| location: |
A large, 5" gauge "representational" model of a section of Isambard Kingdom Brunel's original wooden Walkham Viaduct, bridging the Walkham Valley, nr. Grenofel, Devon.
The wooden bridge model was specially built for the Museum, to fit against one of the walls of Arch Three, straddling the entrance to Arch Four.
The original bridge
The original viaduct was constructed in 1859 for the South Devon Railway, from sixteen spans of Baltic Pine bridgework seated on masonry pillars, and its design was reckoned to represent the best of Brunel's series of wooden viaducts. It was finally replaced in 1910 with a steel version (using the same pillars), and this in turn was demolished in the 1965. A replacement, the Gem Bridge, is due to open in 2012.
