TRAFFIC has flowed uninterrupted along the Western Highway near Stawell, despite a clean-up operation to clear a four-kilometre diesel leakage.
Stawell Sergeant Pat Harrington said an 18-wheel semi-trailer's fuel tank split while travelling east along the highway at 2.50pm, towards Stawell.
He said the driver passed through Deep Lead, en route to Melbourne, before he was advised his truck was leaking.
"Someone must have spotted it and rang through," Sgt Harrington said.
The driver pulled into a carpark west of Stawell as soon as he realised what was happening.
"The Country Fire Authority was on the scene pretty quick, and took charge of the scene," Sgt Harrington said.
He said police, CFA, Northern Grampians Shire Council and VicRoads workers attended to help stop the flow of fuel and spread some sand on the road to soak up the spilled diesel.
Sgt Harrington said the clean-up took place without the need for any road closures or disruptions to the traffic.
"It was a very good effort from the CFA, VicRoads, the local shire and police,'' he said.
Sgt Harrington also praised the person who alerted the driver to the leak.
He encouraged people to follow suit and report spills to police.
