car crossing. After just three and a half years of operation, the operator had recouped the construction costs. In 1984, the Hong Kong Government introduced a tax in addition to the operator's toll to make the overcrowded tunnel less priced. The price for a car transit was now HK$10. In 1993, an electronic toll collection system was installed. Together with measures to control the flow of traffic, the vehicle capacity could be increased. It was administered by The Cross-Harbour Tunnel Company Ltd until August 1999, when the operation franchise agreement expired and the government assumed control. From 1 November 2010, the tunnel was managed, operated and maintained by Serco on a contract basis. The tunnel is currently operated by Chun Wo Tunnel Management Limited, which was awarded a contract lasting from 2016 to 2022. The 2017 Hong Kong action film Shock Wave, starring Andy Lau, set its main plot in the tunnel. In November 2019, Hong Kong protesters set roadblocks across the northern tunnel entrance and set fire to tollbooths, as many roads around the Polytechnic University were blocked, leading to the closure of the tunnel for a dozen of days. Fees The tunnel generates approximately HK$700 million in annual toll revenue. Transport , there are 44 bus routes passing through the tunnel.
