Tsing Kwai Highway (Chinese:青葵公路; pinyin:Qīngkuí Gōnglù; Cantonese Yale:ching1 kwai4 gung1 lou6) 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 3 km dual-4 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 (or Rambler Channel Bridge), and ends at its junction with the Cheung Ching Tunnel. Tsing Kwai Highway was opened on 19 February 1997.
