Bowrington Canal [yue; zh-tw] 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 (鵝頸澗; 'goose neck stream'). It was used by small vessels that could pass under various bridges along the route. The landmark Bowrington Bridge [yue; zh-tw] across the canal, built in 1861, was known as Ngo Keng Kiu (鵝頸橋; 'goose neck bridge') 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.[1]
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.[2]
The canal was covered and made subterranean in the 1970s when the Canal Road Flyover was built. However, the name survives for the area.
Peter Hines[4] was the Resident Civil Engineer for the building of Happy Valley's multiple-curves, 4-lane-wide, 40-span-long viaduct, and roads – and responsible for the opening in late 1980. He had warned that the wide, sloping roads would flood rain into the Happy Valley Racecourse and harbour tunnel, requiring flood tanks hidden under the racecourse.[5]
The flyover was expanded again and an exit connected to Canal Road East.[when?]
The area under this flyover was once visited by the second installment of Canadian television reality competition series, The Amazing Race Canada, where the U-Turn of the third leg was located.
Villain hitting
The area under the Canal Road Flyover, adjacent to Hennessy Road, is known for the old ladies who offer villain hitting services, in which personal enemies are cursed by beating pieces of paper representing them. The practice is especially popular during king chat (ging jat) (typically in March).
