A roughly 720m stretch of discontinuous linear earthworks, thought to represent the agger of segment of the Roman road west of Carmarthen (Nprn114111), running ESE-WNW from SN15631823 to SN14921838.
Section to the east = Nprn400972.
Section to the west = Nprn400973.

A section taken across this section of earthworks (at SN15151834?), in 1993, showed that the agger, or raised causeway, hade up of shale chippings, had been constructed on a foundation of large boulders over natural peat, with a cobbled roadway, showing possible wheel-ruts, established on top.
