Mm58 Exits & Entrances

The sun forgot to come out from behind the clouds today. That's ok as I had resolved to respond to the Mono Monday challenge and sunrises & sunsets do not lend themselves so well to being presented in mono!
So here is my offering - the entrance to a footbridge which, in turn, gives access to a park. I'm told that the arches in the background are all that remain of a former railway line. Paying close attention to the 'leading lines' mentioned by hobbs in his blip earlier today!

The colour version and three other attempts are in my Exits & Entrances album.
