State Highway 76 (New Zealand)
State Highway 76 (SH 76) is a 22.6 km state highway in Christchurch, New Zealand. It was officially designated in 2012 after stage 1 of the Christchurch Southern Motorway opened. Much of SH 76 was previously part of SH 73 and includes the former two-lane Christchurch Arterial Motorway, which was upgraded to four lanes. SH 76 makes up most of the Christchurch Southern Motorway and provides the quickest route from the south of Christchurch to the city centre and to Lyttelton.
Stage 2 of the Christchurch Southern Motorway began in October 2016, extending SH 76 to terminate at SH 1 near Robinsons Road. In February 2025, the government announced that the Brougham Street section would be upgraded as a Road of Regional Significance, with a planned NZ$100–150 million investment, including an overbridge between Collins and Simeon Streets. In April 2025, the section from Curletts Road to SH 1 (and the continuation of the Southern Motorway on SH 1 to Weedons Road) was made the first 110 km/h road in the South Island.
SH 76 begins at a grade-separated intersection with SH 74 near the Lyttelton road tunnel and runs east to west through suburban Christchurch along Port Hills Road, Opawa Road and Brougham Street (this portion used to be SH 73). At the western end of Brougham Street, the Christchurch Southern Motorway begins. The Curletts Road interchange is a key junction where SH 75 to Akaroa via Banks Peninsula and SH 73 to the West Coast via Arthur’s Pass start. The motorway continues west for about 7.5 km, passes Halswell Junction Road and Shands Road interchanges, and ends at SH 1 just north of Rolleston.
