Old Bridge, White Cart Water, Snuff Mill Road, Glasgow

The Old Bridge over the White Cart Water on Snuff Mill Road in Glasgow is a bridge of uncertain but comparatively early date, likely from the early part of the 18th century, possibly closer to 1700. A datestone from 1624 is believed to relate to an earlier bridge.

The bridge features a large single arch with an approximate span of 20 meters, along with a round-arched subsidiary span on the lower east bank. The main arch springs from the cliffs on the west bank, causing the roadway to slope downwards from west to east.

Constructed mainly of coursed rubble, the bridge includes ashlar voussoirs, and the parapets and some upper masonry have been rebuilt over the years. The pier between the arches is thicker than the main elements of the bridge and is splayed where it widens, resembling pointed cutwaters; however, its ends are squared off rather than pointed or significantly narrowed. The roadway and parapets are narrow, with the coping of the parapets featuring deeply-chamfered arrises.

Additionally, the walls on the west side leading up to Old Castle Road define an early roadway and are themselves of early date.
