The National Monuments Service's description

Spanning the River Nore with nearby castle (LA016-017001-) 150m to the SE and mill site (LA016-017002-) immediately to the N. This six-arch limestone bridge (road Wth 18m) with rubble limestone cutwaters, is a multi-period structure the earlier bridge is located on the upstream or W side. The arch rings (Wth 4.65m N-S; H 3.4m) on the upriver side consist of undressed roughly cut voussoirs while those on the downriver side consist of cut stone dressed wedge shaped voussoirs. On the underside of the bridge a straight joint is clearly visible where the bridge was widened by 9.1m in the 18th century. The earlier bridge measured 5.6m E-W wide on the underside of the arch, if this bridge had a parapet wall on either side thie original road over the bridge may have measured approx. 4m. The downstream or E face was added to the bridge in the 18th century possibly when the nearby Nore Flour Mills were constructed during this period (c. 1750) The earlier bridge appears to have been contemporary with the medieval castle that is located on the ridge looking down over the crossing point of the River Nore.
