What makes the routing here awkward is how close the first obstacle sits. Within ten miles the National Bridge Inventory records 175 structures, 9 of them coded below legal loads, and the NEAREST of those is 0.85 miles from the working gate.
Eight of the nine belong to townships
Of those 9 restricted crossings recorded by the National Bridge Inventory, 1 is county-maintained and 7 belong to townships, all of them inside Mifflin County. That is the ordinary Pennsylvania pattern and it is worth spelling out, because it decides who a hauler negotiates with.
The posting power and the bond sit with whichever authority owns the road, so where the townships hold the restrictions the townships are the offices a lane has to satisfy, each of them separately. In this county 7 township-maintained structures fail on load against 1 of the county’s.
The lowest rating among the local group is about fourteen US tons, so these are crossings that take a truck part loaded rather than turning it away. On a short haul that means more trips for the same tonnage.
The nearest big quarry is fifteen miles off
Beyond the quarry, a rail yard sits 8.6 miles away on the North American Rail Network maintained by the Federal Railroad Administration and the Bureau of Transportation Statistics.
For anything larger you leave the county. The Oak Hall Quarry works 14.6 miles off at Boalsburg with 13 people, Con-Stone 14.9 miles away at Aaronsburg with 12, and the Pleasant Gap Aggregate Plant at the same distance with 51 — seven times this quarry’s payroll. The Fulkroad Quarry sits 17.1 miles off in Juniata County.
So the working area is wide and thin, and most of it is in Centre County rather than this one. A truck here spends its day crossing between authorities.
Running part loaded to clear a crossing is normal here, so a truck can show low tonnage and heavy use at once. Between this quarry and the Oak Hall Quarry 14.6 miles off the wear lands on the driveline and the brakes rather than on the odometer.
People call about farms changing hands, retirements and estates, out towards the Oak Hall Quarry 14.6 miles off and the Fulkroad Quarry 17.1 miles away.
