# Saskatchewan Highway 37

Highway 37 is a provincial highway in the Canadian province of Saskatchewan. It runs from Montana Secondary Highway 241 at the US border near the Port of Climax north to Highway 32 at Cabri. Highway 37 is about 186 kilometres (116 mi) long.

## Route description

Highway 37 begins at the Port of Climax border crossing and heads north to Highway 32 at Cabri. It passes through the communities of Climax, Shaunavon, and Gull Lake and connects with Highways 18, 722, 13, 631, 1, 322, and 738.

## 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.
