The Sentosa Gateway Tunnel has been opened to traffic on 27 April 2017. It is a one-way tunnel that connects outbound traffic from Sentosa Island directly to Keppel Road and Lower Delta Road.
The Tunnel will help to alleviate the current congestion experienced at the busy at-grade junctions at Sentosa Gateway, Telok Blangah Road, Kampong Bahru Road and Lower Delta Road.
As the SGT is in close proximity to the North East Line MRT tunnels and the West Coast Highway viaduct foundations, it was constructed with a limited headroom of 3.5m. In view of the height constraints, only cars and motorcycles will be permitted to use the tunnel.
Buses, heavy and light goods vehicles such as pickups, vans and lorries etc. can continue using the at-grade roads towards Telok Blangah Road to reach their destinations.
Motorists are advised to plan their routes in advance and follow the traffic signs within and outside of the tunnel to help with navigation and road connections.
