On 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 Nullahs 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.
