Crossings of the Tees

This adventure/project began as a result of a short story competition - Crossing the Tees - to which I was introduced through Prompted-2-Write. I decided on the spur of the moment to visit, photograph and traverse (where possible) all the crossings of the Tees.
Several trawls of Ordnance Survey maps and close scrutiny by Google maps gave me an initial list of fifty-two crossings, more than double what I had guessed! I knew that I had included some barrages and weirs. Did they count as crossings? Railway bridges certainly did, even the three that no longer carried rail tracks. Some I suspected, but could not tell from the maps, were probably constructed to carry water or perhaps sewage pipes. I decided that I would simply check them out as I journeyed downstream.
