Limestone country, and its quarries
This is limestone country.
Curtin Gap Quarry works broken limestone with eighteen people about 2 miles east. Pleasant Gap Aggregate Plant #2 has fifty-one. Oak Hall Quarry, thirteen people, sits about 9 miles south, and the North American Rail Network maintained by the Federal Railroad Administration and the Bureau of Transportation Statistics lists the Sunnyside yard about a mile west of the middle of town.
The shortest hauls are the hardest ones
Those distances are the whole story for a truck here. A run of two or three miles, repeated all day, is the most punishing work a dump truck does — loaded, braked, tipped, turned round and loaded again, with no stretch of road long enough to let anything cool down.
So brakes, clutches and suspensions here go long before the engine does, and the odometer barely moves while it happens. A Bellefonte tri-axle with 180,000 miles on it has usually had a harder life than the number suggests.
A Curtin Gap truck and a Pleasant Gap truck can do the same work all week and come apart in different places.
Posted roads, and who does the posting
It is on exactly those short lanes that posting decides the cost. PennDOT posts limits on state-designated highways and local authorities post the rest, on the structural condition of the road, so the number that binds a loaded truck between a pit and a lime plant is usually a local one.
The same rule sets who pays when the road gives out. A permittee has to accept financial responsibility for maintenance beyond normal wear caused by over-posted-weight vehicles, and post security against it. In Pennsylvania the cost of the road wearing out lands on the carrier — which is the opposite of how several neighbouring states handle it.
Curtin Gap Quarry and Oak Hall Quarry both feed lanes like that, and Centre County townships own most of what they cross.
Dump trucks and aggregate haulers first, because that is what the valley runs. Day cabs and road tractors for the outbound lime. Box trucks, flatbeds, service bodies, and the pickups and work trucks that follow the crews around.
Most of it works between Curtin Gap Quarry, Oak Hall Quarry and the Pleasant Gap plants.
A back that won’t take another season of it.
Yards around Pleasant Gap and out toward Clinton County usually have one sitting.
