Dunedin-Waitati Highway (SH 1), formerly (and currently in official land-use planning contexts) called Dunedin Northern Motorway, is a two to four-lane limited-access road which provides the main route north from the city of Dunedin, New Zealand. It was constructed in the 1950s[when?] to replace narrow, winding routes via Port Chalmers and Mount Cargill. The road is occasionally briefly closed by snowfall in winter. Dunedin-Waitati Hwy is relatively steep and winding, traversing part of the Silverpeaks range of hills. It begins a short distance north-west from where the two main parts of Dunedin's central business district one-way street system recombine near The Gardens Corner with a pair of bridges over the Water of Leith. The highway connects with Bank St and George St then climbs Pine Hill Rd to the northern Dunedin suburb of Pine Hill. From there itfollows the northeastern side of the Leith Valley, then crosses the headwaters of the Leith before traversing the Leith Saddle and taking a roller-coaster-like course to the valley of the Waitati River, then to Waitati.
