A view of the Pear Tree lane Viaduct that spans the junction of the Dudley Canal Navigations' Dudley No. 1 and No.2 Canals at Parkhead Locks. Here, the bottom lock is full. The building to the right used to be a pumping house. A moored canal boat can also be seen to the right of the upper flight of locks. (Courtesy of Mr. W. R. Lait).
