Trenance, Cornwall Viaduct |
The original Cornish viaducts / bridges were indeed wooden - built on masonary piers.
I found the photo below (in the public domain) of the Truro Railway Carvedras Viaduct from 1859. This shows the wooden construction supporting the railway lines. At the time this was done to save money, but was a false economy as stronger stone viaducts had to be built in 1899.
The original stone piers remain next to the newer viaducts.

Those wooden supports look quite fragile compared to today's bridge structures. Very interesting design. The viaducts are really impressive looking with a very pleasant place to sit and watch the one in Truro! Great posts, Mike.
ReplyDeleteThanks Ann. It is said that the Victorian railway engineer Isambard Kingdom Brunel was responsible for the wooden design - he certainly got that wrong! They look very precarious.
ReplyDeleteThe park in Truro is very pleasant and has a bandstand for the summer nights.
