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.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
