西區海底隧道
Due to severe congestion experienced at the Cross Harbour Tunnel and the feeder roads to the WHC, there have been calls for lower tolls at the Western Harbour Crossing by letting the Government of Hong Kong buy back the tunnel from the current owners of the tunnel, WHTCL, so that it can control tolls and ease traffic congestion in the Cross Harbour Tunnel area. To that end, lawmakers passed a non-binding motion in 2008 for the HK Government to address the situation. However the consultant hired by the Government to find a solution to the traffic problem did not suggest the Western Harbour Crossing have lower tolls. The consultants said that lowering tolls would result in a very high increase in traffic volume, with severe congestion on the exit to Route 4 during rush hour. This solution would only be possible when the construction of the Central–Wan Chai Bypass is completed.
