Pennsylvania is probably one of the most difficult jurisdictions for managing/operating a system of roads. In addition to the weather-related issues I mentioned above, it's also a state that has a lot of roadway miles in sparsely-populated areas where the level of economic activity simply doesn't support that kind of roadway infrastructure.
I understand you have a similar problem with medical facilities in rural areas, don't you?
Rural eastern Washington is a vast volcanic grassland with a fine network of 2-lane state highways and 3 freeways (I-82, I-90 and US 395). It is also sparsely populated, and the people who live there appreciate that.
But it creates all kinds of problems for services, especially the emergency variety.
