**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.
