The PA Turnpike is ripe for this kind of chaos. For one thing, it runs through higher elevations in the Allegheny Mountains where it snows a lot. To make matter worse, much of the highway was built on a former railroad right-of-way so it is very narrow. I think the longest distance between interchanges is 36 miles, and when you drive along that stretch you have a concrete barrier on your left and lots of hills and ridges on your right.

Every road in PA that runs East-West more than about 100 miles will run through the higher elevations; the ridges are endless, and most of the time we don't shut down roads for any reason.

NOAA/NWS screwed these people over. You're right about the PA turnpike, but this has nothing to do with narrow roads or bad grades.

I wonder how many took the alternate Route US 30.

Up and down the mountains.
