I was asked about some issues with Rutters bridge and took the opportunity of a visit to friends to inspect and record it. Here is a detailed report associated with a 3D model you can download and inspect for yourself. It is long but I think worthwhile. I am posting just a short summary with a link to a pdf which looks rather different from usual.
The bridge at Kinclaven is relatively late for a "masonry" arch (1903-5) but has a lot of interesting things to tell us. The main visible parts are stone but the voussoirs are precast concrete and the bulk of the arch mass insitu concrete.
It is always fascinating to see how other people do things. This railway viaduct in Aachen Has had a great deal of work done on it by the Bahn.
A flying visit to a joke bridge to finish the year.
The bridge at Regensburg is old and long. It was good to get back there. There is a lot to be drawn from it and more yet to see if I ever get back.
A visit to Nuremberg (otherwise Nuernberg) to examine the Fleischbruecke extended into a walk around of series of bridges old and new.
I heard about the Kraemerbruecke some years ago. A lovely stone bridge with shops over just like the old London Bridge. Managed a visit in August and it has taken till Christmas to get it written up for here.
A stone arch, highly skewed and cut on the “French” pattern.
South bridge is just one span of a viaduct which is only exposed where it crosses the Cowgate. There is a central arch which is presumably original, with a matching strip on one side and a rather different section added at the other. Lots of cracks and movement to explore.
I had no idea there were two Alcantaras. al-QanTarah (القنطرة) means "the bridge", says Wikipedia, which explains that. Many more then I guess but these both cross the Tagus. The other is more famous, possibly for good reason but this was well worth a visit.
I find Edinburgh endlessly fascinating. When I lived in Dundee it was a place for an excursion. From Exeter it is a rather harder journey, but I was there for a Future of Design Conference in April and took the chance to look again at the bridges over Cowgate, south of the old High Street. I did some work on South Bridge back in the early 90s and that will (probably) feature next month. It has 17 spans. How many spans there really are in George IV Bridge I don’t know but it is, in any case, a very different bridge.
I have been wanting to get some decent pictures of William Edward’s bridge in Pontipridd for some time (years). March provided an opportunity but it was cold and wet and the pictures weren’t that good so try again. What I did find, though, was this amazing effort from IKB. Can it be chance that it is the same span?
This month we look at a small private bridge across the Tamar in North Devon and Cornwall.
The railway viaduct at Castle Garth in Newcastle was constructed on centres built with 12 inch boards. The gaps between boards would have coincided with joints between brick courses, allowing the mortar to fall out. A possible explanation for ring separation in brick arches?
A scheduled monument dated to the second quarter of the 18th Century, this badly deformed bridge crosses Afon Mawddach on the southern exit from Llanelltyd. Formerly carrying the A470, it has been bypassed by a modern bridge which will surely be gone long before this one.
