The Land Transport Authority (LTA) has awarded the second civil contract for the enhancement of road networks along Xilin Avenue, East Coast Parkway (ECP) and Tanah Merah Coast Road (TMCR), as part of the Changi Southern Corridor project, to a joint venture between CES_SDC Pte Ltd and KTC Civil Engineering & Construction Pte Ltd. Construction is expected to commence in the third quarter of 2026.
Valued at around S$757 million, the contract covers the design and construction of new flyovers, tunnels and underpasses, as well as the widening of the existing Changi Airport Diversion Canal with new vehicular bridges and road improvement works along Xilin Avenue, ECP, TMCR and Changi Coast Walk. When completed, the enhancements will provide full and direct road connectivity to the future Changi Airport Terminal 5 (T5) from ECP, PIE and Xilin Avenue.
Apart from road infrastructure, new cycling paths will be built along Xilin Avenue and TMCR to boost connectivity between Tampines, East Coast and the future Changi East developments. In addition, the existing pedestrian underpass (ECP Underpass No. 10) between ECP and the ECP Service Road will be upgraded and extended to serve both pedestrians and cyclists. Together with the existing Park Connector Network, these improvements will strengthen first- and last-mile connectivity and offer more seamless, barrier-free journeys along the Xilin–Changi East corridor.
To facilitate these works, traffic diversion along the ECP, PIE and TMCR will be necessary due to site constraints and the construction sequencing required for the infrastructure works, said LTA. More details will be announced at a later date.
CES_SDC (formerly known as Sembcorp Design and Construction Pte Ltd) was involved in the construction of Marina South station on the Thomson-East Coast Line, and is currently working on the construction of two stations on the Jurong Region Line, as well as another station along the Cross Island Line-Punggol Extension.
KTC Civil Engineering & Construction previously constructed Tampines interchange station on the Downtown Line and Orchard Boulevard station on the Thomson-East Coast Line. The contractor is currently involved in the construction of Sungei Bedok station on the Thomson-East Coast Line and two stations on the Cross Island Line.
The first contract of the Changi Southern Corridor project was awarded in September 2024 and comprised enhancements to the existing interchange at PIE/ECP/Airport Boulevard. Works under this contract commenced in the fourth quarter of 2024.
After the second contract, LTA plans to call the remaining road civil infrastructure tender in the fourth quarter of 2026. The scope will include enhancements to the road infrastructure networks fronting the entrance to the future Changi Airport T5 along TMCR, together with the construction and realignment of cycling paths and park connectors along TMCR. When completed, there will be 3.5 km of new cycling paths, providing pedestrians, cyclists and other active mobility users with safer and more comfortable journeys.
