thousand pounds at any age, and does not reach a vehicle of any kind over ten model years old. Those limbs describe the class the part governs rather than exceptions inside it. Whether some other provision reaches such a vehicle was not determined and is not claimed here.
Tenn. Code Ann. § 55-3-201 and § 55-3-211, with the Tennessee Department of Revenue’s guidance. Information, not legal advice, and only as current as the day those were read.
What we buy here
All of that iron is iron we buy. Underground haulers and loader support off the Vulcan Materials workings. Tandem dumps and mixers off the road fleet feeding a market that keeps building. County plant off the Globe Quarry end — snow gear and brush trucks as well as dumps.
Day cabs, road tractors, box trucks, straight trucks, flatbeds, rollbacks, tankers, service bodies, work trucks and pickups too — not a Williamson County thing in particular, they run everywhere.
Whatever you drive, the offer doesn’t change. We buy all of them.
We buy complete trucks. If the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Small things — a missing bumper — are fine.
Straight answers
The questions we get asked in Franklin
- Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Rust is not a disqualifier.
- The engine is out of it. Is that different?Yes, and that is the line. A tired engine is fine; an engine that has been pulled and sold means we can’t buy the truck.
- What about the title?We need one unless the truck is old enough that it never had one. Lost titles have a counter replacement, and where none exists there is a bonded route.
- It worked underground and never saw a road.Then say so. Inside the Vulcan Materials workings there is no weather, no salt and no freeze-thaw, and it usually shows in the hydraulics and the paint.
- Low hours, twenty years old, ex-county.That is what a Williamson County public fleet produces, and it is not a warning. Public maintenance records usually exist, which helps.
- How do you pay?Cash or electronic payment, whichever suits you.
Why people call
Beyond a machine that has simply done its cycles, the reasons here are ordinary ones. Retiring. A medical that went the wrong way. A county surplusing a truck it kept far longer than a company would have.
The yards around the Vulcan Materials pit and out across Williamson County usually have one standing that finished its last job and never got another.
Most of those aren’t happy reasons, and we don’t treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That’s what we’re here for.
