The trouble spots in question are the main entrance to Caroline Springs from the Deer Park bypass, Christies Road, and the intersection of Ferris Road and the Western Freeway off-ramp at Melton.

Cr Sophie Ramsey said the Ferris Road intersection was in urgent need of an upgrade and VicRoads needed to come up with the money to improve traffic flow. Traffic lights have been suggested as one option.

Afternoon peak-hour traffic is also backing up on Christies Road as residents exit the Deer Park bypass to get to their homes at Caroline Springs.

CEO Neville Smith said council was "acutely aware" of the problems at both locations and would write to VicRoads, as it had in the past. The problem was getting VicRoads to see the urgency of improving traffic flow and providing infrastructure that met demand, he said.

VicRoads regional director for the metropolitan north-west region Nial Finegan said: "VicRoads looks forward to receiving council's letter [on Ferris Road] and working with them in the future.We will continue to work alongside council to review these and other competing statewide priorities."
