Part of Route 5, it is a dual two-lane carriageway viaduct running from the western exit of Kai Tak Tunnel near Sung Wong Toi Road [yue][clarification needed] to its ramp on Chatham Road North between Lo Lung Hang Hill [yue] and the western side of Hung Hom, to the northnortheast of Fat Kwong Street Flyover.

[2][3] In this sense, East Kowloon Corridor serves as an alternative for drivers since it has only two exits[clarify] and no traffic lights.

[5] Just ahead of the entrance to Kai Tak Tunnel lies the only branching exit of East Kowloon Corridor, which goes to Kowloon City Road northbound from the northbound direction, San Shan Road eastbound from the southbound direction, and the only branching entrance to the southbound direction fed from San Shan Road westbound.

[5] It descends and joins into Chatham Road North near an intersection with Fat Kwong Street.

[6] 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.
