The provincial transportation minister said yesterday the highway between Bonshaw Bridge and New Haven is paved, and motorists are able to use the road.
The province says the 6.1-kilometre Trans Canada Highway realignment increases safety by improving sight lines, eliminating sharp curves and reducing the overall grade of the highway.
In the fall of 2012 protesters attempted to block the construction project.
Aboriginal groups and environmentalists argued it was resulting in the destruction of forests and infringing on private land.
A number of the protesters were later fined for trespassing.
