DETECTIVES from the Major Collision Investigation Unit are still at the scene of a fatal collision that occurred in Dixons Creek last night (Sunday).
It is believed a semi-trailer jack-knifed on the Melba Highway, which caused it to collide with two other vehicles heading in the opposite direction about 8.20pm.
A Dandenong woman aged in her fifties, the sole occupant of a Mitsubishi van, died at the scene.
A 29-year-old female driver from Pakenham Upper and her passenger, a 21-year-old Berwick woman, were in a Nissan Navara towing a horse float.
They were both taken to the Royal Melbourne Hospital with non-life threatening injuries.
One horse died at the scene and the other was put down by a local ranger.
The truck driver, a 41-year-old Swan Hill man, was taken to The Alfred hospital in a serious condition.
The section of Melba Highway between Healesville-Kinglake Road and Old Healesville Road is expected to be blocked until further notice.
Anyone who may have witnessed the collision is asked to contact Crime Stoppers on 1800 333 000 or www.crimestoppers.com.au
