Just found this place and decided to stop in and say, "hi!"
I've always had an interest in the unused/dilapidated sections of interstate that pockmark our country as well as tunnels. Traveled the PA Turnpike and I-80 a ton growing up. It was always a game to try to spy the old tunnels that are no longer in us there.
Here in FL we don't have many (any) tunnels, but given the urban sprawl there is always some interesting road construction/urban planning going on.
