Motorists warned of detours after serious crash on the Riddoch Highway at Nangwarry

A woman has died and another is in critical condition following a serious crash on the Riddoch Highway.

A woman has died and another is fighting for life after a serious crash at Nangwarry.

Just after 10.30am on Saturday, emergency services workers attended the scene of a serious two car collision on the Riddoch Highway involving a Ford station wagon and Toyota utility.

The driver of the Ford, a 59-year-old Nangwarry woman, died at the scene while her passenger, a 68-year-old Mount Gambier woman, was taken to hospital with critical injuries.

The driver of the Toyota, a 60-year-old man and his passenger, a 23-year-old man both of Mingbool were not injured.

The 59-year-old Nangwarry woman is the 87th life lost on South Australian roads this year.

Motorists are urged to avoid travelling on the Riddoch Highway between Penola and Nangwarry due to road detours which will remain in place for several hours during Major Crash investigations occur.

It comes two months after a horror multi-car crash near the same spot that killed two children.

The two Eykelenburg children were travelling with their family in a grey Toyota station wagon that had braked to avoid hitting a black Holden sedan, which struck an emu.

The Toyota was then struck from behind by a white Nissan ute.
