These were in turn replaced by double-ended, screw-driven ferries in 1904. Both passenger and vehicle ferries operated on the Devonport run until the opening of the Auckland Harbour Bridge in 1959. Immediately after the opening of the bridge, passenger ferry services to other North Shore destinations (such as Northcote and Birkenhead) were cancelled, as were all vehicular ferries. The Devonport passenger ferry was retained on a much reduced timetable. The majority of the ferries were scrapped, only a handful being retained until being replaced by more modern vessels. The last of the old-style double-ended ferries, the diesel-engined "Kestrel" (built in 1905), was retired from the commuter run in 1988 and was then operated for cruises and sightseeing.
