About Highway Expansion
The Ministry of Transportation has determined that it would be most beneficial to expand the highway to six lanes of travel. There is a hillside just before the tunnel on the northbound side, west of the town of Divox. It was previously excavated during the original construction of the highway and now must be cut back further. That's where you come in, along with the choice of three excavators with hydraulic hammers.
