THE Clyde Tidal Weir is a unique B-listed weir and bridge structure located at Glasgow Green. It has three large steel sluice gates which are raised or lowered depending on the tide and river conditions allowing the Weir to maintain the River Clyde upstream at a constant level. These sluice gates were designed by the engineer and inventor of the “Roller Sluice”, Francis Stoney. In all, 180 sluices were built to his designs and they are located across the world including at the Manchester Ship Canal, the River Rhone at Geneva, the Thames at Richmond. In August 2017, the North gate malfunctioned causing damage to the Tidal Weir. Before it could be lowered back into place, the river level dropped and large parts of banks were exposed. As a consequence, specific areas of the riverbank suffered significant damage. This is still visible at Adelphi Street, Waterside Street and Carstairs Street.
