Go Under Atlantic Avenue

If you haven't heard, and if what's under your feet is your kind of thing, then you should know that tours of the old subway tunnel under Atlantic Avenue are being held again. What's it like down there? Check out Nathan Kensinger Photography for a look. He's posted several pics from a recent trip down there. He writes:This tunnel was built in 1844 and sealed in the 1860's. It was considered lost until Brooklyn's Bob Diamond discovered an entrance in 1980. The tunnel runs underneath Atlantic Avenue in Brooklyn. Entry is gained through a manhole cover in the middle of a busy intersection. The tunnel was closed to the public for the last five years, but it will now be open at specific times.Check out more information about the tunnel and tours here.
