Singapore begins Circle Line 6 tunneling works

Singapore’s Land Transport Authority (LTA) launched on July 25, the tunneling works for Circle Line Stage 6 (CCL6) which is scheduled to enter services in 2025. The Tunnel Boring Machine will tunnel from Keppel station to CCL Harbour Front station and other two TBMs are expected to be launched in September and October. Currently, 66% of earth retaining and stabilising structure works have been completed, and excavation and structures’ construction works are progressing well.
Construction of the three CCL6 stations – Keppel, Cantonment and Prince Edward Road stations, as well as the expansion of Kim Chuan Depot commenced in 2017. Works are progressing smoothly and are expected to be completed by 2025.
The Circle Line Stage 6 (CCL6) is expected to enter services in 2025 offering a direct route between areas in the west, such as Pasir Panjang and Kent Ridge, and key employment areas in the CBD, as well as upcoming developments in the Marina Bay area.
The 4-km CCL6 closes the loop for the CCL by connecting HarbourFront Station to Marina Bay Station. When the section will be operational, the CCL will have a total of 33 stations with 12 interchanges to connect to all existing MRT lines and the future Thomson-East Coast Line.
LTA is also purchasing 12 new trains from Alstom to cater for the expected increase in passengers when the CCL is fully operational. These trains will be delivered progressively from 2024 and are in addition to the 11 trains that were procured in April 2018 for CCL6. When these 23 trains are delivered, the total CCL fleet size will increase by 36% to 87 units.
