Emergency Services for Expressways and Tunnels


If there is an incident on expressways or inside tunnels, the EMAS vehicle recovery crew is activated to ensure that the incident site is safe, and to tow away any stalled vehicles.

LTA traffic marshals control traffic and perform on-scene management duties such as preserving evidence for accidents involving slight injuries. They work together with the EMAS recovery crew, as well as the Traffic Police and Singapore Civil Defence Force to bring traffic back to normal as quickly as possible.

Safety features in Tunnels


Our road tunnels are monitored round the clock by LTA’s Operations Control Centre. When an incident occurs, our emergency protocol will be activated to manage the incident.

In the event of a fire, the tunnel ventilation system will remove smoke. The MCE, Woodsville Tunnel and Sentosa Gateway Tunnel are also equipped with an overhead water sprinkler system to help fight fires.

To facilitate evacuation on foot, there are emergency escape staircases and cross passage doors located in longer tunnels such as the CTE, KPE and MCE.

Fire service cabinets are located every 50m in tunnels, next to the left-most lane. Emergency SOS phones are found every 100m, in alternate fire service cabinets.

Emergency exits in tunnels

If you have to evacuate any of the tunnels on foot, head for the nearest exit:

  • For Woodsville Tunnel and Fort Canning Tunnel, head for the tunnel’s entrance, away from the incident or smoke.
  • For CTE, KPE, MCE tunnels and Sentosa Gateway Tunnel, head for the emergency escape staircase, located every 500m in the tunnel next to the left-most lane. The stairs lead to the street level.
  • For CTE, KPE and MCE tunnels, you can also head for the pedestrian cross passage door, located every 100m next to the right-most lane. The doors lead to the tunnel in the opposite-direction.
