Inland Waterways Association. A plaque commemorating this was attached to the lock entrance and unveiled by his widow, Sonia Rolt, on 17 January 2009. The now-infilled Weston Branch, which terminated at a wharf at Weston Lullingfields branches off between Frankton Locks and Lockgate Bridge. Only a short section remains, part of which is used for mooring and part as a nature reserve. There is a Canal & River Trust amenity block alongside. Just beyond the junction is bridge 71, a red-brick humped-back road bridge dating from 1785 which remains almost in its original state. It is a grade II listed structure. The canal passes through a peat bog which has been drained since the construction of the canal. This lowering of the water level has meant that during restoration the canal had to be lined to prevent leakage and a new lock was required to lower the water level. This lock was named Graham Palmer Lock after the founder of the Waterway Recovery Group. The Perry Aqueduct crosses the River Perry and was replaced during restoration. The old aqueduct had three small arches and restricted the flow on the river in flood conditions. As it was in a poor state of repair, it was replaced by a single span steel structure. Beyond the aqueduct, the canal is very straight as a diversion was built in 1822. (The original route of the canal had followed a less direct path at the insistence of one of the Proprietors, who wanted the canal to serve his Woodhouse Estate.) Rednal Basin was originally used for transshipment between the canal and the Chester and Shrewsbury Railway. This finished in the 1850s and it subsequently served a bone mill. Although the link to the basin still exists and there is a swing bridge over the entrance, it is not used for boats as it is a nature reserve. At Queen's Head the canal passes under both the old and the new A5 road. There are mooring spaces and some Canal & River Trust buildings at Queen's Head. Following Queen's Head are the three Aston Locks. The top lock has a nature reserve alongside, built during restoration. The canal passes through Maesbury Marsh, a village built largely alongside the canal. Canal Central, an environmentally-friendly building incorporating a post office, shop, tearoom, accommodation and bike and canoe hire was built alongside the canal near the village (just to
