Brick-built, a wonderful wide arch. A beautiful piece of scenery, a beautiful piece of engineering. A blend of science and visual poetry. So what happened?
Europe happened. Some small-minded Brussels bureaucrat decided that all bridges carrying anything as major as a three-digit A-road had to be able to carry a certain weight of vehicle. Never mind that there was no demand for the traffic -- never mind that the roads on each side of the road couldn't sustain such vehicles -- Europe demanded that the bridge be replaced, and replaced it was.
Now we have a dull grey concrete rectangle.
There are pictures of the old bridge in the pub. We'll stop and look at them when we pass in the opposite direction.
