Highway 28 is closed in both directions between Highway 118 at Paudash and Jeff Road, around 7 kilometres north of Apsley, due to a serious collision.
At around 3:15 p.m. on Sunday afternoon (September 20), a motorcycle was travelling southbound on Highway 28 north of Jeff Road when the driver lost control for an unknown reason.
One male victim has been transported by air ambulance to a Toronto-area hospital with life-threatening injuries.
Southbound traffic is being detoured at Highway 118 in Paudash and northbound traffic is being detoured at Jeff Road.
Drivers should give themselves extra time if travelling in this area due to the length of the detour. The closure will remain in place for several hours while police investigate.
