One lane is now open on N.W.T.'s Highway 3, after it was closed earlier Tuesday between Behchoko and Fort Providence after a fuel truck jackknifed near Chan Lake.
Vehicles will be allowed to go through the collision scene with an escort from the Department of Transportation. The department said motorists should expect delays.
The driver, who is from Edmonton, was able to walk away from the scene but was then taken to the hospital with non-life-threatening injuries. He is being treated at the Stanton Territorial Hospital in Yellowknife.
The semi-trailer was hauling 53,000 litres of fuel, but it's unclear what type of fuel it was. Some fuel is leaking from one container of the truck.
"It is all in a ditch," said Earl Blacklock, spokesperson for the Department of Transportation. "It is not threatening any waterways and we expect that it will be able to be cleaned up fairly readily."
He said the partial closure could last until this evening or even longer depending on how the investigation goes, once the spill is cleaned up.
"All we know is it was a single vehicle collision on a stretch of highway that was in daylight hours and the highway was dry. There is no obvious cause for the collision," said Blacklock.
Peter Menacho saw the wreck up close as he was driving from Fort Providence to Yellowknife. He was concerned for the driver.
"He was laying down on a mattress I think. And he was assisted by one lady until the ambulance came. We offered our help and we wanted to give him some water, but he said he was fine," said Menacho.
The RCMP is investigating, but has yet to comment on the collision.
Truck helping with cleanup also rolls over
This afternoon, a piece of heavy equipment involved in cleaning up fuel from the accident also rolled over.
"The equipment operator sustained non-life threatening injuries and was transported to the hospital," said Blacklock.
He said the cleanup was being done by a private company, but would not say which company. Blacklock said the equipment was operating on the angled side of the ditch when it rolled.
