Kai Tak Nullah

It flows from Po Kong Village Road along Choi Hung Road, pass Tung Tau Estate and San Po Kong, into Kai Tak Development Area before discharging into the Victoria Harbour at the Kwun Tong Typhoon Shelter.

In January 2005, the Drainage Services Department announced plans for nullah-covering works for 16 nullahs, at the cost of 1.2 billion Hong Kong dollars.

These included a plan to cover up part of the Kai Tak Nullah along Choi Hung Road, starting in 2010 and finishing by 2014.

The Traffic and Transport Committee of Wong Tai Sin District Council demanded a faster timetable, in order to launch the greening work and widen Choi Hung Road.

As the water quality improved, at the urging of the pro-Beijing political party Democratic Alliance for the Betterment and Progress, the Federation of Trade Unions, and environment concern group Conservancy Association, the Civil Engineering and Development Department launched a feasibility study on turning the nullah into Kai Tak River.
