Night work on the motorway next week involves drainage installation, sheet piling work, and general road maintenance. If it rains or ground conditions are too wet, work will be postponed until the next available dry night.

Work during the night will allow our crews to operate equipment safely while adjacent to the existing traffic lanes. Work in the shoulder and median work zones will continue during the daytime next week, but this will not affect traffic movements.

Night closures are typically from 9pm at night to 5am in the morning. Detours will be in place to take motorists along local roads, leading back to the next motorway interchange. All detours will be clearly signposted, and maps of the typical routes can be found on our website.  Please allow extra time for your journey at night.

It is important that motorists keep to the 80 km/h speed limit past our work areas. There will be ongoing truck and project vehicle movements accessing the shoulder and median work sites. Keeping both motorists and our team members safe as possible is imperative and we need everyone's help to do this.

As always, we will be doing our best to minimise effects of these works on motorists as much as we can.

We thank you for your patience as we work to improve journey reliability and safety along the Southern Corridor.
