Canadian National Railway (two trestles) and the Kansas City Southern Railroad. The trestles were completed in 1936, after construction of the Spillway.

Many timber trestles were built in the 19th and early 20th centuries with the expectation that they would be temporary. Timber trestles were used to get the railroad to its destination. Once the railroad was running, it was used to transport the material to replace trestles with more permanent

Timber and iron trestles (i.e. bridges) were extensively used in the 19th century, the former making up from 1 to 3 percent of the total length of the average railroad. In the 21st century, steel and sometimes concrete trestles are commonly used to bridge particularly deep valleys, while timber

The steel trestle at
Martinez, California, shown below, is a modern structure with a long expected lifetime compared to a wooden trestle. Being less susceptible to fire damage in this brushy location is also an advantage. The approaches to the

Trestles in cast- or wrought-iron were used during the 19th century on the developing railway network in the United
Kingdom. These generally carried decking consisting of some form of trussed girder, as at
