Now a minor road that links the A40 with Mathry and the road to St David's, this was formerly a raised causeway, possibly of Neolithic date, across the boggy valley of the upper Cleddau. As explained by Damien Walford Davies and Anne Eastham in their book 'Saints and Stones', Gomer, 2002, "The causeway is constructed of huge Preseli boulders, interlocking with each other and rising and falling with the water levels in the marsh or lake bed beneath....In 4000 years or so of use, smaller stones and layers of water macadam have been added by generations of road menders to build up the carriageway,until in the 19th century culm and rubble with fragments of pottery became incorporated in the fill and parapets were added" to the bridge.
