It is part of State Highway 1. It is in length, with 15 junctions. Until the end of the 1980s, it was largely associated with the Auckland Harbour Bridge as a connection between central Auckland and the North Shore, but since 1994 it has been extended to Puhoi to become the primary route between the Auckland urban area, the Hibiscus Coast satellite towns, the northern Rodney district, and Northland. Between the 1959 opening of the motorway and 1984, tolls 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.〔(【引用サイトリンク】title= State Highway Traffic Volumes - Data Booklet 2005-2009 - New Zealand Transport Agency )〕 ==Route== The Northern Motorway starts near Puhoi, in the former Rodney District. It leaves the two-lane coastal road between Puhoi and Waiwera on the northern side of Johnstone's Hill, then tunnels under the hill in 340-metre long twin tunnels. The initial 7 km section is an automated-toll road, also known as the Northern Gateway Toll Road. The electronic toll-registering gantry is at the southern end. At the first junction, west of Orewa, the motorway becomes toll free. 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 access to the alternative toll-free route north via Urban Route 31 (formerly State Highway 17). 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 the former North Shore City, the northern of Auckland's four former 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, with the current northbound entrance and exit ramps following the old formation down to the roundabout intersection 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 will provide an alternative north–south motorway route around Auckland. At Esmonde Road, the motorway turns south-west to follow the northern shore of the Waitemata Harbour to Northcote Point, where it crosses the Auckland Harbour Bridge. The 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 bridge, the road turns sharply to head eastwards towards the Auckland city centre. An interchange with Fanshawe Street allows access to 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 for the southern end of the city centre. The motorway emerges at the top of the Central Motorway Junction ("Spaghetti Junction") and terminates at the Northwestern Motorway, becoming the Southern Motorway. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Auckland Northern Motorway」の詳細全文を読む スポンサード リンク
