Union County
Three quarries, and only one of them sells to the state
Three quarries are filed under Maynardville and the state register separates them sharply. Vulcan Materials works the Maynardville Quarry with seven people and is approved for highway work, matched at 0.27 miles. The Loyston Road Quarry carries six and Tri County Stone carries six, and neither is on that list.
Absence from the register is not evidence anything has closed — it only publishes what is currently approved. What it does establish is where the stone goes: private, county, industrial or out-of-state customers rather than state highway projects. Which in practice means irregular utilisation and commercial paperwork rather than the regulatory kind.
That is a real split inside one small town. Two thirds of the operations here are working to a customer’s requirements rather than to a state specification, and the equipment histories follow from that.
The road network
A restricted county, and the caps sit in an awkward place
Those three share a county network that posts more than most. Union County posts 7 of its 43 county-maintained bridges — 16.3 per cent, well above the statewide county rate of 12.9.
Within ten miles of the Loyston Road Quarry there are 14 posted structures and 8 of them are county-maintained, the nearest 1.7 miles out. The lowest raw rating is 2.9 metric tonnes, which is far below an empty tandem dump and so not a crossing anything commercial uses.
The cap that binds a loaded truck is 15.6 tonnes at the Loyston Road and Maynardville pits and 18.5 at Tri County Stone. Against the eleven tonnes an empty tandem already weighs, 15.6 admits about four and a half tonnes of stone — a part load, not a full one, on any route with that crossing on it.
FHWA National Bridge Inventory 2025, Tennessee file, items 21, 41, 64 and 70. Operating rating is the gross weight of the rating vehicle, so a cap admits roughly itself less an empty tandem’s tare.
Ridge and Valley
The map lies about how far things are
Those distances are also less useful here than they look, because of the shape of the ground. Union County sits in the Ridge and Valley province, where folded and faulted Palaeozoic rock has weathered into long parallel ridges and valleys running north-east to south-west.
The roads follow that grain. Along a valley a route is straight and quick; across one it climbs and descends a ridge every few miles. So haul distance understates the cost of a job in the cross-grain direction and overstates it along the valley, and a service area that looks like a circle is in practice long and narrow.
The valleys also hold the limestone and dolomite this trade quarries, which is why the pits themselves line up in the same direction as the roads. One geometry, doing both jobs.
Tennessee weight law
Eleven trades get a margin. Stone is not among them
All three pits work under the same ceiling and none of them gets the one concession that would help.
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 rather than the motor vehicle code. Off the interstate as well.
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. On a county network posting 16.3 per cent of itself, that rule and the route book are the same subject.

Tennessee paperwork
We need a title — unless it never had one
Then the paperwork, which is that sentence plus two fixes.
A lost title has a counter replacement. Where none exists there is a bonded route. Neither is unusual and neither stops a sale.
The salvage rule is the one that gets repeated 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, when 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 asserted 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. Tandem dumps and aggregate haulers off the Vulcan Materials pit and the Loyston Road Quarry. Smaller plant off Tri County Stone, where six people run the whole operation.
Day cabs, road tractors, box trucks, straight trucks, flatbeds, rollbacks, tankers, service bodies, work trucks and pickups as well — not a Union 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 Maynardville
- 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 a pit that is not on the state list. Is that a problem?No. Two of the three around Union County are not, and it says where the stone went rather than anything about the truck.
- It has run part loaded for years on Loyston Road.Then the driveline has probably had an easier life than the odometer suggests, and the hoist and body a harder one. Tell us about those.
- How do you pay?Cash or electronic payment, whichever suits you.
Why people call
Beyond a truck that has simply done its seasons, the reasons in a small county are the small ones. Retiring. A medical that went the wrong way. A six-man operation going down to one machine when a customer stopped ordering.
The yards along Loyston Road and out past Tri County Stone usually have one standing that has not moved since the last load went out.
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.
