I don't actually know much about the Elmira area, but I do have this bit
of area roadgeek trivia.
The east end of E. Water St (NY 352) is at a standard bridge over I-86/NY
17, with ramps to the highway (Exit 56, sort of a diamond, fused with the
next interchange north). Nothing particularly unusual about it.
However, before the I-86 rebuild there was a different bridge at that
location. What was unusual about it?
