The Kowloon Bay section of the Central Kowloon Bypass is scheduled to open on December 6, 2026, when a flat HK$8 toll for all vehicles is also due to begin.
The Yau Ma Tei section opened in December 2025. The Kowloon Bay section will complete the bypass, linking roads in east and west Kowloon. Together with the existing tunnel connection to Tseung Kwan O, the route forms part of a road link across Tseung Kwan O, Kowloon East and Kowloon West.
Drivers will pay at a toll point at the eastern entrance to the Yau Ma Tei section, on the Kai Tak side. HKeToll will be used to collect the charge; installation and testing work for the system was due to finish in November.
The Transport and Logistics Bureau said two-way traffic on the Yau Ma Tei section had risen to about 75,000 vehicle movements. It forecast that, without a toll, peak-period use would approach saturation soon after the Kowloon Bay section opened, making a charge necessary to manage traffic.
At the HK$8 toll, the government forecasts that the bypass could divert about 20% of traffic from busy major roads in Kowloon, while leaving about 15% of its capacity available. It says the remaining capacity would help keep traffic flowing and accommodate future growth.
The Transport and Logistics Bureau said the toll was set with public affordability in mind and was expected to recover part of the route’s operating costs.
Once the connected route is complete, the government forecasts that peak-hour travel between Tseung Kwan O and Yau Ma Tei could fall from about 65 minutes to about 12 minutes.
