Woodlands North Earthworks

Woodlands North station sits on one of the most hilly terrains across the island. As such, terracing works are needed to flatten the existing land before structural works can begin. The granite obtained from the blasting works during the earthworks and excavation process will be recycled into composites for concrete to be used back when constructing the station, in the effort to minimize project cost. 

The cut and cover portion for the contract is extremely long (750m) due to the presence of a north and south crossover, as well as an abutting overrun tunnel for the Changi Bound track which will be constructed beyond Admiralty Road West. A road diversion will be needed.

ULS - Preparations to Divert

Works are in full swing for the staging of one of the biggest road diversions to be implemented along the corridor of the Thomson Line. Road surfacing has begun for the new Upper Thomson Road that will swing round the existing road which will be excavated up for the Upper Thomson Launch Shaft (ULS). The new POB has already been launched up this week.

The diversion will take place on Sunday, September 14 and would last throughout the entire duration of the tunnelling phase of the project, estimated to be completed in 2019.

Night photos updated on August 29.

Dickenson Hill Road Closes

Dickenson Hill Road, a small lane connecting Kreta Ayer Heights to South Bridge Road, will close from this Sunday, July 27 till project completion in December 2020. Situated at the center of the T223 site, this closure is necessary for the construction of the Maxwell station. Outgoing traffic shall be diverted to Sago Lane during the construction phase.

Hock Lian Seng has taken over possession of the site at Maxwell, with hoardings erected, crawler crane and silos arriving on the site. Due to the tight space constraints, the platforms will be stacked here.
