BSC Bridge Structure Type

Definition

Consists of a large number of short spans, supported by splayed vertical elements to provide lateral rigidity.

Description

Traditionally used mainly for railways and constructed from wood timbers. Twentieth century construction has eliminated much of the need for trestles by using more extensive grading and tunneling, however they remain in use as approaches to bridges where required by the local topography.
