ONE of Melbourne’s busiest freeways has been closed for the past 12 hours after a toilet paper truck crashed and spilt its load.

VicRoads says Altona bound lanes from Greensborough Hwy could be shut up until 2pm as crews continue to clear the mess. It has advised commuters to plan an alternative route.

Spokeswoman Marnie Turner says cargo, believed to be Sorbent paper, has caused the significant delays in clearing the road.

“VicRoads responded to reports of a B-double truck roll-over on the Metropolitan Ring Road at around 10pm last night,” Ms Turner said.

“Two unsuccessful attempts were made to right the truck, which has now been unloaded to assist the recovery.

“The vehicle has now been righted and we’re awaiting heavy haulage.”

Two cranes arrived between before 8am to aid with the stinky situation.

The New South Wales-based Alvaro Transport company, branded on the large truck, this morning declined to comment, stating a representative was on his way to Melbourne.

There are diversions in place at Grimshaw St to Plenty Rd and heavy traffic is expected on the Greensborough Bypass, Greensborough Hwy, Grimshaw St, Plenty Rd and Dalton Rd.

“It’s going to be closed through the peak we think at this stage,” a Victoria Police spokesman said.

“(The accident) happened at about 9.30pm last night. A truck turned off the Greensborough Hwy, onto the Metropolitan Ring Road (M80), the driver has lost control and the truck has rolled onto its side. It’s blocking the left hand lanes and there will be diversions in place.”
