The Old Bridge

The Old Bridge is a Grade II* listed road bridge that has been converted for pedestrian use. It features four low segmental arches with cutwaters and a parapet. The original section, built in 1726, has rough stone arches with well-recessed stone voussoirs and rubble stone above. There are three large cutwaters made of squared stone, each topped with pyramidal forms that reach up to the parapet coping.

On the central cutwater, there is a plinth with panelled sides, a thin cornice, and a curved top adorned with a ball finial. This plinth bears an inscription stating, "This bridge was erected at the sole expense of Sir John Philipps of Picton Castle Bart Anno 1726 Michael Prust Esq Mayor in memory whereof this was set up by the mayor and council." There is also a second inscription noting repairs made in 1829 during the reign of King George IV, who crossed the bridge on his return from Ireland on September 13, 1821. A third inscription indicates that the bridge was widened and repaired in 1848 under the direction of the Magistrates of the County of the town of Haverfordwest at the expense of the County.

The downstream side, constructed in 1848, features grey limestone segmental arches with cut stone voussoirs that spring from the cutwaters, which also have pyramidal tops and short piers leading up to a raised band. The band steps down over the right arch, and the bridge is finished with tooled grey stone copings. The bridge measures approximately 38 yards (34.75 metres) long and 23 feet (7 metres) wide.
