Bright Hill - POB launch

The 2 replacement POBs for the project were launched at Ang Mo Kio Avenue 3 and Upper Thomson Road in August and September respectively. The new bridges are simply spanned with staircases re-positioned to avoid the tunnel alignments leading up to the Bright Hill station. TBM 2 is progressing on its initial drive to Upper Thomson and the other 3 TBMs are being assembled up in the launch shafts. 

Another realignment of Sin Ming Avenue took place earlier this quarter to facilitate the final stretch of secant bored pile works south of the station box. Excavation and basement RC works have commenced at entrance B.
