A lot of our residential infrastructure is underground, because of the weather we have. Though, there's a fair amount of aerial hardware as well. Where I live is famous for ice storms, and every few years there's a major outage that lasts anywhere from 12 to 48 hours. They're rare, but they do occur. More often it's because someone hit a pole or ground mount transformer, versus a falling branch or lightning bolt.

I still prefer ice, snow, and occasional outages to unbearable heat and humidity, earthquake, and hurricane tradeoff being further south or west.

To answer OP, there's a visible change in road surface and signage not only at state borders, but even between county and town lines. Each county handles the road a different way, and the finish/quality can differ a LOT even between municipalities and counties.
