Around 1 p.m. the province said Highway 1 from Falcon Lake to West Hawk Lake was closed.
A witness told CTV News she saw a semi-truck in the ditch.
Several vehicles could be seen backed up along the highway. The province said a detour was in effect.
No word on what caused the crash or whether anyone was injured.
The highway re-opened shortly after midnight.
