Construction Update – August 2024
Construction on the Highway 97 at Cottonwood Hill Project is underway. Drivers will see work on 1.4 km of Highway 97, including realignment of approximately 500 metres of road through the slide area and removal of weight from the top of the slide to improve safety and road stability. During construction, single-lane traffic will be implemented in both directions at times, and later this summer there may be single-lane alternating traffic with stoppages of up to 20 minutes.
In addition, tree clearing work is underway in Dragon Lake Quarry, which is expected to take approximately a month.
Please drive with caution through the construction zone.
