Stabilizing a Landslide-Prone Highway

Since it was built in 1984, active landslides have plagued Highway 744 that rests above the town of Peace River, about 500 km northwest of Edmonton. The two-lane highway runs along the sloping face of a narrow ridge that separates the Peace River and Heart River valleys. Keeping this road open has been a serious challenge requiring a lot of heavy equipment.
A recent landslide was first seen to impact a 120 m section of Highway 744 when maintenance workers noticed transverse diagonal cracks in the asphalt. Both lanes of the highway continued to rapidly deteriorate and Alberta Transportation closed the road due to safety concerns. Within a few days, large sections of the highway had completely collapsed due to the shifting earth underneath the roadbed. Even though this is a relatively remote area, Highway 744 acts as a vital lifeline to the town of Peace River for the thousand cars that pass along it per day.  Alberta Transportation decided that permanently closing the highway or building an alternate highway outside the landslide area weren’t viable options.
As a long-term solution, tie-back retaining walls were selected to stabilize the landslide mass and anchor the remaining strata.  Two tie-back walls were constructed about 300 metres apart just below the damaged sections of the highway. Both walls were installed by Doublestar Drilling using Soilmec SM-14, SM-20 and SR-30 rigs.
