It looped to the south of the railway, and then recrossed it, turning south-west again near station. It was sandwiched between the Dunbridge to Lockerley road and the River Dun, before crossing back to the north side of the tracks at Lockerley. It followed the southern bank of the Dun fairly closely, and the associated earthworks can be readily seen on modern maps almost to East Dean. The railway was built over the canal through East Dean, but two further loops to the south before the canal reached West Dean can be seen. On the edge of West Dean, the canal crossed from Hampshire into Wiltshire. Beyond West Dean, the canal was closer to the railway formation, but still wound from side to side, and diverged further to the north as it passed East Grimstead. On its way, it crossed to the south of the railway and of Dean Road, just before the road and the route of the canal passes under the railway. As it passes East Grimstead, it is marked as "Old Canal" on modern maps. The only extant original bridge is located here. It consists of a single arch built in brick, and it is a grade II listed structure. The railway again ran on top of the canal through West Grimstead, and there was a final loop to the north, before it crossed to the southern side of the railway for the last time.
