Expo Bound Tunnel Completes

The last frontier of the 42km long Expo Bound tunnel for the entire Downtown Line have just been successfully broken through at Tampines West station. The TBM went through an arduous journey during its first drive towards Bedok Reservoir. 3 months of reassembly works were done at the Prison Shaft prior to the commencement of the second drive towards Tampines West. The breakthrough marks the retirement of the machine on the MRT project, as well as a complete linkage to the network of underground tunnels within the Downtown Line.
