Marina South - TBM Assembly

The 38th and final TBM for the Thomson stretch of the line has finally been lowered and is being assembled at the launch shaft. The CREG EPBM will drive the 750m Woodlands Bound tunnel towards Marina Bay first. Structure of the station continues to be cast, with installation of rebar ongoing at the roof slab level at the highest point. 

Marina Boulevard has been realigned back for shoring and excavation works to proceed for the interconnecting section between the station and cut and cover tunnel. Realignment of Marina Grove is being prepared for similar works to be carried out at the T228 interface.
