Two lanes of eastbound Highway 407 that were shut down following a single-vehicle collision near Thickson Road on Wednesday afternoon have reopened.
Two lanes of the Thickson Road off-ramp, however, remain closed for emergency repairs due to the crash, which sent a man in his 70s to the hospital.

Ornge air ambulance service told CP24 they transported a male to Sunnybrook Health Sciences Centre with critical injuries.
Ontario Provincial Police later said the driver of the vehicle was taken to a Toronto-area trauma centre with non-life-threatening injuries.
Police said the motorist collided with a guardrail and their vehicle flipped over.
