Authorities have announced the complete closure of the Biff Tunnel from Friday 1 August 2025, starting at 9pm, until Monday 4 August until 5am. The reason is to replace the lighting system. The date was chosen in anticipation of the traditional collective holiday to minimise the impact on traffic.
After a complete traffic shutdown, the repair work will continue at night: Monday to Friday, every night from 21:00 to 5:00, until 29 August. These measures have been thoughtfully postponed until after the school holidays to reduce discomfort for most drivers.
A diversion via the Biff roundabout will be organised for the duration of the works. Up-to-date information about the closures can be found on the CITA Traffic Control and Information Service website.
