DTL3 Tunnels 75% Complete

Tunnelling works for the entire Downtown Line is beginning to wrap up with more than 60% of the 40 breakthroughs for DTL3 achieved thus far. Penta Ocean at C933 in particular was able to coordinate the docking of all 4 TBM machines within a span of just a month. Due to difficulties, we are unable to update C926 at this moment. It is expected that all 4 TBMs have been already re-driven, in which we will confirm at a later date. The final TBM launch is expected to be undertaken by GS, for the second launch out of Tampines East station in September 2014.
