147-531: The need for the project arose from the rapid and sustained growth of the northern suburbs of Perth during the 1970s and 1980s, which had placed a considerable strain on infrastructure, including the bus system and the Mitchell Freeway . However, prior to the opening of the railway, the proposal was controversial as many in the community believed that upgrading the Mitchell Freeway or providing

13818-403: The intersection of Fitzgerald and Roe streets in central Perth. The crossing allowed buses coming from Wellington Street Bus Station to connect with Fitzgerald Street and then run to the northern and north-eastern suburbs. Due to the need to construct a rail tunnel under Roe Street, it was considered unsafe and impractical to retain the existing level crossing, because it would be situated very near

13965-424: The left lanes of the Mitchell Freeway northbound. The project commenced in February 2013 and was completed in December 2013. In October 2012 the state government announced that the freeway's interchange with Reid Highway would be upgraded with the installation of extra turning lanes and traffic lights.

At the time, members of the then Liberal - National Coalition Opposition, and local community groups, rallied against what they claimed was the lack of the then government's commitment to transport in

14700-571: The more interesting notes to the Allco proposal was the nature of the financing arrangements it was proposing. At the time of the proposed financing deal, interest rates in Australia were around 16-17%, placing a significant burden on companies in their business dealings. To work around this, Allco proposed a financing structure that involved a cross-border financing arrangement in Japan. It also required

14847-408: The most appropriate form of rapid transit service for the northern suburbs." The study was commenced in early 1988 under the auspices of the then Minister for Transport and Small Business, after receiving Cabinet approval 10 November 1987. Due to the budget position of the then Department of Transport, it was not possible to fund the nine-month project from within its existing budget, which necessitated

15288-463: The northern corridor . Opposition Leader Barry MacKinnon called on the state government to put plans to construct a new northern suburbs highway on hold, and redirect funds to upgrading and extending the Mitchell Freeway instead. It is almost beyond belief that the Government would contemplate spending $ 41 million on another new arterial route in the northern suburbs when the Mitchell Freeway

15435-632: The northern corridor, Donovan Research was engaged during 1987 to undertake focus group and telephone research to determine information on the following key points: The focus groups consisted of two sub-groups of participants, one consisting of public transport users residing within established suburbs, and the other of public transport users from newer and developing suburbs. Combined within these sub-groups were subsets of both regular and irregular users, with regular users being defined as those using public transport at least once per week. The participants from both sub-groups all held similar views in relation to

15582-424: The northern suburbs of Perth , Western Australia, linking central Perth with the city of Joondalup . It is the northern section of State Route 2 , which continues south as Kwinana Freeway and Forrest Highway . Along its length are interchanges with several major roads, including the Graham Farmer Freeway and Reid Highway . The southern terminus of the Mitchell Freeway is at the Narrows Bridge , which crosses

15729-552: The public debate over the future of public transportation in the northern corridor, Transport Minister Pearce claimed that the NSTS would never be built under a Liberal coalition government. Opposition Leader Barry MacKinnon stated that charge was "totally untrue". As part of the analysis of a rail service in Perth's northern corridor, a comprehensive study was undertaken in 1989 to establish the best route and potential station options. The locations of possible station sites included: At

15876-481: The public transport; that of bus overcrowding, poor connections, poor timing, and poor route design impacted negatively on their perceptions and opinions of public transport. Over 43% of the participants described the public transport system as it currently stood as either poor or very poor. In its 1986 election campaign platform, the Australian Labor Party stated that "A study will be conducted on

16023-470: The purchase of a 22 additional two-car electric trains,now known as the A-series train . The remaining cost of the trains was to be funded from a financing package being drafted by the government. The proposed rail line would run along the centre of the Mitchell Freeway , and designed to closely link the new rail infrastructure with bus services through the construction of several interchange stations along

16170-487: The realignment were included as part of the project cost, the rebuilding of the section of road in the realigned section was funded separately from the project, using regular road funding sources. The transit system was designed to provide for a rapid service, allowing rail cars using the line to operate at speeds of 110 km/h (68 mph), which would allow a journey from Perth to Joondalup to be completed in approximately 20 minutes. Stations to be constructed as part of

Proctor claimed that the system had been selected for use in connecting two shopping centres and other local infrastructure in Campbelltown, New South Wales , but the Acting Deputy Director General was not impressed with the concept having shifted a number of times in conversation and there still not a working prototype in place for evaluation. Retired engineering design consultant, John Stephens, told

17052-440: The route. The proposed project initially included: Related to the project was the realignment of the Mitchell Freeway between Loftus and McDonald Streets. At the time, the northbound and southbound carriages of the freeway in this section were constructed next to each other. To allow for the rail corridor down the middle of the freeway, that section of road required realignment. While necessary bridges and some associated works for

17199-654: The services prior to reaching the maximum load point, defined by the report as Scarborough Beach Road. A number of theoretically innovative ideas for possible transport systems were put forward by various people within the Western Australian business and transport communities, but ultimately rejected. One proposal, from Tom Proctor, Managing Director of Modular Commuting Systems, was for a "Personal Vehicle Fast Track System" , in which car-like vehicles travelled automatically, suspended from an overhead beam. The vehicles were then used as electronically driven cars on

17346-399: The short distance between the interchanges. Greenwood is located north of Warwick Road and east of the freeway. The following two interchanges, after 2.6 kilometres (1.6 mi) and 2.1 kilometres (1.3 mi) respectively, are with Hepburn Avenue and Whitfords Avenue .

17934-512: The then Office of the Director General of Transport. The report looked at Perth's transport needs into the 21st century and beyond, at a broad strategic level. It provided some strategic travel forecasts, and made a limited evaluation of rapid transit options for the northern corridor. By the late 1980s, the Mitchell Freeway , along with major arterial routes servicing the northern corridor, were constantly clogged during peak hour, with

18081-511: The third lane began in February 2013, the 4.5-kilometre (2.8 mi) section from Hepburn Avenue to Ocean Reef Road opened in August 2013 with the remaining section to Hodges Drive completed in early 2014.

18375-444: The time, a possible deviation of the rail alignment was considered to directly service the suburb of Innaloo . However, this idea was rejected by both the project coordinators and the public at large due to the significant cost, lack of identifiable benefits, and environmental impact. The study predicted that by 2001, the line would have 13,000 passenger boardings during peak hour. Over 12,000 of these passengers were predicted to board

18522-526: The tunnel entrance, and so make impossible for train drivers to see any vehicles on the crossing and take evasive action. That led to the construction of the Fitzgerald Street Bus Bridge. Estimated in 1991 to cost $ 2.88 million, the bridge was designed as a flyover from Roe Street, accommodating two bus lanes, and a shared use path for pedestrian and cycle movements. To construct the bridge, a significant amount of land then occupied by
