The road was closed for more than an hour, although one lane was opened for short periods to clear the backlog of vehicles.
Emergency services from Kaitaia and Doubtless Bay responded to the crash, firefighters and St John crews working for some time to extricate the injured woman from the wreckage of the car. The rescue helicopter arrived before she had been freed, landing in a paddock across the road.
The crash prompted an undertaking from Kaitaia's Chief Fire Officer (and Far North District councillor) Colin Kitchen to promote the painting of arrows in the left-hand lanes of important tourist routes.
We're getting too many of these crashes, and they almost always seem to involve visitors who are used to driving on the right," he said.
"This [Inland] road leads to a major tourist destination, and is a prime example of where arrows are needed."
Mr Kitchen stood to be corrected but believed that arrows had been painted immediately north of the bridge, but had been obliterated when the road was re-sealed. Whatever the case, he would be calling for arrows to be painted now.
State Highway 10 at both ends of the single-lane bridge at Taipa and Kerikeri's Wairoa Road were two more that should have arrows for the benefit of tourists, he added.
