A 24-year-old woman was sent to hospital after a three-vehicle crash in Halton Hills on Tuesday morning.
Halton Police say the driver sustained serious injuries after her Mazda 3 sedan collided with a dump truck and a transport trailer around 9 a.m. at the intersection of Trafalgar Road and Hornby Road in Milton.
Investigators say the woman was transported to Sunnybrook Hospital for emergency treatment.
Two other drivers were involved, a 46-year-old from Cambridge and a 61-year-old Brampton resident operating a transport truck and trailer.
The intersection was reported by police as an active construction zone at the time of the collision.
Trafalgar Road was closed for close to six hours for an investigation.
Police say that probe is still ongoing and no charges have been laid at this time.
