The Portsmouth and Arundel Canal was a canal in the south of England that ran between Portsmouth and Ford in the Arundel district. It was built in 1823 but was never a financial success and was abandoned in 1855; the company was wound up in 1888.
Chichester Ship Canal
The Chichester Ship Canal ran East from the sea lock at Birdham to the junction of the Chichester and Arundel Canal (known more commonly as the Portsmouth & Arundel Canal) at Hunston and then north to a basin (Southgate Basin) in the south of the city of Chichester. There were 2 locks at Milton, a sea lock and an upper lock.
The tidal channels
The Portsea section was connected to the rest via a 13-mile channel dredged through Chichester Harbour, past the southern side of Thorney Island (original plan was to go around the northern side) and to the north of Hayling Island, and finally across Langstone Harbour. Off Goldsmith Avenue, the east-west route of the canal can still be traced by more recent residential development along Old Canal and Towpath Mead roads. The tow-path follows the course of the foot-path just north of the caravan site and allotments on the south side of Locksway Road at its easternmost end, with the canal to the north side of this. There is evidence that the canal was filled in here with coke from the local gas works. The remains of the lock into Langstone Harbour are also still in evidence. The lock has been a conservation area since 1977 and is a grade II listed structure.
