Leith, Dock Place, Winches And Capstans, Swing Bridge And Lock Gates Including Turning Platforms

Early to mid-19th century swing bridge following the circa 1800-1806 template devised by John Rennie/Ralph Walker. Alterations by James Leslie, circa 1846-50. Rare, Rennie/Walker-type cast iron swing bridge (with associated lock gates, turning platforms, winches and capstans) spanning the Old East and West Dock entrance between Dock Place and Rennie's Isle, Leith.

BRIDGE AND TURNING PLATFORMS: shallow-arch, three-pin, braced cast iron swing bridge with six ribs. 27 metre long with 10 metre clear span over water. 4.7 metre width. Timber-planked deck with wrought iron handrails along outer sides. Ashlar, turning circle platforms supporting bridge structure to north and south of former dock entrance cut. Recessed ashlar walls with stone access steps.

LOCK GATES: remains of timber lock gates set flush with the quayside on either side of the entrance lock. Timber with some metal sheathing. Timber-decked walkways and wrought iron handrails matching those on the swing bridge.

WINCHES AND CAPSTANS: seven cast iron hand winches that operated the lock gates (originally two flanking each gate). Larger hand winch located on south turning platform operated the swing bridge. Two ashlar-mounted, cast iron capstans, one on either platform.
