Auckland Northern Motorway
Encyclopedia
The Auckland Northern Motorway (known locally as the Northern Motorway, and historically known as the Auckland–Waiwera Motorway) is a major motorway in the Auckland Region
of New Zealand, linking central Auckland City
and Puhoi
in the Rodney District
, via the Hibiscus Coast
and North Shore
. The motorway forms part of State Highway 1.
The Northern Motorway is 38 kilometres (23.6 mi) in length, with 15 junctions including termini. Until the end of the 1980s, the Northern Motorway was largely associated with the Auckland Harbour Bridge
as a connection between central Auckland and the North Shore, but since 1994, has been extended to Puhoi to become the primary motorway route between the Auckland urban area, the Hibiscus Coast satellite towns, the northern Rodney District, and further afield to Northland. Between the 1959 opening of the motorway and 1984, toll
s were collected on the Auckland Harbour Bridge, and since 2009, tolls have been collected on the Northern Gateway Toll Road, the northernmost section of the motorway, bypassing the Hibiscus Coast.
The Northern Motorway sees heavy traffic: the section between Esmonde Road and Cook Street has an annual average daily traffic (AADT) count of over 100,000 vehicles per day, with around 155,000 vehicles per day crossing the Harbour Bridge.
. The motorway leaves the two-lane coastal road between Puhoi and Waiwera on the northern side of Johnstone's Hill, then tunnels under the aforementioned hill in 340-metre long twin tunnels.
The initial 7 km section of the Northern Motorway is an automated-toll road, and is also known as the Northern Gateway Toll Road. The electronic toll-registering gantry is located at the southern end of the section. At the first junction, west of Orewa, the motorway becomes free-use.
The next 17 km to Albany runs through a mainly rural environment. An interchange at Silverdale provides access to the Hibiscus Coast
and the Whangaparaoa Peninsula
, and also allows access to the alternative route north via State Highway 17 for those not wishing to pay the toll (the Orewa interchange can also be used, but requires driving through local residential areas). South of the junction at Dairy Flat is the motorway's only service centre, which serves northbound traffic, and is the toll cash-payment point for northbound traffic.
The motorway then descends steeply into the northern suburbs of North Shore City, the northern of Auckland's four cities. Crawler lanes are provided for heavy vehicles between Oteha Valley Road and Greville Road. The Greville Road interchange was until 1999 the northern terminus of the Northern Motorway, with the current northbound entrance and exit ramps follow the old motorway formation down to the roundabout with Albany Highway.
The motorway proceeds south-east through the suburbs of the North Shore, with interchanges at Upper Harbour Highway, Tristram Avenue, Northcote Road, and Esmonde Road allowing access to the suburbs. The Upper Harbour Highway interchange is the northern terminus of the incomplete Western Ring Route
, which in future will provide an alternative north–south motorway route for traffic travelling through Auckland.
At Esmonde Road, the motorway turns south-west to follow the northern shore of the Waitemata Harbour
to Northcote Point, where the motorway crosses the harbour over the Auckland Harbour Bridge
. The Harbour Bridge has a contraflow system
on it which allows five lanes southbound and three northbound during morning rush hour, five lanes northbound and three southbound during evening rush hour, and four lanes each way at other times. The lanes are separated by a moveable median barrier.
Coming off the Harbour Bridge, the road turns sharply to head eastwards towards the Auckland city centre
. An interchange with Fanshawe Street allows motorway traffic to access the northern end of the city centre, and also allows lanes to be dropped ahead of the narrow four-lane Victoria Park Viaduct
. The motorway then turns south-east across the Victoria Park Viaduct, and travels down the western side of the city centre, with an exit at Cook Street to allow access to the southern end of the city centre.
The motorway emerges at the top of the Central Motorway Junction
("Spaghetti Junction"). The Northern Motorway terminates at the exit to the Northwestern Motorway, with the mainline becoming the Southern Motorway
.
for human analysis.
Vehicles can pay up to 180 days before travel and up to 5 days after, either at the self-service kiosks located at the Dairy Flat Service Centre for northbound traffic and at a rest stop 1 km north of the beginning of the motorway for southbound traffic, by account, by telephone, or online. If the toll is not paid within five days after travel on the toll road, a payment notice for the toll plus a $4.90 administration fee is sent to the registered owner of the vehicle. If payment is still not received, a $40 toll infringement fine is issued, and is treated the same way as regular traffic infringement.
As of 1 June 2010, the tolls for a single one-way trip on the Northern Gateway Toll Road are:
From its opening to 31 May 2010, motorcycles travelled on the toll road free of charge.
Each toll costs 78 cents to collect, as of May 2010.
Initially, the motorway was limited access, with all ramps facing towards the Harbour Bridge. Tolls for the Harbour Bridge were collected manually, with cars initially paying 2/6 to cross the bridge (equal to 25 cents in today's New Zealand dollar
, equivalent to $5.00 in 2010 dollars).
In 1962, the Victoria Park Viaduct
opened, and the motorway was extended south from Fanshawe Street, over the viaduct, to Cook Street/Wellington Street. In 1969, the motorway was extended northwards from Northcote Avenue to Tristram Avenue, and the Auckland Harbour Bridge's clip-on lanes opened, widening the bridge from four lanes to eight lanes.
In 1978, the motorway was extended south to meet the Southern Motorway at Nelson Street/Hobson Street. This allowed motorway traffic a clear run from Tristram Avenue to St Stephens, on the northern side of the Bombay Hills.
In 1984, the Northern Motorway was extended northward to Sunset Road, near the present Upper Harbour Highway interchange, with a two-laned expressway continuing from Sunset Road to Albany Highway at Albany Village
. The motorway ended at a set of traffic lights on the top of a hill, giving limited visibility to motorway traffic. On 30 March 1984, the last tolls were collected for the Harbour Bridge, making the entire Northern Motorway free of charge from 31 March 1984.
In the 1980s, tidal flow was introduced on the Auckland Harbour Bridge to assist with peak flows on the Northern Motorway between the North Shore and central Auckland. The two central lanes were made reversible to allow a 5+3 split favouring the peak direction (southbound in the morning, northbound in the evening) during peak hours, and 4+4 off-peak. The lanes were controlled by overhead signals, which some motorists on the Motorway ignored and were killed when they collided head-on
with oncoming traffic - between 1 January 1989 and 27 November 1989, some five people died as a result of collisions involving the so-called "suicide lanes". In 1990, a moveable barrier was installed to separate the traffic flows.
The expressway between Sunset Road and Greville Road was upgraded and became a part of the Northern Motorway in 1994. A new interchange was created at Upper Harbour Highway and Constellation Drive to replace the Sunset Road intersection.
The late 1990s saw the construction of the first stages of the Albany to Puhoi Realignment (ALPURT) – a 27 km extension of the Northern Motorway, bypassing Albany Hill and the Hibiscus Coast. The first section, ALPURT A, opened between Greville Road and Silverdale on 20 December 1999. At 13 km in length, it was the longest section of motorway to open at once in New Zealand. At the same time, ALPURT B1, a two-lane expressway between Silverdale and the back of Orewa opened.
In 2006, an upgrade to the Central Motorway Junction saw ramps open between the Northern Motorway and the Northwestern Motorway, and the Northern Motorway and Grafton Gully. Beforehand, traffic travelling from the Northern Motorway to the Northwestern Motorway or Grafton Gully had to exit at Cook Street and travel through local city streets to connect to Waitakere or the Port of Auckland.
ALPURT B2, the Northern Gateway Toll Road, opened on 25 January 2009 between Orewa and Puhoi. The Northern Gateway Toll Road was the first automated toll road in New Zealand, and the first under the authority of the New Zealand Transport Agency
. At the same time, ALPURT B1 was upgraded to motorway standard to complete the Northern Motorway from central Auckland to Puhoi.
is closely associated with the motorway. The first section of the 6.2 km bus rapid transit
road opened in January 2008, and runs along the eastern side of the motorway between the Constellation Drive interchange and the Esmonde Road interchange. An additional 2.5 km southbound bus lane, opened in 2009, runs from Esmonde Road to the Harbour Bridge. Dedicated ramps connect the busway with the Northern Motorway at Constellation Drive and at the Albany Bus Station near the Oteha Valley Road interchange.

Toll
Tolls for the Northern Gateway Toll Road are collected electronically, using an automated toll plaza just north of the Grand Drive interchange. The automated toll plaza uses automatic number plate recognition to identify the vehicle, from which the number plate is optically read and details checked against the New Zealand Transport Agency's (NZTA) database, any pre-payment made or account open for that particular vehicle. Additional sensors detect the size of the vehicle, to help prevent misreads of registration plates and to notice plate swaps between cars and trucks.

History
The first section of the Northern Motorway opened on 30 May 1959, in conjunction with the opening of the Auckland Harbour Bridge. The first section totalled 7.4 km, stretching from Northcote Road to Fanshawe Street. On its opening day, 51,000 vehicles crossed the Harbour Bridge, with southbound traffic backing up for unprecedented 10 km north of the toll plaza (near the present Stafford Street exit) with vehicles wishing to cross the bridge for the first time. Initially, the Auckland Harbour Bridge Authority owned and operated the motorway between Fanshawe Street and the toll plaza, while the National Roads Board (the predecessor to the New Zealand Transport Agency) operated the remainder of the motorway from the toll plaza to Northcote Road.Initially, the motorway was limited access, with all ramps facing towards the Harbour Bridge. Tolls for the Harbour Bridge were collected manually, with cars initially paying 2/6 to cross the bridge (equal to 25 cents in today's New Zealand dollar

Under Construction
As of July 2010, the following projects are currently under construction:- Auckland Harbour BridgeAuckland Harbour BridgeThe Auckland Harbour Bridge is an eight-lane box truss motorway bridge over the Waitemata Harbour, joining St Marys Bay in Auckland with Northcote in North Shore City, New Zealand. The bridge is part of State Highway 1 and the Auckland Northern Motorway...
Clip-on Strengthening - The Harbour Bridge's clip-on lanes (often dubbed the "Nippon clip-ons") were added in 1969 to double the bridge's capacity. The clip-ons are showing signs of fatigue, and heavy vehicles have been banned from using the outside clip on lanes in each direction. Work is currently underway to strengthen the clip-ons to extend their life by 20–30 years, and is expected to be completed by February 2011, costing NZ$45 million.
- Victoria Park TunnelVictoria Park ViaductThe Victoria Park Viaduct is a major motorway viaduct carrying the Auckland Northern Motorway over the Victoria Park area in Auckland City, New Zealand...
- Victoria Park is currently crossed by a narrow four-lane viaduct, which creates a bottleneck for traffic travelling between the Auckland Harbour Bridge and the Central Motorway Junction. Construction of a 440 m long cut-and-cover tunnel to the west of the existing viaduct began in January 2010. Once this is completed in 2012 the tunnel will carry three lanes of northbound traffic, while southbound traffic will use the four lanes of the existing viaduct. In addition, works are being carried out to allow connection between the Auckland Harbour Bridge and the new tunnel and existing viaduct - widening the road to ten lanes total and extending the Harbour bridge moveable median barrier to Fanshawe Street. The project is estimated to cost NZ$430 million, and was fast-tracked by the New Zealand Government in March 2009 as one of its seven "Roads of National Significance" projects.
Proposed
Several other major projects are proposed for the Northern Motorway in the future. From south to north they are:-- Second Harbour Crossing - A second crossing over the Waitemata Harbour between the Esmonde Road intercahnge and the Central Motorway Junction is under investigation to supersede or completely replace the existing Auckland Harbour Bridge. The currently preferred alignment is from the Onewa Road interchange straight across the harbour to the Western ReclamationWestern ReclamationThe Wynyard Quarter is a reclaimed piece of land on the Waitemata Harbour at the western edge of the Auckland waterfront, New Zealand....
, then to the existing motorway near the Cook Street Interchange. The preferred crossing is quadruple tunnels, with two tunnels for general traffic and two for public transport, with pedestrians and cyclists using the existing bridge, but a bridge option in also under consideration. If the second crossing proceeds to construction stage, the project is estimated to cost up to NZ$4 billion.
- SH1-SH18 Motorway Interchange - Currently the Upper Harbour Motorway (State Highway 18) and the planned Western Ring RouteWestern Ring RouteThe Western Ring Route is a motorway system being constructed in Auckland, New Zealand.

connect with the Northern Motorway at the Constellation Interchange. As a full diamond configuration interchange controlled by traffic lights, this will be the only section of the Upper Harbour Motorway after 2012, and eventually the Western Ring Route, that is not to a motorway standard. The New Zealand Transport Agency is currently looking at upgrading this interchange, with investigation completed by 2010-2011.
- Penlink - A planned link road between SH1 and the Whangaparoa Peninsula. This road would connect with the Northern Motorway at a new interchange near Redvale. This road was originally planned as a toll road by the Rodney District Council. In 2008 the New Zealand Government announced that Penlink would be fully funded by a new regional fuel tax. However in 2009 this decision was reversed, making the project currently uncertain.
- Puhoi to Wellsford - A 34 km four-lane motorway or expressway from the current terminus of the Northern Motorway at Puhoi to north to Wellsford. Much of the route would require a substantial realignment of the present SH1, and would bypass Warkworth to the west. This project is currently at the investigation stage, and could be progressed in stages. Part or all of this road may be tolled. The project is one of the seven "Roads of National Significance" announced by the Government in March 2009. The Puhoi-Wellsford route has proven to be particularly controversial, with critics, including financial commentators and public transport advocates, labelling it the "Holiday Highway" and pointing to a poor benefit-cost ratio. http://www.stuff.co.nz/sunday-star-times/business/4366408/Going-down-the-wrong-road http://www.bettertransport.org.nz/2010/12/1488/
