This is the Ed Labrador Memorial Bridge.
It is actually on PoCo property but I let them use it so nobody has ever complained.
The area up there is a Gopher Tortoise preserve and vehicles are discouraged. The bridge saves them a mile walk it they have to look at anything. The poles are 100 feet high so any serious maintenance gets done by helicopter. It is a 230kv line.
