The controversial Central-Wan Chai Bypass is set to open soon – after nine years and HK$36 billion, we are finally getting the “missing link” in east-west traffic movement along the north shore of Hong Kong Island.

This is not just a major highway connection. It also creates enormous opportunities to transform traffic priorities and rethink how best to use our limited road surfaces in a packed part of the city.

The first opportunity is rationalisation of cross-harbour tunnel flows. Traffic studies over the years have shown that better use of the tunnels and changes in tolls would only be effective once the “missing link” was in place. It is great to see that Chief Executive Carrie Lam Cheng Yuet-ngor made this a top priority in her policy address and has negotiated a deal with the Western Harbour Tunnel for some equalisation of tunnel fares – if the Legislative Council agrees (and they should, considering all the benefits that would arise).
This is not just a question of tunnel charges. It is how to use limited road infrastructure efficiently and reduce other costs – such as time in congestion and the costs of air pollution. However, it is disappointing to see that the smart city initiative has not been applied to the proposed tunnel charging system. Available technology could be used for variable tolls.

Indeed, the tunnels should be seen as an opportunity for congestion charging, where different tolls can spread traffic better. Higher charges during the day could be softened by low charges at night, encouraging private car owners to avoid rush hours, and off-peak commercial deliveries, with public transport given priority at peak hours.

The second opportunity is to encourage better use of existing road space by redistributing traffic. The bypass must be used to remove through traffic from Connaught and Gloucester roads. This would create a chance to reduce traffic on local roads such as Hennessy Road and Des Voeux Road Central. The simple removal of long-haul bus routes from these inner roads out to the bypass and to the new roads on the Central and Wan Chai reclamation areas will result in more efficient and quicker bus journeys. Moving congestion out leaves space to create a much better city centre. The removal of vehicles leaves room for wider footpaths, more space for people, and for greening and tree planting.
