Before the redevelopment and reclamation in the surrounding area, Tiu Keng Leng could be reached by the winding, hilly and narrow Po Lam Road South, which ran past numerous busy quarries. At that time, Tiu Keng Leng's only public transport connections were Kowloon Motor Bus routes 90 and 290, served with minibuses, and by water transport. In 2001, with the redevelopment, a segment of Po Lam Road South was rebuilt and extended to near Kwong Tin Estate in Yau Tong. The reconstructed road was renamed O King Road and became the first road connection to modern Tiu Keng Leng.
