西區海底隧道
The fourth harbour crossing is being proposed in Hong Kong as the fourth underwater tunnel to cross the Victoria Harbour to ease the traffic through the Cross-Harbour Tunnel. Even though the Western Harbour Crossing, operated by CITIC Pacific Limited, was built for this purpose, the tolls for crossing is triple the rates of the Cross-Harbour Tunnel, proving the Western Harbour Crossing ineffective in diverting traffic from the Cross-Harbour Tunnel. Around this time, a new tunnel between North Point and Kowloon Bay was suggested to relieve the stress on the Cross-Harbour Tunnel.
