East Kowloon Corridor (; aka East Kowloon Way) is a motorway in Kowloon, Hong Kong. Part of Route 5, it is a dual two-lane carriageway viaduct running from the western exit of Kai Tak Tunnel near to its ramp on Chatham Road North in Hung Hom, near where Ma Tau Wai Road joins the latter. Description Since its completion in 1981, East Kowloon Corridor, together with Airport Tunnel (renamed Kai Tak Tunnel after the airport in 2006 was closed in 1998), play a crucial role in diverting road traffic in Kowloon by feeding traffic between Hung Hom and Kwun Tong by providing a shortcut, thereby avoiding causing traffic congestion in To Kwa Wan, Mong Kok, Kowloon City and Ngau Chi Wan where traffic is already saturated.

The word "East" is used in order to disambiguate from West Kowloon Corridor, which is situated farther west near Lai Chi Kok. Furthermore in the earlier decades, To Kwa Wan and Hung Hom both lied in the eastern half of Kowloon Peninsula with the British Section of the KCR serving as the boundary, and the area now known as East Kowloon was part of New Kowloon. However, the entire peninsula is now integrated into West Kowloon. Effect on surroundings As many buildings were already built around Kowloon City Road and Ma Tau Wai Road before East Kowloon Corridor was constructed, residents in the district, especially those living in lower floors of buildings on the sides of the flyover, were strongly affected by the noise generated from car engines during rush hour.
