Railway bridge over Llanrwst Road, including attached embankment wall to E

The S side of the bridge has coursed red-sandstone piers between a shallow segmental-pointed rusticated arch. The ashlar parapet is castellated above the piers and has a central blank shield. On the N side the abutments are of later rock-faced stone, and the deck is carried on C20 concrete beams. On the SE side is a retaining wall above the River Gyffin, extending approximately 120m between the bridge and the tubular bridge. The wall is in 4 sections and 2 facets. The 1st (W) section is of battered snecked rock-faced stone, incorporating 3 heraldic shields, and a moulded stone cornice to an ashlar parapet. It abuts the square turret at the W end of the 2nd section. The turret is of snecked rock-faced stone with ashlar embattled parapet similar to the bridge. The 2nd section of wall is rubble-stone on a stepped plinth, with moulded cornice to an ashlar parapet, and incorporating 2 more shields. The 2nd section terminates with a higher polygonal turret of snecked rock-faced stone and embattled parapet. The 3rd section is similar to the 2nd section. At the W end of the 4th section is a half-round rock-faced turret with shallow ashlar conical cap. The 4th section is of coursed rock-faced stone and abuts the tubular bridge.
