A two-vehicle crash left two people seriously injured after their cars collided head on on Highway 101 near New Minas, N.S., RCMP said Friday. 

A LifeFlight helicopter flew a 42-year-old Wolfville woman to hospital with life-threatening injuries. On Saturday, an RCMP spokesperson said the woman is expected to survive her injuries.

 An ambulance took a 46-year-old Coldbrook man to hospital for serious injuries. 

The crash happened around 7:44 a.m. between Exit 12 and Exit 13 near New Minas.

The RCMP had closed the highway between those two exits while they investigated, but it reopened mid-afternoon. 

It's not clear what caused the crash. Police said the weather was bad. A traffic reconstructionist is examining the scene.
