At some point face-to-face iron ties were added to hold the bridge together.
The bridge is built over a weir between two ponds (part of the Bosherston Lily Ponds). There are eight segmental arches in limestone, one with slightly projecting keystones. The arch rings are in ashlars; the rest of the arches in common stonework. There are a low rebuilt parapet walls, with slight wing walls at each end, on either side of the 3.3-metre (11 ft) roadway.
