At Kimbridge Junction, the Southampton & Salisbury Canal left the Andover Canal passing under a bridge carrying the towing path of the latter NG Ref: SU332262. WGS84: 51° 02′ 05″ N, 1° 31′ 36″ W.. Immediately, the Salisbury Arm negotiated a stop lock to prevent the Andover from losing water should there be any leaks in the Salisbury Arm beyond. Although signs of the two canals could still be seen in the 1970s, today there is no trace of the junction: neither the bridge nor the stop lock remain and the low embankment running west to the river has been removed. With the cessation of sand and gravel extraction on the other side of the valley south of Dunbridge about ten years ago, the conveyor belt that in part used the old railway and the small aggregates depot at Kimbridge Junction have also been removed.
Just over 100 yards from the junction, the canal crossed the River Test and several side streams on a four-arched brick aqueduct NG Ref: SU331263. WGS84: 51° 02′ 06″ N, 1° 31′ 44″ W.. The arches would have been very low as the surface of the water in the canal was only a few feet above the river. This aqueduct was demolished during the building of the Andover and Redbridge Railway in the 1860s. Old mapping suggests that one of the arches may not have been completely removed until the railway tracks were doubled in the early 1880s. The foundations of the brick piers were removed just after the Second World War by the river board.
West of the river, the canal was carried across the Test Valley on an embankment for about 700 yards (650m) and which can still be seen running south-westwards in amongst the trees. This substantial structure is still some 10 feet high at its highest and only pierced by the site of a two-arched aqueduct (demolished before 1871) where part of the River Test and the River Dun were both crossed NG Ref: SU327260. WGS84: 51° 01′ 59″ N, 1° 32′ 06″ W. near their confluence.
Near the crossing of a public footpath (the Test Way) and at the end of the embankment, in amongst the trees of Dene Wood, is the untraceable site of Lock 1 Approximate position NG Ref: SU325259. WGS84: 51° 01′ 55″ N, 1° 32′ 16″ W. which started the climb towards Salisbury. In less than 180 yards (160m) from the Test Way is the first crossing of the old canal by the railway to Salisbury NG Ref: SU323258. WGS84: 51° 01′ 53″ N, 1° 32′ 23″ W..
Having crossed the railway, the course of the waterway turns north-westward passing behind or through the back gardens of houses in Barley Hill, Dunbridge. The line of the canal crosses the railway twice more NG Ref: SU320260. WGS84: 51° 01′ 59″ N, 1° 32′ 41″ W. and NG Ref: SU319261. WGS84: 51° 02′ 01″ N, 1° 32′ 45″ W. immediately east of Dunbridge station (since 2006 called "Mottisfont and Dunbridge") and leaves railway property through the gate to the former goods yard. Crossing the road, the canal entered Dunbridge Wharf.
Dunbridge to Butt’s Green
From Dunbridge the canal followed the road to Lockerley lying between the lane and the River Dun. Joseph Hill’s estimate of 1794 for building the canal includes £80 “To Turning the Road at Dunbridge about 200 yards”. The dry canal bed can be easily seen along this section - sometimes during the winter it contains some water.
There are no visible remains of Lock 2, the site of which is said to be beneath the outbuilding at Dunnerley Cottage beside Lockerley Road. The rise in the road would tend to confirm this.
Several hundred yards after Lock 2, the course of the canal turns away from the road NG Ref: SU312258. WGS84: 51° 01′ 51″ N, 1° 33′ 20″ W., running just south of the river for nearly half a mile, but returns to the road NG Ref: SU306260. WGS84: 51° 01′ 59″ N, 1° 33′ 53″ W. just before The School Farm. The remains of the canal are present along much of this length. Again, Joseph Hill’s 1794 estimate refers “To Turning the River at Butt Green at the School Farm at Lockerly about 200 yards” at a cost of £150.
As the canal passes the farm, it has been infilled but to the west, for about 150 yards (140m), the bed is identifiable. One hundred yards before reaching Butt’s Green itself, a track runs northward from Lockerley Road and crosses the bed of the canal and fords the adjacent river with a footbridge accommodating a public footpath. There is no trace of any bridge crossing the course of the canal. This would have been a wooden lift (or draw) bridge.
Butt’s Green to Holbury Lane, Lockerley
The canal has been completely eliminated between the track and the railway embankment some 250 yards further on. The site of Lock 3 is not apparent either from old maps or on the ground but would seem to have been between the track and the railway. Some commentators have said that the lock was in what is now the garden of the house called Dunmeads. However, after examination of modern height data, it seems quite likely that the site of the lock is very near or even under the railway. The railway crosses the course of the canal about 130 yards west of the two arched bridge over the River Dun NG Ref: SU302264. WGS84: 51° 02′ 10″ N, 1° 34′ 13″ W.. On the north side of the railway, water in the canal is diverted into the river which in turn was diverted to pass under the bridge.
North of the railway line, the waterway contains flowing water and lies parallel to and west of the River Dun. The canal takes a substantial part of the combined flow of these watercourses. Although the canal takes some or all of the flow of the river in quite a number of places today, there is much evidence that the canal was originally engineered to be entirely separate from the river throughout its length from Kimbridge to West Grimstead.
Passing east of Lockerley’s parish church, St John’s, the watercourse swings westwards behind The Dennis Wooton Hall to arrive at a bridge under the East Tytherley road just north of its junction with the road to East Dean and adjacent to Lockerley Mill. This bridge is a replacement of the original canal structure.
From Lockerley Mill the canal runs in a generally westerly direction and to the north of the settlement at Lockerley Green and usually contains flowing water.
