Very little remains of the Southampton Branch of the canal, and in 1966 Edwin Welch produced a small book for the Southampton Records Office, the research for which included the production of annotated maps, based on 2.5-inch Ordnance Survey maps from the 1930s, to document the route. Development was rapidly obliterating what few remains there were even then. The branch from the Test started close to God's House Tower, which at the time was on the bank of the river. This area has changed a great deal, with reclamation of land for the ferry terminal. From there it headed due north. The street names of Canal Walk and Lower Canal Walk give some clues to the route, but the canal was filled in haphazardly in the middle of the nineteenth century, and was then built over. The street plans were altered significantly after the Second World War, when Queensway was built. When the Palmerston House housing project was being built on Queensway in 1961, excavations for the foundations located part of a wharf, but no drawings were produced before it was buried beneath concrete.
