Changi Southern Corridor

Slated for completion in 2034, the Changi Southern Corridor will support the future Changi Airport Terminal 5 (T5) and developments at Changi East. Works will include the reconfiguration of the existing Changi Flyover and Tanah Merah Flyover, and road enhancements to Pan Island Expressway (PIE), East Coast Parkway (ECP), Tanah Merah Coast Road (TMCR) and Xilin Avenue.

These road improvements will:

Enhance the multi-modal connectivity of the Changi region;
Support the growth and development of Changi’s aviation sector; and
Improve access to and from Changi Airport to ECP and PIE/TPE, and between TMCR and PIE through ECP/PIE and will complement the Changi Northern Corridor in providing motorists with an alternative travel route to the region.

Cyclists will also enjoy 3.5km of new cycling paths along Xilin Avenue and Tanah Merah Coast Road, in tandem with the enhancements to the road network. These cycling paths will complement the existing Park Connector Network and on-road cycling lanes to connect Tampines and East Coast to T5. Pedestrians, cyclists and other active mobility users can enjoy safer and more comfortable journeys.

Proposed Enhancement of Pan Island Expressway (PIE) and East Coast Parkway (ECP) between Upper Changi Flyover and Tanah Merah Flyover (Contract DE151)

Proposed Enhancement of Pan Island Expressway (PIE) and East Coast Parkway (ECP) between Upper Changi Flyover and Tanah Merah Flyover (Contract DE151)

1. This project comprises the enhancement of the existing interchange at PIE/ECP/Airport Boulevard with a new vehicular underpass and flyover, widening of the stretch of PIE between Upper Changi Flyover and Changi Flyover and the construction of a new road parallel to ECP between Changi Flyover and Tanah Merah Flyover.

2. To facilitate these works, traffic diversion on PIE and ECP will be necessary due to site constraints. LTA will take measures to mitigate inconvenience to motorists and minimise impact to greenery during construction works.

3. When completed, motorists can expect smoother traffic flow to and from Changi Airport to ECP and PIE/TPE, and between Tanah Merah Coast Road and PIE.
