Full Description

Thomas Telford-designed "stagecoach" bridge which has a series of sluice gates to prevent seawater getting upstream into the Mound aldergrove swamps. This area included land reclaimed by a 1,000 yd embankment, which became known as The Mound, constructed by Sutherland Estates in 1816 to carry the new Parlimentary road over Loch Fleet.

The pent up waters of Loch Fleet are drained by an impressive series of sluice gates (four in 1816, increased to six in 1837 by Joseph Mitchell) in the six-span bridge. Each arch is fitted with a wooden non-returnable flap valve which prevents sea water from flowing up-river while allowing fresh water to drain away. A system of chains and pulleys operate the sluices, the winding gear housed in small stone huts each side of the bridge <1>.

Stone built bridge with 12 sluice gates, two below each arch of bridge. The arches have a timber panel cover each on east side of Telford’s bridge. A series of metal winches extend out from the bridge above each sluice gate. Two winch buildings at either side of bridge consist of small single storey buildings with a slanted corrugated iron roof. <2>

Several pictures of the Mound sluice gates and components are pictured on the Dornoch Historylinks Image Library (seach Nos. 10363-10367 at the link below). The winch for operating the sluice gates was repositioned outside the Historylinks Museum in 2004. <3>
