State Highway 1 (SH 1) is the longest and most significant road in the New Zealand roading network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island.
SH 1 is 2,033 kilometres (1,263 mi) long, 1,081 km (672 mi) in the North Island and 952 km (592 mi) in the South Island. For the majority of its length it is a two-lane single carriageway, with at-grade intersections and property accesses, in both rural and urban areas. These sections have some passing lanes. Around 215 km (134 mi) of SH 1 is of motorway or expressway standard as of February 2017[update]: 191 km (119 mi) in the North Island and 23 km (14 mi) in the South Island. Current road construction will see an extra 102 km (63 mi) in the North Island and 11 km (7 mi) in the South Island upgraded to motorway or expressway standard by 2022.
State Highway 1 has been earmarked for several motorway projects most of which have surfaced from the National governments Roads of National Significance package announced in 2009.
The most controversial project is the Puhoi to Wellsford motorway (Ara Tūhono) . This is also referred to as the "Holiday Highway" as the current SH 1 becomes heavily congested in holiday periods from holidaymakers travelling to and from Auckland in the summer holiday season and public holiday weekends. Construction of the 18.5 km (11.5 mi) Puhoi to Warkworth section began on 8 December 2016 with the official sod-turning. The motorway will run west of the current SH 1 alignment, starting at the end of the existing Auckland Northern Motorway and terminating onto the existing highway at Kaipara Flats Road, north of Warkworth township. The new motorway is expected to open in late 2021. The NZTA released its preferred alignment for the Warkworth to Wellsford section for consultation in February 2017. The motorway will run from the Puhoi to Warkworth section west of Warkworth northward, passing east of Wellsford and Te Hana to terminate onto the existing highway at Mangawhai Road, just short of the Auckland/Northland boundary.
Many ideas have come forth to create a Second Harbour Crossing over Waitemata Harbour to complement the aging Auckland Harbour Bridge. These include ideas for a second bridge, or a second tunnel with capacity for rail. At this stage, any meaningful progress is unlikely until at least 2025.
The Waikato Expressway has been under construction for much of the previous ten years, with most of the nine sections now funded or commencing construction. The Cambridge section which sees SH 1 bypass the township to the north was completed in late 2015. The two biggest most complex sections, the Huntly section which bypasses Huntly to the east of the township and the Hamilton section bypassing the city of Hamilton to the east, commenced construction in 2015 and 2016 respectively. All sections are estimated to be completed in 2020 meaning SH 1 from Puhoi (north of Auckland) to south of Cambridge will be entirely motorway or expressway, significantly reducing travel time through the Waikato Region by up to 35 minutes.
The Peka Peka to Ōtaki extension to the Kapiti Expressway is due to start construction in mid 2017 and is expected to be completed in 2020. The project involves upgrading 13 km (8 mi) of State Highway 1 to a four-lane expressway, from end of the existing Kapiti Expressway at Peka Peka to Taylors Road north of Otaki.
The highly controversial Transmission Gully Motorway will connect Mackays to Linden, bypassing much of Porirua City, and is due to open in 2020.
Many inner city Wellington projects are also planned for SH 1 including duplication of the Terrace Tunnel and Mt Victoria tunnels. However these projects look uncertain as another planned project, the Basin Reserve Flyover failed to obtain the necessary resource consents and an appeal was rejected in the High Court.
NZTA are constructing the Western Belfast Bypass, a spur from the Christchurch Northern Motorway that will carry SH 1 traffic away from Belfast. Belfast is a significant congestion point on the northern corridor so the bypass will help relieve congestion for motorists traveling into Christchurch via Main North Road and also via SH 74 to the Lyttelton Port. The Western Belfast Bypass will be built to motorway status as far as the Groynes and is expected to be completed in 2018.
SH 1 to the west of Christchurch along Johns Road, Russley Road, Masham Road and Carmen Road is also being upgraded to four lanes from the Groynes to Main South Road in Hornby. Some sections have already been completed while the remaining sections are currently under construction. A grade separated interchange will also be built at the intersection of Memorial Avenue, the thoroughfare which connects the city to Christchurch International Airport.
NZTA are also investigating extending the Christchurch Northern Motorway so that it bypasses the town of Woodend.
Several smaller projects are being undertaken to improve sections of SH 1. These include:
- Realigning the highway and adding a northbound passing lane at Akerama, between Kawakawa and Whangarei.
- Safety improvements to the highway between Otaika (Loop Road North) and the southern end of Whangarei (Smeatons Hill).
- Replacing the end-of-life Whirokino Trestle and Manawatu River bridges south of Foxton with new bridges.
- Safety improvements to the highway between Spring Creek and Blenheim, including a new roundabout at the intersection with SH 62 and replacing the narrow Opawa River Bridge with a new bridge.
- Bypassing the town of Edendale to the west of the Fonterra milk processing plant.
