A collision shut down a stretch of highway near the Manitoba-Ontario border Sunday.

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.
