Frenchman River landslides

Saskatchewan Highways and Transportation (SHT), now the Ministry of Highways and Infrastructure undertook a landslide risk management system program to monitor risk sites, apply technological innovations to prevent any further erosion of the riverbank and plan responses to future landslide movement detected by monitors. Highway 37 south of Shaunavon along the Frenchman River has experienced landslides.
