This short canal, less than a mile long, connected Lough Corrib to the sea at Galway. It had two locks, including a sea lock, five swivelling bridges and a substantial canal basin. It was abandoned in 1954 when the swivelling bridges were replaced by fixed bridges. The last vessel down the canal was the Amo II, a 90' motor yacht sold by the Guinness trustees to a Galway hotelier.
