Work is under way on Mooney Mooney Creek Bridge which impacts heavy vehicles between the Calga and Somersby interchanges. Visit the Mooney Mooney Creek Bridge web page for detour details.

Changed traffic conditions

Changed traffic conditions are now in place to allow work to start on building the third northbound lane.

There is no change to the existing two southbound travel lanes during this time. Speed limits will remain at 80km/h for the safety of workers and all road users
