Keynsham Hams Bridge (MLN111404)

MATERIALS: pennant stone throughout, squared and coursed on the faces and soffit, ashlar for voussoirs, copings, and quoins.

DESCRIPTION: depressed, four-centred arch with a span of 16ft (5m) and chamfered voussoirs terminating in chamfer stops. Low continuous chamfered plinth around the external faces and the carriageway faces. Arch soffit and carriageway faces in coursed and squared stone. On both external faces the archway is flanked by stepped buttresses, the offsets with drip-mould and arris. Otherwise the faces are plain, continuing unbroken and parallel to the trackbed as straight wing walls, and rising up to form very low parapets without any intermediate moulding. The coping has a shallow fall. Post-war, galvanised steel, round section railings mounted on top of the parapets are not of special interest.
