Why are all the trees dead?
They are still waiting on their permits for water.
Those roads are probably for police and military so they can arrive quickly in case of invasion or citizens becoming uppity.
Also why the US highway system was built, btw. The president who championed it, Eisenhower, was the commander of US allied forces during WW2. While there were other benefits, his goal was to be able to quickly transport troops in the event of a Soviet invasion.
Which is a fucking dumb idea seeing how shitty the US rail system is.

Oops looks like you have to go around the crater, that might add a minute to your journey. If it’s really big, you might have to take a ten minute detour until we can slather some gravel and asphalt over the hole.
