Bridges, I have a fascination for them. I like the metaphors they generate, the idea of two sides meeting in a sort of 'set in stone' harmony.  Harmony ( The term harmony derives from the Greek ἁρμονία (harmonía), meaning "joint, agreement, concord") (Pinched from Wikipedia), seems to have many facets, and is very subjective. Concorde from the outside was not very harmonic, unless the sound of four RR Olympus 593s in full reheat, floats your boat. Anyway, back to the lack of thread. Time. Yup, that common or garden commodity that everyone can use, or fritter away, to their heart's content. In good old Blighty, we have set our clocks to Zulu, or GMT, if you prefer, or even UTC. I for one would like to see the damned clocks left alone form now on. If you don't like it, get up earlier, or later, whatever. Not much in the way of bridge building, but it does mean that Midday is actually Midday! The sun is at it's local highest point. Above the thick cloud cover. So I suppose really it doesn't matter.
There are at least 3 bridges in the photo. One a road over water, one a Railway over the road. The last one a disused railway over a disused road. Well, both are now tracks and footpaths.
