It's called the Worcester Viaduct. (Who would have guessed?) 68 arches. It looks a magnificent piece of engineering but I read in the online version of the Worcester News that it initially failed government inspections. The WN article ends thus:
"And on an engineering footnote, the arch which takes the railway viaduct over Croft Road was the first in the country to be built 'on the skew.' It's worth looking at it the next time you pass under, a construction marvel in brickwork erected at a marked angle."
I'd want to have a look if I was there.
