Providing Direct Connections to Keppel Road & Lower Delta Road
The Sentosa Gateway Tunnel will open on 27 April 2017 (Thursday) at 10am.
2. The Sentosa Gateway Tunnel, is a one-way road tunnel that connects outbound traffic from Sentosa Island directly to Lower Delta Road and Keppel Road. It will help alleviate the current congestion experienced at the busy at-grade traffic junctions at Sentosa Gateway, Telok Blangah Road, Kampong Bahru Road and Lower Delta Road, especially during evening peak hours and the weekends. Please refer to Annex for a detailed map.
3. As the Sentosa Gateway Tunnel had to be constructed close to the North East Line MRT tunnels and the West Coast Highway viaduct foundations, it was designed with a height constraint of 3.5m. In view of the height constraint, and for fire safety reasons, only cars and motorcycles are permitted to use the Sentosa Gateway Tunnel. Buses and goods vehicles can continue using the existing at-grade roads towards Telok Blangah Road to reach their destinations.
4. Warning signs and height restriction beams will be installed to prevent buses and goods vehicles from entering the Sentosa Gateway Tunnel. LTA will carry out a series of engagement activities including briefings and sending direct mailers to stakeholders in the coming weeks.
5. Motorists are advised to plan their routes in advance and follow the traffic signs within and outside of the tunnel to help them navigate to their destinations.
