Inchnacardoch Trestle Bridge

The Inchnacardoch Trestle Bridge was constructed to carry the Biggest Little Railway across a stream in Inchnacardoch Forest. Dick Strawbridge nicknamed the location Inchnacardoch Canyon due to the scale height and length of the bridge.

Real World Equivalent
A trestle bridge is composed of a number of short spans supported by rigid frames. The bridges were extensively used in railway construction during the 19th and early 20th century.

The world's largest wooden trestle bridge is the Goat Canyon Trestle in San Diago, California. The bridge was constructed in 1933 as part of the San Diego and Arizona Eastern Railway. The line is currently closed to rail traffic and the bridge is now a popular destination for hikers. Although a common feature of early railways in the United Kingdom, most wooden trestle bridges were eventually replaced by viaducts. Two surviving examples can be found on the Aberystwith and Welsh Coast Railway, crossing the River Mawddach at Barmouth and Penmaenpool.
