Viaduct.

The sun was setting as I went under the Cannington viaduct (just outside Lyme Regis ) tonight so I stopped to see if I could get a blip.
The viaduct was for trains travelling from Axminster to Lyme back in the day. It was built of concrete ,with one Arch reinforced with an inner brick arch later.(just visible)
A shame it has been disused for so long.
