Huron OPP say two young women were seriously injured after they fell from the Menesetung Bridge near North Harbour Road in Goderich Tuesday afternoon.
OPP, fire, paramedics and Coast Guard personnel were called to the Maitland River around 12:30 p.m.
Two witnesses entered the river and provided lifesaving help to the women until rescue units could arrive, police say.
An air ambulance transported the women to hospital. A 17-year-old from Bluewater has serious, but non-life threatening injuries and is in a London hospital, while a 20-year-old Goderich woman was taken to a local hospital with serious injuries.
Police say there are no safety issues with the bridge, which remains open to the public.
The investigation continues.
