Loose loads causing chaos and destruction on Melbourne freeways

Bicycles, bricks and even dollhouses are just some of the unsecured items that have come flying off vehicles and onto Melbourne freeways in recent weeks.

Authorities are now warning motorists of the dangers and risks surrounding unsecured loads.

CityLink General Manger for Victorian Operations Philip Naulls said unsecured loads were a "massive" issue.

He said it was a "surprisingly large issue".

"The key message to motorists is that we want you to travel through our city but please secure your loads," he said.

"Before you travel please check your load, check your straps and enjoy your journey."

Mr Naulls said since the beginning of the year, CityLink had dealt with 600 loss of load incidents.

"We are only in May," he said.

"Each of those individual events creates a hazard. We are clearing those events quickly but there still is a delay to those motorists.

"It creates an immediate hazard to the motorists around you."

A similar statement was shared by EastLink corporate affairs manager Doug Spencer-Roy.

He said last month alone, there were 120 separate incidents.

"That's 120 times where we had to send out a team and clear out debris off the road," he said.

"It's a high number and that's 120 potential accidents... we take it all very seriously."

Mr Spencer-Roy said unsecured loads puts every motorist at risk.

"We see items taken by the wind or (in some situations) a series of items might fall of a truck and that can cause widespread damage if it collided with multiple vehicles," he said.

"It's careless and every item should be secured."
