Singapore’s Land Transport Authority (LTA) has commenced civil construction works for Phase 2 of the Cross Island Line (CRL).
Acting minister for transport Jeffrey Siow officiated the ground-breaking ceremony at the site of the future CRL Clementi station.
Phase 2 of the CRL (CRL2), targeted for completion by 2032, will extend the 29km-long Phase 1 of the CRL by 15km westwards. CRL2 will comprise six underground stations. Two of the six stations will be interchange stations, with CRL King Albert Park station and CRL Clementi station connecting commuters to the Downtown Line (DTL) and East-West Line (EWL) respectively.
At 50m deep and extending to five basement levels, CRL King Albert Park interchange station will be Singapore’s deepest station. It will surpass the CRL Pasir Ris station which will be 47m deep and Bencoolen station on the DTL, currently the deepest underground station at 43m.
A 5km bored tunnel between CRL Bright Hill and CR14 stations through the Central Catchment Nature Reserve will be constructed using a 12.8m diameter TBM. The tunnelling works towards the CCNR commenced in May this year, along with ongoing ground improvement works.
LTA has awarded nine civil contracts for CRL2. They include the design and construction of tunnels between Maju station (CR16) and Clementi station (CR17) awarded to Sinohydro Corporation Ltd (Singapore branch); the tunnels between West Coast station (CR18) and Jurong Lake District station (CR19) to be built by Nishimatsu Construction Co Ltd – Okumura Corporation Singapore Branch Joint Venture; the design and construction of Turf City station and tunnels (CR14) and the tunnel between Fairways Drive and Sin Ming Walk awarded to Shanghai Tunnel Engineering Co (Singapore)/Obayashi Corporation Joint Venture; the West Coast station and tunnels to be completed by Gaumda Bhd Singapore branch; the design and construction of Maju station and tunnels by KTC Civil Engineering & Construction Pte Ltd; and the design and construction of Jurong Lake District station and tunnels to KTC Civil Engineering & Construction.
