The Dettah ice road has closed for the season.
In a tweet Monday night, the territorial Department of Transportation said the road would no longer stay open due to ‘extremely warm weather.’
That means no further travel is permitted on the road linking Yellowknife and Dettah across the frozen Great Slave Lake.
This year’s closure comes seven days later than last year’s announcement. Following a mild start to winter, the road opened on January 2 this year.
The 15-year average opening date for the Dettah ice road is December 21, with an average closing date of April 21.
On Monday afternoon, the department warned the route could close on short notice. That decision became official later in the evening, with the route closing to all traffic at 10:00pm.
Separately, government officials say ice roads in Aklavik and Tuktoyaktuk could close with little or no notice due to deteriorating conditions.
