The Transport Department (TD) reminded the public today (May 4) that the HKeToll, a free-flow tolling service, will be implemented in the Tsing Sha Control Area (TSCA) (Eagle's Nest Tunnel, Sha Tin Heights Tunnel and Tai Wai Tunnel) from 5am this Sunday (May 7). Motorists can drive through the TSCA toll plaza without having to stop or queue at toll booths for payments. Tunnel tolls will be collected through toll tags and all manual toll booths and Autotoll lanes will be cancelled.
