The monument comprises the surviving earthworks of the Roman road travelling between the forts at Castell Collen and Caersws. The earthwork of the Roman road is now only visible in parts. The Ty Lettice stretch survives as an earthwork situated within enclosed pasture between SN 9960 6856 in the SE and SN 9944 6880 in the NW. The earthwork is visible as an agger, or raised embankment, measuring c.7m in width and between 0.2m and 0.5m in height. An associated quarry pit is visible immediately to the NE of the central section of this short stretch of road.

The primary Roman road network was designed and constructed by the Roman army for the purpose of military conquest and rule. Roads were built and used throughout Roman Britain from the mid 1st century AD onwards. In Wales, the majority of the Roman road network dates from the Flavian-Trajanic conquest and garrison (between AD 74 and AD 117).

The monument is of national importance for its potential to enhance our knowledge of Roman military organisation. The monument forms an important element within the wider context of the Roman occupation of Wales and the structure itself may be expected to contain archaeological information in regard to chronology and building techniques.

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is linear and measures 320m from NW to SE by 15m transversely.
