Singapore’s Changi Southern Corridor: LTA Awards Major Road Improvement Contract for Terminal 5

The Land Transport Authority (LTA) of Singapore has officially awarded a civil contract valued at approximately S$757 million to a joint venture between CES_SDC and KTC Civil Engineering and Construction. This development marks a significant milestone in the infrastructure expansion supporting the future Changi Airport Terminal 5 (T5).

Strategic Connectivity for Changi East

The project is a core component of the Changi Southern Corridor, a broader initiative designed to bolster infrastructure in the Changi East region. By enhancing the road network, the LTA aims to provide full and direct connectivity to the future terminal from key arterial routes, including the East Coast Parkway (ECP), the Pan Island Expressway (PIE), and Xilin Avenue.

According to the LTA, the scope of work for the joint venture includes:

• Design and construction: Development of new flyovers, tunnels, and underpasses to streamline traffic flow.
• Canal expansion: Widening of the existing Changi Airport Diversion Canal to accommodate the new infrastructure.
• Road network enhancements: Targeted improvements along Xilin Avenue, the ECP, Tanah Merah Coast Road, and Changi Coast Walk.

Timeline and Long-Term Impact

Construction activities for these road enhancements are scheduled to commence in the third quarter of 2026. Once completed, the project is expected to offer motorists smoother traffic flow and increased travel options when accessing the Changi East region from the PIE and ECP. The plan incorporates the addition of new cycling paths, which are slated for completion by 2034.

This award represents the latest effort by the LTA to prepare the transport network for the high-capacity needs of T5. The authority has indicated that further tenders for additional road and cycling path works are currently planned for the fourth quarter of 2026, signaling a sustained period of infrastructure development in the area.
