 The initial plans only made provision for a lock which was long, even though all the other locks on the canal were long, but reworking created space for a standard length lock.Tuel Lane Lock was built to the west of the original locks 3 and 4, replacing both, and a tunnel was built under the A58 road junction.The first boat to use the lock and make the passage between the restored Rochdale Canal and the Calder and Hebble Navigation did so on 11 April 1996, and the official opening took place on 3 May.
