With the rapid development of the new towns, the tunnels have already reached its saturation flow just like Cross-Harbour Tunnel. The flow was eased by other tunnels being put into service later, such as Shing Mun Tunnels, Tate's Cairn Tunnel, Tsing Sha Highway. Nonetheless the convenience of its connection and directness, with a lower fee than the Tate's Cairn Tunnel, Lion Rock Tunnel contributes to the highest daily average vehicles flow of all non-harbour-crossing tunnels. 90,608 vehicles used the tunnels everyday on average in 2014.
