Alignment and stations announced for Singapore’s CRL3

Singapore’s Land Transport Authority (LTA) has announced the alignment and station locations for the Cross Island Line Phase 3 (CRL3).

CRL3 will extend the CRL westwards from CR19 station in Jurong Lake District to CR23 station at Gul Circle, improving rail connectivity in Singapore’s western region and cutting travel times. 

CRL3 is approximately 10km and comprises four underground stations – CR20, CR21, CR22 and CR23. Two of the four stations will be interchange stations, with CR21 station connecting commuters to the Jurong Region Line at JS12 station, and CR23 station connecting to the East-West Line at Gul Circle station.

Together with other ongoing rail expansion projects, CRL3 will expand Singapore’s rail network to more than 360km. 

As part of CRL3, a second CRL rail depot of approximately 23ha will be constructed at the former Raffles Country Club site to provide maintenance facilities and stabling for the CRL train fleet. This will be co-located with a multi-storey bus depot.

Construction works for CRL3 are expected to commence in 2027, with the stations targeted to open by the late 2030s. Noise and vibration impact studies will be conducted prior to the commencement of CRL3 construction works. LTA will engage and work closely with stakeholders to implement comprehensive mitigating measures to address construction noise, dust, safety and traffic concerns. 

The government will need to acquire seven industrial properties and partially acquire another eight for construction of the new line.

When complete, the 67km CRL will be Singapore’s eighth and longest fully underground MRT line. It will serve existing and future developments in the eastern, western and north-eastern corridors, linking major hubs such as Changi, Punggol Digital District, Jurong Lake District, and Tuas. It will also provide additional alternative travel, reducing crowding on other parts of the rail network.

It is expected to have a daily ridership of at least 600,000 in the initial years, growing to one million in the longer term. 

CRL1 is approximately 29km long and comprises 12 stations.  Construction works are well in progress and is expected to be completed by 2030.

The CRL-Punggol Extension, which is around 7km long and comprises four stations, is targeted for completion in 2032.

CRL2 spans around 15km with six stations, and is due to be completed in 2032.

Works are also under way for an approximately 6km extension from CR2 station to CR1/TE32 station at Changi Terminal 5.
