The N.W.T.'s winter road to the diamond mines is expected to open today, which means motorists can expect heavy truck traffic north and southbound on the Ingraham Trail east of Yellowknife until the end of March.
Slow ice formation and heavy snow delayed the opening by more than a week.
The Department of Transportation is asking vehicles not to park or stop on the ice road during this time.
It's preparing for one of the busiest years on record, with more than 8,000 loads of freight.
The Tibbitt to Contwoyto winter road is a joint venture run by owners of the territory's diamond mines.
