The Crowhurst 17 arch viaduct construction was overseen my Great Grandfather, Harold Marriott, who lived in Sidley at that time and had a building firm with the Harman family. The viaduct was constructed using bricks, so I am told, from the Turkey Road brickworks (where my Great Grandfather, on my Nan's side of the family, worked). The demolition was overseen by my Grandfather, Joseph Marriott.
As I felt that my family deserved it, before the link road construction was started, I went down to the site of the demolished viaduct and managed to dig up a single engineering brick, which I have kept for posterity!
Such a shame. In other parts of the UK these viaducts, although no longer used by the railway network (due to bl**dy Beeching), were recognised for their engineering and beauty.
So glad to have stumbled on your photos. I was actually looking for the history of the Bridgend property at the end of Glovers Lane in Sidley and got sidetracked!
