Variant Definition
Arch (multiple)

A bridge or culvert, the span of which consists of multiple (i.e. two or more) arches.

Arch (single)

A bridge or culvert, the span of which consists of a single arch.

Beam / girder / slab

A bridge or culvert, the span of which consists of 'beams' or 'girders' (including flat stone slabs): may be single or multiple span; includes bridges with plate-girder sides, but excludes those with lattice-girder sides.

Cantelever

A bridge, the main span of which consists is a cantilevered structure.

Combination

A bridge or culvert, with more than one variant of span. The variation may be across the width of the structure (which is usually the result of bridge-widening) or it may be along its length (e.g. arches either side of a beam or girder central span).

Lattice-girder

A bridge, the span of which consists of a beam or girder deck with lattice-girder sides.

Pipe

A bridge or culvert, the span of which consists of consists solely or primarily of a single pipe, or multiple pipes that form a single structure.

Pre-cast segmental
