Engineering Highlights

7.   Defu station is located along Tampines Road between Defu Avenue 1 and Defu Avenue 2 while Tampines North station is located between Tampines Link and Tampines Ave 11. Excavation works at these areas are expected to be challenging as the ground conditions comprise thick and soft layers of marine clay as well as a soil-like material comprising sandy and silty clay. Safety measures will be taken when carrying out the Earth Retaining and Stabilising Structure and deep excavation works to ensure stability of the ground and surrounding structures. LTA and the contractors will monitor the works closely to ensure that they are carried out safely and minimise any inconvenience to stakeholders.

8.   Construction works for Defu and Tampines North stations are expected to start in the second quarter of this year, with passenger service for CRL1 slated to commence in 2030.

About the CRL

9.   The CRL is Singapore’s eighth MRT line. It will serve existing and future developments in the eastern, north-eastern and western corridors, linking major hubs such as Jurong Lake District, Punggol Digital District and Changi region. The CRL will have almost half of its stations as interchanges with other rail lines, making it easier and more convenient for commuters to travel across the rail network.

10.  CRL1 is 29 kilometres long and comprises 12 stations from Aviation Park to Bright Hill^[1]. This will serve residential and industrial areas in Loyang, Tampines, Pasir Ris, Defu, Hougang, Serangoon North and Ang Mo Kio and benefit more than 100,000 households. With CRL1, common recreational spaces such as Changi Beach Park and Bishan-Ang Mo Kio Park will be more accessible by public transport. Studies on the details of subsequent CRL phases are ongoing.
