Tsing Kwai Highway is a section of Route 3 in Hong Kong, previously known as Route 3 - Kwai Chung Section. From its junction with West Kowloon Highway at Mei Foo Roundabout, the expressway runs in the form of a three-kilometre dual-four-lane viaduct atop Kwai Chung Road and Kwai Tai Road, circumscribing the container terminals to reach the Rambler Channel. Then, the highway crosses the channel along a 500-m bridge known as Cheung Tsing Bridge, and ends at its junction with the Cheung Tsing Tunnel. Tsing Kwai Highway was opened on 19 February 1997.
