To relieve the issue of congestion, the idea of constructing an elevated vehicular corridor in the Eastern District was brought out in 1968, as part of the "Hong Kong Long Term Road Study". The original plan was to construct an elevated dual carriageway above King's Road, which continues eastward as a ground-level road along the coastline between Sai Wan Ho and Chai Wan. Such an alignment along King's Road was later discarded in favour of a waterfront viaduct running parallel to King's Road. It was not until 8 April 1981, 20 May 1982 and 5 August 1986 that construction commenced on the three sections of the corridor, respectively. The corridor was opened in three phases: Causeway Bay to Taikoo Shing on 8 June 1984; Taikoo Shing to Shau Kei Wan on 26 July 1985; and Shau Kei Wan to Chai Wan on 12 October 1989.
