It was previously known as the F3 to M2 link, then the M1 to M2 link after alpha numeric route numbers began to be used in New South Wales. When complete, it will link the north to the Sydney Orbital Network and form part of the National Highway route. The link between the M1 and M2 is recognised in the NSW Government's ''State Infrastructure Strategy'' and the Transport for NSW ''Long Term Transport Master Plan'' as important infrastructure for freight traffic and the wider connectivity within NSW to reduce congestion and improve traffic flow along Pennant Hills Road. == History == The M1 Pacific Motorway motorway was originally planned to continue as the Lane Cove Valley Expressway, which was to join the North Western Expressway, leading to the Sydney Central Business District via Gladesville Bridge and the Western Distributor, but those plans were cancelled in 1977. By the time the M1 Pacific Motorway was extended to Wahroonga in 1989, there was no plan for a motorway route continuing beyond that location. In 2001, at the same time as announcing commencement of the M7, the Federal Government proposed that the M7 would form part of a bypass route, with a new road branching off the M1 Pacific Motorway near Mount White and crossing the Hawkesbury River with a new high-level bridge to join the M7 at its distinct northwestern ''corner'' at Dean Park. Hence, the road would avoid the steep grades of the Mount White section of the Pacific Motorway immediately north of the existing low-level bridges across the Hawkesbury River and would be a quite direct bypass of Sydney that would be separated from much of Sydney's Commuter traffic. A study was undertaken into options for connecting the Pacific Motorway with the M7.〔http://commcons.skm.com.au/f3tosydneyorbital F3 to Sydney Orbital route study〕 At the preliminary stage of that study, the then Roads and Traffic Authority decided that the primary goal of the new road was the best possible relief of traffic on the existing route, Pennant Hills Road. Corridors for that proposal were broadly defined as types A, B and C. *Type A options were essentially from the existing end of the M1 to somewhere on the M2. *Type B corridors branched off the M1 in the vicinity of Berowra and crossed the environmentally sensitive Galston Gorge. *Type C corridors were along the general lines of the Federal Government proposal. The need to reduce traffic on Pennant Hills Road made the reduction of commuter traffic more urgent than that of traffic bypassing Sydney. As such, type B and C options were rejected early in the planning process. Four type A options were identified. All involved extensive tunnelling. One of these, following the Hornsby - Epping railway line near the M1 and underneath Pennant Hills Road towards the M2, was selected as the preferred option. On 17 February 2007, the Hon Jim Lloyd MP (the federal Minister for Local Government, Territories and Roads) announced the establishment of an independent review of the F3 to M7 Corridor Selection.〔http://www.dotars.gov.au/roads/F3toM7Review/index.aspx Review of the F3 to M7 Corridor Selection〕 The review was carried out by the Hon Mahla Pearlman AO, who is a former Chief Judge of the NSW Land and Environment Court. The report was released on 14 September 2007. The conclusions of the report were that the proposed tunnels should proceed but that planning for the longer term connection between the Pacific Motorway and the M7 should also commence immediately.〔(Review of the F3 to M7 Corridor Selection (PDF) )〕 Plans to construct the M1 to M2 link tunnels were announced in 2013.〔http://www.rms.nsw.gov.au/roadprojects/projects/building_sydney_motorways/m1_m2/documents/121216_m1_m2_community_update2_december2013.pdf M1-M2 Community Update December 2013〕 Selection of the preferred construction contractor was announced on 16 March 2014, along with the new name - NorthConnex.〔(【引用サイトリンク】url=http://www.transurban.com/140313_transurban_announces_preferred_tenderer.pdf )〕 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「NorthConnex」の詳細全文を読む スポンサード リンク
