I’ve written about the Byker Viaduct before, including as recently as July, but I’ve just found this brilliant video about its construction:

I’ve long understood that it was notable for the sections being glued together, but I couldn’t quite visualise what that meant: it turns out it simply means spreading glue, by hand, on the two surfaces and spreading them together. Remarkable!

I also didn’t know that the arches in the supports were designed to allow sections of the viaduct to pass under them as part of the construction process, which is a very neat solution.
