Wrong topic really but... How do you go about repairing a 300 year-old bridge with preservation orders all over it? This one has a ten mile diversion to get from one side to the other, so first thing, they put in a pedestrian footbridge (on the right in the photo). Then they removed most of the infill portion of the arch. Then they designed and fabricated a steel arch, calculated to withstand all the stresses, to support the concrete road surface plus the maximum calculated loading. Then the poured the concrete (as shown), and had to leave it to cure for three weeks. Next stage is tarmac and re-opening - much to the relief of the local publican!! Regards - John

John, it looks like quite an undertaking. What does the bridge look like from below? Does it have arches? The stonework looks ancient. But cutting off access to a pub?? Yikes! The horror!

Hi Gene, Coincidence, but here's a picture of the same bridge taken last summer (not much of a picture - wouldn't have bothered to post it, but it's of interest now). Regards - John

I remember the awe I felt, on a trip to Portugal, being told the bridge I was standing on was built by the Romans. You have 300 year old bridges - how lucky you are. The only bridges we had in Canada 300 years ago were logs that had accidentaly fallen across streams. For some reason none have survived. What a fascinating project it would be, photographing those old bridges.

Bridges, cathedrals, castles, all great opportunities for photographic series projects. In the UK, you folks have lots of them!
