Singapore’s Land Transport Authority (LTA) has started construction of the Cross Island Line (CRL) Phase 1. On January 18, a groundbreaking ceremony was held at the site of his future CRL Brighthill station, officiated by the Minister of Transport, Mr S Iswaran. .

At 50km in length, the CRL will be Singapore’s eighth and longest fully underground metro line, connecting major hubs such as Jurong Lake District, Punggol Digital District and Changi. The line, which will open in three phases, is expected to carry more than 600,000 passengers per day when the first phase opens in 2030, and eventually he is expected to grow to more than one million.

CRL Phase 1 spans 29 km and has 12 stations from Aviation Park to Bright Hill, including East-West Line Pasir Lis Station, North-East Line Hogan Station, North-South Line Ang Mo Kio Station and interchange with Thomson East Coast .Bright Hill station line. LTA is CRL Phase 2 Bidding BeginsComprised of six stations from Turf City to the Jurong Lake District, Phase 3 of engineering research is underway.

The Bright Hill station will also connect to a new 2km Transit Priority Corridor (TPC) along Sing Min Avenue, including dedicated bus lanes, new cycle paths and widened sidewalks. When the TPC is fully completed in his 2029, Xinming district residents will have more travel options to reach recreational spaces such as Bright Hill MRT station and Bishan Ang Mo Kio Park.

CRL employs various technologies to improve construction efficiency and safety. These include virtual and augmented reality tools to enhance functionality and facilitate coordination. Productivity is further enhanced through platforms such as computer simulations of various operational scenarios at Changi East Depot.

A 12.6m-high large-diameter Tunnel Boring Machine (TBM) is used to construct tunnels for various sections between CRL stations, such as between Air Park Station and Luoyang Station. Each tunnel has two lines of his. This is the largest tunnel boring machine to be deployed on the LTA rail project and is expected to increase the productivity of the work and reduce the manpower required.

At Teck Ghee Station, a rectangular TBM will be used for the construction of the underground passage. To improve overall construction productivity and safety, contractors employ closed-cut construction methods to minimize ground subsidence. Other innovative construction methods will be used to improve overall construction productivity and safety, LTA said.

CRL trains stop at the 57-hectare Changi East Depot near the Changi Exhibition Centre. The depot will include an operations management center and maintenance facilities for up to 70 of his CRL trains, and will be fitted with photovoltaic panels to generate renewable energy for depot operations.
