2016-08-26 (Day 239) Polmont Bridge

This fine, if rather overgrown, bridge is in Polmont. But it does take a bit of finding.

I'm guessing it was a railay bridge, now massively over-specified as a little-used footbridge. I wonder if it is even maintained, or is it something that the world has forgotten about, and it will remain ignored until one day it falls down?
