Just outside Keswick, the old railway line and the River Greta go under the A66, carried by this bridge which, in September 1999, was voted the Best Concrete Engineering Structure of the Century.
I can only assume that it won the award for its engineering qualities because, apart from a rather pleasing curve, it has very little going for it aesthetically.
Much more pleasing to the eye was this wooden walkway which we followed around a series of bends, tracking the course of the river and gradually twisting away from the noise of the traffic speeding overhead.
We were, however, a little puzzled about the absence of the railway line. Surely the train could not have negotiated bends like these. It would be akin to riding the Wild Mouse at Blackpool Pleasure Beach.
I think it would be safe to describe this tunnel as being disused!
