Upper Thomson Clears

We look at Contract T212 which oversees the construction of Upper Thomson station as well as twin bored tunnels between UTS and CDT stations. About 1/3 of the marked trees to be cleared have already been chopped, while utility diversions are still underway as of today.

More information will be released upon commencement of construction. T212 will see the construction of 2 main C&C structures - Upper Thomson Station (UTS) and Upper Thomson Launch Shaft (ULS). The launch shaft will be an isolated structure built between UTS and Caldecott stations, located directly beneath the existing Upper Thomson Road, in front of Shunfu Gardens. A road diversion within the next few months would be necessary to facilitate the shaft and subsequently tunnel works. A single TBM will launch twice from ULS to UTS while 2 TBMs bore towards CDT. The site office is being constructed infront of Shunfu Estate.
