The number brings to 45 the number of wayward drivers caught in just 36 hours since the final piece of the $404 million freeway was opened to vehicles on Monday morning.

“It is pretty bad to get 30 in one day,” Leading Senior Constable Kevyn Hume-Cook of the traffic management unit said.

Two officers spent just five hours on the freeway yesterday - netting an offender every 10 minutes.

The highest motorist was caught travelling at 112kmh - more than 30kmh above the speed limit.

Leading Senior Constable Hume-Cook said the probationary Blackburn man was fined $301 and lost his licence for one month.

On Monday police picked up 15 people for speeding. Five of those drivers were caught travelling more than 25kmh above the speed limit, and two hit speeds more than 130kmh.

The first impound of the new freeway - a 34-year-old Bendigo man - was clocked at 112kmh on Monday.

Leading Senior Constable Hume-Cook said the man was a disqualified driver, and held a prior conviction for driving while disqualified.

He was also alcohol affected, but refused to accompany police back to the station for a breath test.

Leading Senior Constable Hume-Cook admitted police were ready when the road opened.

“The 80kmh speed zone is there for a reason,” he said.

“Considering the number of cars using the new road . . . it’s actually a very small percentage that are doing the wrong thing.”

However, he warned that police would continue targeting the area.

VicRoads says the speed limit on the new section is expected to be raised to 110kmh later this week.
