Another Milestone Reached for the Johor Bahru – Singapore Rapid Transit System Link Viaduct

News Releases 24 Mar 2023 Rapid Transit System (RTS)

        The Land Transport Authority today commemorated the pile caps installation works in the Straits of Johor on the Singapore side, for the Johor Bahru – Singapore Rapid Transit System (RTS) Link project. The event, officiated by Minister for Transport S Iswaran, marks another milestone in the project and the next phase of works for the installation of the rail viaduct structure of the RTS Link. 

2          The pile caps, including 161 bored piles, serve as the foundation of the RTS Link viaduct in the Straits of Johor, on the Singapore side. The diameter of each pile is typically two metres and is installed at an average depth of 30 metres. Once at the required depth, each pile is filled with concrete before the pile cap is casted over the piles.

3          A total of 12 pile caps will be installed on the Singapore side to form the foundation for piers which support the rail viaduct structure on land and on sea/over water. Once all the piers are completed, the launching of the viaduct segments will commence. The 730-metre viaduct (on the Singapore side) will be made up of 207 segments, with each span length ranging from 50 metres up to a maximum of 110 metres.

4          The RTS Link viaduct stands at a height of 25 metres above water level in the middle of the Straits of Johor. On the Singapore side, it transitions gradually to underground tunnels connecting to the RTS Link Woodlands North station.

5          The RTS Link Woodlands North station will be constructed underground at a maximum depth of 28 metres. There will be three storeys, with two basement levels and an underground B3 linkway to the CIQ building. The RTS Link Woodlands North station and CIQ building are approximately 10 times the size of a typical MRT station. These facilities will be adjacent to the Thomson-East Coast Line (TEL) Woodlands North MRT station and be seamlessly connected via an underground concourse. Construction works for the CIQ building, tunnels and viaduct started in 2021. Works are progressing well and on target to achieve timely completion.

About RTS Link

6          The RTS Link is a 4-kilometre rail shuttle service between the Singapore terminus at Woodlands North station and the Malaysia terminus at Bukit Chagar station in Johor Bahru, with a capacity of up to 10,000 passengers per hour in each direction. Passengers will enjoy a fast and seamless experience travelling between Singapore and Johor Bahru on the RTS Link, and a train journey time of about five minutes between the two stations. The CIQ facilities of Singapore and Malaysia will be co-located at the Woodlands North and Bukit Chagar stations, which means that passengers only need to clear the immigration authorities once, i.e. at their point of departure. When the RTS Link opens for service at the end of 2026, it will be a game changer that will significantly improve connectivity between Singapore and Johor Bahru, and ease congestion along the Causeway.
