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.

The toll plaza and bus interchange are located outside the Tsuen Wan end of the tunnel.

[4] The tunnels were formally inaugurated by Governor David Wilson on 19 April 1990.

[5] The Hong Kong Government awarded a number of contracts for the construction work, including one awarded to Philips Hong Kong Ltd. Philips' completion of the work was delayed, incurring damages due to the government.

The wording of the contract in relation to liquidated damages was addressed in various courts and the interpretation of the wording was ultimately addressed by the Privy Council of the United Kingdom, who ruled in favour of the government.
