SINGAPORE’s Land Transport Authority (LTA) has awarded a $S 526m ($US 386.4m) civil contract for the design and construction of Bright Hill interchange station and tunnels under Cross Island Line Phase 1 (CRL1) to Penta Ocean Construction.

This is the last of 12 civils contracts to be let for CRL1. Construction will commence in the second quarter of this year with passenger services expected to begin in 2030.

The station is located in an area where the ground is made up of predominantly Bukit Timah Granite. Due to the abrasive nature of the ground conditions there is expected to be some wear on the cutting equipment on the tunnel boring machines (TBMs) with close monitoring to be carried out to maintain optimal performance.

The new station will connect with a new Transit Priority Corridor (TPC) to provide commuters more accessibility options via bus and active mobility travel. The TPC is expected to be complete in 2029.

Penta Ocean Construction previously worked on the Bright Hill station on the Thomson - East Coast Line (TEL) and is currently building the station, tunnels and customers, immigration and quarantine building for the Johor Bahru - Singapore Rapid Transit System link as well as the tunnel between Suffolk Walk and Novena Rise for the North-South corridor.

CRL1 is Singapore’s eighth metro line and will serve existing and future developments in the eastern, northeastern and western corridors. The 29km line will feature 12 stations, of which more than half will function as interchanges with other lines.
