State Highway 86 (SH 86) is a New Zealand state highway connecting the city of Dunedin's airport to and the city itself. It was gazetted in 2003.[1] It is a two-lane single carriageway.
The road begins at an intersection with SH 1 in the satellite town of Allanton and proceeds in a north-northwesterly direction over the Taieri Plains. After about 1.5 km the road curves to the west-southwest and proceeds for about 3.5 km before veering to the NNW and then to the SSW again at Momona before terminating at Dunedin airport.
