Waiau Uwha River Bridge
At Waiau, you will find one of the longer one-lane bridges in New Zealand over the Waiau Uwha River. It has some passing bays on the river bridge, so you can probably get away with a brief photo stop above the river which is a fine example of a South Island braided river. Try to do this section later in the day as the sun is setting.
Beyond Waiau, the road connects with State Highway 7 to Hanmer Springs.
