將軍澳新市鎮
In the late 1980s, when the first two public housing estates in Po Lam, Tseung Kwan O New Town - Po Lam Estate and Tsui Lam Estate were built, it was the only link to Po Lam until the Tseung Kwan O Tunnel was opened in 1990. Nowadays, although Po Lam Road is no longer the main road to Tseung Kwan O, some bus routes from Tseung Kwan O still use Po Lam Road.
