Wong Nai Chung Gap
Canal Road Flyover () was built in the 1970s for the Cross-Harbour Tunnel, between Canal Road East and Canal Road West. Many who do not know the history of Canal Road might associate the flyover with "Ngo Keng Kiu". It initially connected only Canal Road West to the north of Gloucester Road when it opened on 29 March 1972. Four years later, the flyover was expanded and extended south to the portal of Aberdeen Tunnel in Happy Valley (the extension is separately named Wong Nai Chung Gap Flyover).
