M4 Motorway (Sydney)
The M4 Motorway is a dual carriageway partially tolled motorway in Sydney, New South Wales, Australia that is designated as the M4 route. The M4 designation is part of the wider A4 and M4 route designation, the M4 runs parallel/below ground to the Great Western Highway and Parramatta Road (A44). The M4 route number comprises two connected parts: Approximately of the motorway-grade road is not tolled, being that section of the road between and . The WestConnex section between and , known as WestConnex M4 or New M4, is tolled as part of WestConnex. The M4 cycleway  runs parallel to the M4 Motorway between Sydney Olympic Park and South Wentworthville. Sections. Alignment. The first main road west from Sydney was the Great Western Highway, shown above in orange. The County of Cumberland planning scheme provided for a modified route west, much of which was later built as the M4 Western Motorway. With the opening of the M4 East tunnel in 2019, the M4 extends as far east as Dalhousie Street, Haberfield. M4 Western Motorway. The M4 Western Motorway was originally constructed in several stages as the F4 Western Freeway between the late 1960s and the mid-1980s, with  the first section between Emu Plains and South Penrith over the Nepean River opened in 1971. On the basis of a pre-election promise made by the NSW Premier Neville Wran in 1976, all land reserved for the expressway between and the (then) eastern termination point at Strathfield was sold off to property developers or declassified as a freeway corridor in 1977 by the State Government. The F4 Western Freeway from to was opened on 16 December 1982 by Premier Wran. However a lack of funding resulted in the Wran Labor government halting plans to construct the final stage between  and in 1985. In December 1989 work to construct this stage began as a Build-Own-Operate-Transfer project. In return for funding construction StateWide Roads, the consortium awarded to build the stage, was given permission to toll the section between James Ruse Drive and Silverwater Road as traffic volumes on this section were significantly higher than between Mays Hill-Prospect and would allow a shorter toll period with lower tolls. The consortium would also widen the section between James Ruse Drive and the newly constructed Homebush Bay Drive to six lanes. The Mays Hill to Prospect section opened in  May 1992 and an initial of a $1.50 toll was implemented. The concession held by StateWide Roads ended on 15 February 2010, with operation of the motorway returned to the Roads and Traffic Authority and the toll removed. At the time, StateWide Roads was owned by Transurban (50.6%) and Utilities Trust of Australia (21.5%). The Motorway is mostly three or four lanes wide in either direction, and carries constant heavy traffic during daylight hours, seven days a week. Built as a four-lane motorway, it was widened to six lanes during 1998 to 2000, but this did little to  ease the congestion. Originally planned in the mid-1950s to start in the Sydney central business district, the eastern section was built only as far west as Pyrmont, as part of the North West Expressway, or F3, a freeway that would connect the Sydney and Newcastle central business districts. This section is now part of the Western Distributor. From there it was to have joined with the Western Expressway, the F4, and the Southern Expressway, the F6, in Glebe. At the western end of the Western Freeway as it was known in the late 1960s was to be routed through the  Mitchell's Pass area through to , however due to protests and the fact that the historic Lennox Bridge was very close to the intended pathway, it was decided to terminate the road at Russell Street, until a solution could be later found. This would have bypassed the Lapstone Hill area and avoided the sharp bends as the road enters Glenbrook. In December 1989 the extension of the freeway from Russell Street, west to the Great Western Highway in the vicinity of Governors Drive would bypass the narrow and winding section of the Great Western Highway, including the historic Knapsack Bridge . In June 1993, the new section of freeway between Emu Plains and was opened to traffic. In 2013, the state government announced the intention to implement a 'Managed Motorway' scheme on the M4 over the coming years to improve traffic flow. Mechanisms to be used include improved Variable Message Signs, Ramp metering signals, dynamic speed and incident management, and an upgrade of the Emergency Telephone System. The M4 Western Motorway used to be part of the Sydney Metroad 4 until 2013, when the new M4 route designation was proclaimed along the whole motorway. The section between Church Street in and  the eastern end at was widened as part of stage 1 of WestConnex works. Construction commenced in March 2015. In November 2015, it was announced that toll points would be reinstated on this section from 2017 to cover costs of the WestConnex project (upgrading and M4 East). The toll was introduced on 15 August 2017. M4 East. Up until 2019, the eastern end of the M4 was at North Strathfield, some from the Sydney central business district. Over the years a number of proposals were made to extend the M4 east towards the city. One plan in the 1990s involved  extending the M4 eastwards by approximately so that it would subsequently end in Ashfield and be continuous with the City West Link. Further planned upgrades to the City West Link would mean commuters going west out of the city could get to Parramatta without passing through traffic lights. The government proposed a subsequent $7 billion plan for M4 East in July 2002, including three options: All three options would run below or parallel to Parramatta Road and/or City West Link. The short tunnel option was preferred for having lower costs both during construction and operation. The long tunnel option  was considered to have the potential to increase congestion on the approaches to Anzac Bridge, causing eastbound queues to extend into the tunnels. The slot option could be constructed at a similar cost to the short tunnel, however, it was considered to not provide the same level of traffic benefits as the short tunnel option. Additionally, the option would need to acquire additional properties and the construction period for this option would be longer. Between 2003 and 2004, the preferred short tunnel option for M4 East was exhibited. Members of the government were divided over the M4 East proposal and  ultimately did not proceed with it in early 2005 due to community opposition. The preferred option eventually formed the basis of the concept design for the M4 East project of the WestConnex. In the month prior to the 2011 state election, the NRMA released a report in which it recommended building a tunnel to connect the end of the M4 at Concord and the start of the City West Link, relieving Parramatta Road of enough traffic to convert it into two lanes for slower-moving local traffic, two lanes of light rail and a cycleway. The report argued that this  would allow Parramatta Road to be transformed with medium-density housing, shops and cafes and that the $10.04 billion in additional stamp duty and other revenues from this would pay for the $7.38 billion price tag of the project. In October 2012, the NSW Government announced their commitment to deliver the WestConnex project, involving widening the existing M4 motorway as well as extending it east with a tunnel from North Strathfield to Taverners Hill. The project also involved duplicating the M5 East tunnel and building a new tunnel linking the M4 and M5 motorways. In June 2015, the  tender to design and build the M4 East was awarded to Leighton Contractors, Samsung and John Holland. Located beneath Parramatta Road, the dual-tunnel was funded through a $1.8 billion grant from the NSW Government and, from the Australian Government, a $1.5 billion grant and concessional loan of up to $2 billion, plus user tolling. The M4 East opened to traffic on 13 July 2019 and tolls were levied on both the M4 East Tunnel ($4.41 in 2020, comprising a flagfall and a change per distance travelled, subject to indexing) and the widening of the M4  between Parramatta and Homebush (base of $4.21 each way, subject to indexing). Both tolls will continue until 2060. M4–M5 Link (M4–M8 Link). Stage 3 of the WestConnex scheme will see a new motorway connection running from the end of the M4 at Haberfield to connect with the airport and the M8 Motorway (formerly the New M5) at St Peters, along with an interchange at linking to the Anzac and Iron Cove bridges. This section, currently under construction, aims to reduce travel times between Western Sydney and Port Botany while removing heavy vehicles from surface streets in the  Inner West. This section is due to open to traffic in 2023. It is unknown what the route designation in this section will be. M4 Smart Motorway Project. In July 2019, the NSW government announced its M4 Smart Motorway Project which involves widening the on and off ramps for the untolled section of the motorway between Lapstone and Mays Hill, including the installation of overhead gantries with variable speed limit displays and traffic signals on the on-ramps between Orchard Hills and Mays Hill for traffic metering during peak periods. Toll. The WestConnex section of the M4 between Church Street , and are tolled by distance travelled as part of the WestConnex. Toll points are located at entrances and exits along this section. The toll charge consists of: Tolls for heavy vehicles are triple of cars and motorcycles. Toll prices increase by 4% or the consumer price index (CPI) every year, whichever is greater, until 2040, after which CPI will apply. A toll point was previously introduced between James Ruse Drive and Silverwater Road in both directions until the toll was removed on 16 February 2010, when the M4 ownership was returned to the state government.
