The entire Central Expressway (CTE) tunnels will be temporarily closed to traffic in both directions on Sunday, 14 June 2009, from 12.00am to 6.00am. This is to facilitate an emergency exercise to be jointly conducted by the Singapore Civil Defence Force (SCDF) and the Land Transport Authority (LTA) during these hours.

This joint exercise is part of an ongoing effort by the SCDF and the LTA to sharpen and enhance the operational readiness of its emergency responders, and the coordination between the two agencies in dealing with emergencies in the CTE tunnels.

Motorists are advised to use the following alternative routes:

Towards the Ayer Rajah Expressway (AYE)

Towards the Seletar Expressway (SLE)

Motorists are therefore advised to avoid the above roads and are reminded not to stop or park their vehicle illegally. Traffic Police will take strict enforcement action, including the towing away of illegally parked vehicles.

Motorists are encouraged to use the proposed alternative routes and plan their journeys carefully to minimise inconvenience. We seek the public"s co-operation and advise all motorists to follow directional signs displayed and the directions of the officers on duty.
