The weatherboarded top was originally supported by the timber trestle, which has since been enclosed within a brick roundhouse.

Once, no doubt, a timber trestle had provided access to the mine, but it had rotted away long ago.

It was a 732-metre long low timber trestle.

A temporary timber trestle was constructed while a new bridge was planned at the western edge of the town of Hancock.

There were no fans supporting the track, instead timber trusses were built directly on top of the timber trestles.

The timber trestles of the former Camas Prairie Railroad are visible throughout the area.

Many timber trestles were built in the 19th and early 20th centuries with the expectation that they would be temporary.

Thus, few timber trestles survived into the 20th century.

Most of the bridges were originally timber trestles but all were subsequently rebuilt in steel using suitable scrap material from the factory.

The planned embankment had been replaced by timber trestle which was damaged by winds during construction.
