Can't just rely on wheel-brakes, though. That why transmissions downshift, and why some heavy trucks have a compression-induced "Jake" Brake.
14% grades are not uncommon in the East, either, in the Appalachians, as in PA Route 1006 down the west side of Tuscarora Mountain....the Old U.S. 30 Lincoln Highway before 30 was rerouted.
......Ever drive that one, tex 2670, since you're from PA?
I haven't, but maybe someday if I ever can bring myself to make the long trip and bring my bike to go thru the abandoned Penna Turnpike Tunnels at Ray's Hill and Sideling Hill, I'll take a detour and drive that route too.
^ regarding braking, my truck has an exhaust brake (6.7 diesel) and it is very useful in situations like this hill. In tow haul mode the transmission will shift to second on this hill and engine will run at 2500-3000 rpms and really hold the truck back well. I would never want to tow again (140000 + combined weight) without an exhaust brake and tow/haul mode. My truck is a 2012, apparently the newer ones have a better exhaust brake.
Highway 140 would be a worthy champ for "loneliest road" for sure; it does not wear the crown because practically no one ever drives it or even knows about it, it is frequently closed (or parts of it anyway) in winter, no services or cell phone coverage at all. You are on your own if you break down, flag down a passing car is your only hope.
