Timber beams survive where lock gates originally hung with some of iron fittings still in place. End sections of embankment slope downwards to curved ends, and southern sections include a large basin for waiting barges to moor in, though much of this basin is now silted up, and it too ends in curved embankments. 2 blocked, semi- circular brick drain openings in west side of lock chamber. The river Lud, running north to south, is culverted and passes under the lock by means of an inverted syphon. Navigation abandoned in 1924.
