The Wellington Urban Motorway, part of State HIghway 1, is the main road into and out of Wellington, New Zealand. It is 7 km long, ranges from three to seven lanes wide, and extends from the base of the Ngauranga Gorge into the Wellington CBD.
From the Ngauranga Interchange (State Highways 1 & 2), the motorway travels south across reclaimed land alongside the Wairarapa and North Island Main Trunk railway lines. After passing through the suburb of Kaiwharawhara, the motorway travels across the 1335m long Thorndon overbridges, the longest bridges in the North Island, before entering the suburb of Thorndon. Shortly after, it enters the Terrace Tunnel before terminating at Vivian Street in Wellington City.
