Bourne Lock, Bridge And Weir Immediately North Of Bourne Mills

MATERIALS: red brick with ashlar limestone dressings.

DESCRIPTION: the BRIDGE is set across the tail of the lock. Roughly rectangular on plan, its wing walls are gently curved outwards, and are battered, ending in pilasters. The arched opening is segmental, almost semi-circular. The arch has ashlar springers, and there is a plain curved string to the extrados. The parapet is plain, and it and the flank walls have plain stone copings. The LOCK has brick-built walls, which widen to the entrance at the south end. It has large stone copings and ashlar dressings at the gate positions, where there are iron fittings to the gateposts. One original lock-gate partially survives. There are double gate recesses and an arch at the top of the chamber indicates its evolution, showing where the lock was shortened to save water.

SUBSIDIARY FEATURES: the group also includes the adjacent BY-WEIR, which formed part of the site's water management system. This structure is rectangular, and partly stone-built, but was much overgrown at the time of inspection (2009).
