Construction

The tunnel was given the name "Cheung Ching" (長青) because it is beneath Cheung Ching Estate, the first public housing estate on the island.

Construction through the granite of Tsing Yi Peak required explosives to get through the hardness of the hill. To prevent dislodging of rocks and buildings on the surface slopes the rocks were reinforced by concrete and steel. Although the tunnel used explosives in its construction, boring was more used as the primary digging procedure.

Management

The tunnel was managed by Tsing Ma Management Limited under Tsing Ma Control Area, along with Tsing Ma Bridge, Kap Shui Mun Bridge, Ting Kau Bridge, Rambler Channel Bridge, North Lantau Highway and Tsing Kwai Highway.

The traffic of the tunnel is monitored in the buildings at both end, namely East Portal and West Portal Buildings.
