Highway 400 was closed in both directions this morning after a truck struck and damaged the guardrail between Innisfil Beach Road and Mapleview Drive.
The clean-up continues at the scene.
The northbound lanes are expected to open before southbound lanes, but no timeline has been given.
Crews are working to remove a transport truck from down a southbound embankment. A new guardrail also has to be installed.
"We have major problems here on the 400," said Sgt. Kerry Schmidt of the OPP’s Highway Safety Division.
A northbound truck lost control in the snow and slush, according to OPP.
“The truck jack-knifed as it went through the centre guardrail,” Schmidt said.
The destroyed rail then flung out into the southbound lanes, he added. The rail struck a southbound truck, with a load of vinegar, causing damage to its front end and wheels. It came to a rest down a southbound embankment.
“It went in there pretty quick, but it did stay upright,” Schmidt said. “The front of the trailer is ripped wide open.”
A concrete wall was being brought to the scene to replace the damaged metal guardrail.
Heavy equipment is on the scene to remove the southbound truck from down an embankment.
“They’ve still got a lot of work to do here,” Schmidt said shortly before noon.
No injuries have been reported.
The northbound truck was being inspected on the side of the highway.
The driver of the northbound transport truck has been charged with careless driving.
