Pittsburgh is nothing but on and off ramps and highways going through it.......like a maze of roads and one way streets. A nightmare to navigate!
I’ve never spent any time there, but the 3 rivers restricting travel can’t help.
My husband is from there. We lived there for about 15 years and lived in the suburbs. I would not go downtown because I was intimidated by all those tubes and tunnels and bridges. If you accidentally got onto the wrong one you were so s.o.l. I hated it.
