INTERSECTION works are now under way in the southbound lanes of the Calder Highway in Carwarp.
Works to increase turning space for large vehicles began today, and will be carried out until the end of June.
Minor delays are expected.
Traffic controllers will be in place to assist traffic travelling through the area. Speeds will also be reduced to 40km/h during construction for the safety of road workers and drivers.
The speed limit will be returned to 80km/h outside of work hours.
