The next section of the canal lies beneath the northern part of the Southampton Central railway station site, but there is a small area of woodland to the north of the railway line about to the west of the station, where remains of the canal bank were still discernable in 1966. To the west, the railway and the Millbrook Trading Estate have destroyed the route, which was either under or just to the north of the railway tracks. In 1964, when the Tanners Brook flood relief scheme was being constructed, a six foot wide brick arched culvert which carried the brook under the canal was unearthed by the Hampshire Rivers Board, the bed of this section of the canal being recorded as lying above the nearby high water mark and fed from the local streams it crossed. The culvert was subsequently filled with concrete. Some to the east of Redbridge station, the route crossed to the south of the railway line, to run along the bank of the Test. This area has been altered by reclamation of the mudflats and the construction of the Prince Charles container port. The route of the canal here was marked on the 1871 Ordnance Survey map, and much of it still appeared on the 1961–68 edition, some 90 years later. Railway sidings to the south of Redbridge station, now lifted, gradually destroyed the western end of this section, while the eastern end was filled in by the Docks Board between 1963 and 1965. The small section that remained between the two was pumped out by the Southampton Auxiliary Fire Service in 1966 so that it could be measured and recorded.
