Before urban development, the area was the estuary of the
Wong Nai Chung river, which flowed through
Happy Valley. The 4th
Governor of Hong Kong,
John Bowring, developed the estuary area and named it (or Bowring City). was built during the mid to late 1850s, fed by
Wong Nai Chung. Because the long and narrow
canal resembled the neck of a goose it was known as
Ngo Keng Kan (). It was used by small vessels that could pass under various bridges along the route. The landmark across the canal, built in 1861, was known as
Ngo Keng Kiu () and carried the
Hong Kong Tramways line across the waterway. The surrounding area, Bowrington, is also known as
Ngo Keng. The original wooden bridge was replaced by an iron one that opened in March 1892. During the
reclamation from 1922 to 1929 that created modern
Wan Chai (the
Praya East Reclamation Scheme) a wider bridge (100 foot width) was built with a double line of tram tracks. The canal was covered and made
subterranean in the 1970s when the
Canal Road Flyover was built. However, the name survives for the area. ==Canal Road Flyover==
