The Provincial Government has announced plans to twin an additional 240 kilometres of Highway 63 between Fort McMurray and the junction of Highway 55 near Grassland.
Tree clearing and grading work is scheduled to begin this fall.
The first phase of construction includes 36 kilometres of tree clearing and 16.8 kilometres of grading within that stretch, at a cost of $19 million.
The total cost of the twinning is approximately $1 billion.
As well, the second phase of the Thickwood Boulevard and Confederation Way interchanges will begin later this fall.
