Emergency crews and tow truck drivers have spent the night trying to free a truck driver who was stuck in his cab for two days.

The driver's tractor-trailer went off the road and down an embankment about 10 kilometres west of the entrance to Manning Park, some time on Feb. 28.

RCMP said the man had been stuck inside the cab since then.

"I've been on highway patrol for nine years, so I've seen many many crashes of this nature," said Cst. James Halliday with Fraser Valley Traffic Services.

"This is the most complex one I've seen where we had to extricate someone."

Const. James Halliday called it one of the most 'complex' extrications he's ever seen. (Kevin MacDonald)

3 teams worked on the extrication

A mobile mechanic was called out to dismantle the truck's transmission, while search and rescue crews worked on cutting out sections of the truck's cab around the driver.

A local towing company brought in trucks to help keep the truck from sliding further down the embankment.

"It's been six hours that everybody's been working on trying to get the driver out," said Jamie Davis, with the Jamie Davis Towing company.

"Everybody's working hard here together … there must be 25 people working to help free the driver."

Halliday said the driver was awake during the whole process.
