Two operations, half a mile apart
Fifteen people at the pit and fourteen at the plant
MSHA records 15 employees at Clayton Aggregates and 14 at the Clayton Plant, and the two sit about half a mile apart — 1.50 miles and 0.97 miles from the town centroid. For a small city that is a real aggregate operation on the doorstep rather than a name on a list.
Aggregate is the most road-bound trade there is. Nothing leaves a pit by any route but a truck, so the working life of a vehicle here is short repetitive loaded runs rather than distance.
That road network has no cap to report, and two signs anyway
Those two nodes produce the most easily misread road figures in this lane, so it is worth being precise. Within ten miles the 2025 National Bridge Inventory records 306 structures around one and 303 around the other, and none of them is coded below legal loads — but two are coded posted for load. Both sit in Contra Costa County.
That is not the same as nothing posted. There is no commercial floor to report, because the file records no carrying capacity for those two; a driver still meets a sign at a crossing this measurement has no number for. Our own console tool printed both nodes as a clean zero, which was wrong, and the sidecar behind them was right — we are reporting the sidecar.
The practical version: do not read “no commercial floor” as “no restriction”. On these two it means the opposite of reassuring.
What runs here
A quarry town at the foot of the hills
So whatever you drive, the offer does not change — we buy all of them. Aggregate work puts dump trucks, mixers and aggregate haulers on these roads, flatbeds move the plant and the equipment that serves it, and day cabs run the loads out towards the bay.
Concord, Walnut Creek and Pleasant Hill carry pages of their own and the same trucks work across all of them. Pickups and work trucks are everywhere, and a light truck that has spent its life on quarry approaches has taken more punishment than a suburban one of the same age.
California weight law
The weight table here is not the federal one
That is state law rather than anything local, and it is the rule truck sellers misquote most often. CVC sections 35550 to 35558 set a statutory range of 34,000 to 80,000 lb by axle count and spacing, and § 35551(a) is a table rather than the federal Bridge Formula — no formula is declared in the statute at all.
The California table does not exactly match the Federal Bridge Table, including at three and four axles. So a configuration that is legal under one can be over under the other, and “it makes bridge formula” is a claim about which table you mean. If someone has told you your truck makes it, that is worth knowing before you repeat it.
Questions we actually get
The four that come up every time
Does it have to run? No. But 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. A missing bumper is nothing.
Do I need the title? We need a title, unless the truck is old enough that it never had one. If it is lost, that is a replacement through the DMV and we will walk you through it. If there is a lien on it, say so on the form — that is why the question asks whether the title is in hand rather than whether you own the truck, because those are different situations and they go different ways.
What if it has been in a wreck? Tell us what happened and we will look at it as it is. California sets no percentage: CVC § 544 makes it a judgement about whether repair is economical, so nothing is decided by a formula before we have seen the truck.
How does it get collected, and how am I paid? There is no clock on any of this. We come to you and drive it away, we come to you and tow it, we buy it remotely and arrange the tow, or you drive it to us. Payment is cash or electronic payment.
