Packhorse bridge
（重定向自Packhorse bridges）
A packhorse bridge is a bridge intended to carry packhorses (horses loaded with sidebags or panniers) across a river or stream. Typically a packhorse bridge consists of one or more narrow (one horse wide) masonry arches, and has low parapets so as not to interfere with the horse's panniers. Multi-arched examples sometimes have triangular cutwaters that are extended upwards to form pedestrian refuges.
