Mandai Depot - TBM 3 Breakthroughs

The first Earth Pressure Balance TBM for the line broke through the retrieval point north of Mandai Depot last Saturday, completing the reception tunnel 3 drive from the launch shaft 1 (LS1). This is the fifth bored tunnel to be lined for the line, and is also the shallowest breakthrough point in the MRT construction history due to the unique utilization of TBMs for the construction of the reception tunnels leading to an at-grade depot.
