The bridge was constructed from wrought iron and cast iron and was built under the direction of LSWRs chief engineer W.R.Galbraith.
The dual-tracked bridge took three years to build and was opened to rail traffic in 1874.
The viaduct had an axle load limit and as such was limited to certain classes of locomotive.
Regular services were withdrawn in 1968 but the bridge continued to be used for shunting by a local quarry.
In the 1990s the remaining track was removed and the crossing is now used by the Granite Way...a long distance cycle track that runs across Dartmoor.....
The viaduct is one of only two such surviving railway bridges in the UK that uses this type of cast and wrought iron construction.
Below are some images of Meldon Viaduct that I took during our walk....
