To improve the east-west connectivity of the country, AECOM is responsible for providing detailed design of the final stage of Circle Line.


AECOM is appointed to oversee architectural services and design the civil infrastructure for nearly four kilometers of tunnel-alignment works.
To improve the direct east-west connectivity between the central east and central west areas, the proposed Circle Line Stage 6 (CCL6) will be built to close the loop of the existing Circle Line by connecting the Harbour Front station to Marina Bay station.
Expected to be completed in 2025, the CCL6 will allow commuters to enjoy a direct route between key employment areas in the Central Business District, upcoming developments in the Marina Bay area, and retail and office centres in the HarbourFront area.
