Canterbury

Christchurch Northern Motorway (SH 1)

From north of Kaiapoi over the Waimakariri River through to the northern suburb of Belfast.
Its southernmost interchange (Kainga/Marshland) is unusual in that northbound traffic merges from the right, while southbound traffic is carried on a large loop to the right up and over the onramp. The reason for this design was to accommodate a future southern extension into central Christchurch, with the northbound onramp being the first part of the northbound carriageway. Northbound there are three more interchanges; Tram Road (Oxford), north off, south on; Kaiapoi (diamond interchange); and Lineside Road ( to Rangiora), north off, south on.
