China Railway S’pore branch bags $199m civil works deal for DTL2e tunnels

Construction will start in Q3 2026, with DTL2e service slated for 2035.

China Railway Tunnel Group Co. Ltd. (Singapore Branch) has been awarded the final civil contract by the Land Transport Authority (LTA) for the Downtown Line 2 extension (DTL2e), covering the design and construction of tunnels between Bukit Panjang station and the upcoming DE1 station.

The contract, valued at around $199m, involves twin bored tunnels about 1.8 kilometres long running beneath Woodlands Road and parts of the Kranji Expressway (KJE) flyover in a restricted work area near the existing station.

Construction is scheduled to start in the third quarter of 2026, with service on the DTL2e expected to begin in 2035.

To minimise disruption, works will largely be carried out outside operating hours, with ground stability monitored in real time and regular updates provided to residents and stakeholders.

China Railway Tunnel Group (Singapore Branch) specialises in tunnelling and infrastructure projects and is currently completing Prince Edward Station for Circle Line 6.

If you've been wondering whether SBR could work for your company — yes, probably.

A lot of the companies we partner with started as readers. They'd been following our coverage for a while, saw their own customers and competitors in it, and eventually asked the obvious question: could we do something with you? The answer is usually yes. The shape of it depends on what you're trying to do.

The options are broader than most people assume — thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. Some partners use one channel; most use a mix. We figure out the right combination by starting with your brief, not with our rate card.

So if the question has been on your mind, here's the easy way to ask it.

We'll tell you honestly whether we can help, and how. It's a better use of everyone's time.
