This is a batshit stupid idea completely devoid of an ounce of logical thought. The no man's land between highways is dangerous to access, varies immensely in quality, is FREQUENTLY visited by vehicles at high speed during accidents, and would be massively inefficient to run power through. That's to say nothing about the impact of slinging salt all over the entirety of the infrastructure every winter.l which would destroy everything.

Maine has plenty of unused land to solar farm, this is literally one of the worst places to put it.

Find a capped landfill, out of service PFAS infested farmland or literally one of the billions of acres of cheap rural land that's accessible and safe.
