The Eastern Harbour Crossing, abreviated as "EHC" is a tunnel in Hong Kong. It is a combined road and MTR rail link under Victoria Harbour between Quarry Bay in Hong Kong Island and Cha Kwo Ling in Kowloon.
The tunnel is branded by the operator, New Hong Kong Tunnel Company Limited, as Eastern Harbour Tunnel, although the government refers to the tunnel itself as Eastern Harbour Crossing and the legislation governing the tunnel is known as Eastern Harbour Crossing Ordinance.
The rail part connects Quarry Bay and Yau Tong stations of the MTR Tseung Kwan O Line. The road part connects Island Eastern Corridor and Kwun Tong Bypass.
In June 2005, the toll for using Eastern Harbour Crossing was raised from HK$15 to HK$25 for private vehicles and much more for other classes of vehicles. This has aroused dissatisfaction of the general public and shifted more traffic to the already congested Cross-Harbour Tunnel. The Government has looked at solutions to this and has included: raising the toll on the Cross-Harbour Tunnel, extending the franchise on the Eastern Harbour Crossing to allowing the owners more time to make a return on investment, merging the three tunnels into one management company or buying back the tunnel.
