The span of bridge columns is widened to 12–30m, longer than that used for conventional bridges, in order to reduce the number of bridge columns used, the construction period and cost.

In terms of construction period and cost, the lower part (bridge columns) of a bridge typically takes longer and is more costly to build than the upper part (bridge girders). To reduce the construction period and cost, this mode of construction uses a reduced number of bridge columns by increasing the span (bridge length) between them. Parts are jointed and fixed by inserting pins rather than by using nuts and bolts. These features are not seen in conventional bridges.

Specifications:
Span: 12 to 30 m
Bridge length is adjusted by changing intermediate members.
