Police are investigating a two-vehicle crash in Gundagai this afternoon.

About 2.40pm (Sunday 15 November 2015), emergency services were called to The Hume Highway near the ‘Dog on the Tucker Box’, following reports of a crash.

Initial investigations suggest a Ford Falcon sedan was travelling north on the Hume Highway when it crashed into a Mitsubishi sedan turning onto the highway from a service station.

The driver of the Mitsubishi, a woman believed to be aged in her late teens or early 20s, was airlifted to hospital in a critical condition.

The driver and passenger of the Ford, a man and woman, were treated at the scene by Ambulance Paramedics, before being taken to Wagga Wagga Base Hospital with serious injuries.

A crime scene has been established by officers from Cootamundra Local Area Command and investigations are continuing.

The Hume Highway is partially closed in both directions as investigations take place.
