MTR re-proposed the line in 1993, and the plan was approved by the Hong Kong Executive Council on 20 October 1998. Construction commenced on 24 April 1999 and the line opened on 18 August 2002, at a cost of HK$18 billion. The new line took over the cross-harbour segment, via the Eastern Harbour Crossing to North Point station, from the Kwun Tong line. The Kwun Tong line was extended to Yau Tong and Tiu Keng Leng stations to interchange with the new line.
