The Eastern Harbour Crossing (Chinese: 東區海底隧道), abbreviated as "EHC" (Chinese: 東隧) is a combined road-rail tunnel that crosses beneath Victoria Harbour in Hong Kong. Opened on 21 September 1989, it is the second harbour-crossing tunnel built and the longest amongst the three. It connects Quarry Bay on Hong Kong Island and Cha Kwo Ling in Kowloon East.
