東區海底隧道
In June 2005, CITIC decided to raise the toll for using Eastern Harbour Crossing from HK$15 to HK$25 for private vehicles and up to 67% for other classes of vehicles, under the fare adjustment mechanism derived from the build-operate-transfer (BOT) model. This increase aroused criticisms that the model was detrimental to the public interest, with the increase shifting more traffic to the already congested Cross-Harbour Tunnel.
