Before urban development, the area was the estuary of the Wong Nai Chung river, which flowed through Happy Valley.

Bowrington Canal [yue; zh-tw] was built during the mid to late 1850s, fed by Wong Nai Chung.

Four years later, the flyover was expanded and extended south to the portal of Aberdeen Tunnel in Happy Valley[3] (the extension is separately named Wong Nai Chung Gap Flyover [yue; zh-tw]).

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.

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.
