Drivers have been assured they will receive clearer information on real-time tolls at Hong Kong’s Western Harbour Tunnel, after a watchdog’s investigation identified shortcomings in the toll management system and inadequate staff training. To ease traffic congestion during rush hours, the government introduced time-varying tolls at the three cross-harbour tunnels, including the Western Harbour Tunnel, in December 2023. Different toll rates apply at different time slots, with charges gradually increasing to peak-hour rates during the transition periods and decreasing afterwards. In general, the toll rates change every two minutes during the transition time slots. AdvertisementToll amounts are calculated based on vehicle data and passage time records detected by the HKeToll toll points installed at the tunnels.
