The tunnel, between Ting Kau and Yuen Long, will be closed for about 5 minutes from 0.00am on May 31, after which new time-varying tolls will be in place.
It will then shut again for two hours from 3am, with HKeToll then coming into operation and the manual toll booths closing down.
Instead of the present fixed toll of HK$58, private cars will be charged HK$45 during peak hours, HK$30 during regular periods and HK$18 at quiet times from Monday to Saturday.
A flat toll of HK$18 will apply to private cars throughout the entire day on Sundays and public holidays.
The fees for motorbikes will range from HK$7.2 to HK$18.
Taxis will be charged HK$28 on any day, while there will be a flat-rate fee of HK$43 for trucks and buses.
“New tolls for all vehicle types will be lower than current tolls by 22 to 80 percent,” the government said.
Deputy Commissioner for Transport Patrick Ho said he doesn’t think they are rushing the introduction of the electronic toll collection system at the tunnel.
“We hope to implement HKeToll as soon as possible to provide convenience to drivers and passengers travelling from New Territories West to the urban area,” he said.
“Therefore, we have decided to implement e-tolling on the same day we take over the Tai Lam Tunnel. This arrangement is slightly different from previous practices.”
Officials say the new tolls should make use of the tunnel’s spare capacity and alleviate congestion on alternative routes such as Tuen Mun Road.
