SINGAPORE – The local branch of a Chinese firm has clinched the final civil contract for the second extension of the Downtown Line (DTL), with the total cost for the entire project amounting to about $1.26 billion.
The final contract, worth an estimated $199 million, will see China Railway Tunnel Group design and construct tunnels between the existing Bukit Panjang station and the upcoming DE1 station in Sungei Kadut Avenue, the Land Transport Authority (LTA) said on March 16.
Measuring about 1.8km in length, the set of twin tunnels will be built beneath Woodlands Road and will run through infrastructure such as the Kranji Expressway. Work is slated to begin in the third quarter of 2026.
To minimise the impact on existing railway structures and commuters on the DTL, LTA said it will coordinate with different agencies and operator SBS Transit to ensure that sensitive works are carried out when the line is not operating.
It added that the tunnel construction will also occur within a limited space due to the proximity to Bukit Panjang station.
