Wellington's Basin Reserve currently functions as a large roundabout with signals. Congestion is affecting SH1 traffic, local traffic, freight, pedestrians, cyclists and bus travel. Following extensive investigations and community engagement, the bridge option (Option A) has been selected.
The road network around the Basin Reserve is an important link in the Wellington road of national significance (RoNS), the State Highway 1 corridor between Levin and Wellington Airport. The improvements will assist the smooth flow of traffic between the north and south of Wellington City. The improvements are intended to contribute to providing a high-quality, high-capacity, fast and reliable passenger transport spine as part of the Wellington Northern CorridorRoNS from Levin to Wellington Airport. This will improve the reliability and travel times of the route for through traffic, particularly to Wellington Airport and Wellington Hospital.
This work is part of the Tunnel to Tunnel (T2T) suite of inner city transport improvements.
