The Shing Mun Tunnels are a system of tunnels and viaducts in the New Territories, Hong Kong connecting the new towns of Tsuen Wan to the west and Sha Tin to the east. They are a part of Route 9 and the Tsuen Wan entrance is the reset point of Route 9.Construction started on 11 February 1987 and the tunnels opened on 20 April 1990. They are made up of three sections, each with twin two-lane tunnels. The westerly pair passes through Smuggler's Ridge near Shing Mun Reservoir, where it gets its name from; the easterly pair passes through Needle Hill and is linked to the westerly pair by two viaducts over Lower Shing Mun Reservoir. The toll plaza and bus interchange are located outside the Tsuen Wan end of the tunnel.
The tunnels lead to Cheung Pei Shan Road and connect Wo Yi Hop Interchange in Tsuen Wan, and Shing Mun Tunnel Road in the east which links Tai Wai Road and ends at Tai Po Road.
