Highway 527 north of Thunder Bay was fully open to traffic on Sunday afternoon.

The roadway was closed as of Wednesday morning because of a washout.

The Ministry of Transportation said in a news release that crews continue to work at the site, and ask drivers to obey speed limits and flag persons.

One man, a Canada Post driver, was killed when the vehicle he was driving went into the washout, and burst into flames.

State of emergency

Gull Bay First Nation declared a state of emergency on Saturday, after access to the community was limited because of the washout. The state of emergency has since been lifted, as road access was restored.

Chief Wilfred King said people in his community were frustrated by a lack of information.

"We weren't given any kind of affirmative answers on when the road would be re-opened" he said.

King said he was originally told the road would reopen on Friday.
