The break has proven difficult and has taken crews longer to fix with road closures still in place during peak hour times this afternoon.
Due to the location of the break along Creekside Boulevard, parts of the southbound lane between Lomandra Drive and Brushwood Street will remain closed while urgent repairs are completed.
Unitywater Executive Manager Customer Delivery Rhett Duncan asked motorists to avoid the area if possible.
“If you need to travel between Kawana and Caloundra, we suggest you use the Nicklin Way via Kawana Way,” he said.
“We have worked continuously overnight and throughout the day to repair the broken pipe and are treating this with the highest priority.
“We apologise for the inconvenience and thank the public for their patience as we resolve this.”
