A young woman was injured in a crash after a car hit ice on the Kawatiri-Murchison highway north of Murchison this morning.
She was a passenger in a car heading from Westport to Nelson which came off a bridge after hitting ice and crashed into the side of a bank. Police said two cars were involved.
The injured woman was flown to Nelson Hospital by the Nelson Marlborough Rescue Helicopter.
Murchison Volunteer deputy fire chief Joe McLellan said the female passenger was ''quite badly injured''.
The driver escaped injury.
The section of highway, 15 minutes north of Murchison around Coal Creek, was closed for sometime as emergency services attended the scene.
The fire brigade was at the scene from around 7am until 9am cleaning up the accident - the road was completely closed for a time then becoming one lane and was back to full capacity around 9am.
McLellan said there was no anti-frost spray on the bridge leaving it icy and ''pretty nasty''.
He reminded people to take care on the roads.
''It's just really important his time of year that people drive particularly carefully and to the conditions. I would say the roads are very very icy out here at the moment,'' he said.
Icy roads were especially a problem after having no rain in the area in the last week, and bridges were particularly dangerous as there was a ''refrigeration'' effect with a lot of moisture floating around so people needed to take extra care, he said.
