Artist impression of the Concord Road interchange, Concord - concept only WestConnex s M4 East will extend the M4 Motorway with two new 5.5 kilometre tunnels from Homebush to Haberfield, providing a bypass of Parramatta Road and connection to the City West Link. WestConnex is part of Tomorrow s Sydney. The Concord Road Interchange will be a key entry and exit point for the M4 East tunnels, connecting road users to Homebush and Haberfield. The tunnels would bypass Parramatta Road, easing traffic congestion on local streets and enabling urban renewal of precincts along the Parramatta Road corridor. Concord Road Interchange Eastbound entry and westbound exit to M4 East tunnels at Concord would connect to Concord Road, Parramatta Road and the City West Link at Haberfield, and the existing M4 Motorway at Homebush. On-ramp bridge to the existing M4 Motorway (westbound) from Concord Road (southbound). Pedestrian bridge to provide pedestrian access from the eastern side of Concord Road over the new on and off ramps. Concord Road bridge widened for an eastbound on-ramp to the M4 East tunnel from Concord Road (northbound). Traffic lanes on the existing M4 Motorway adjusted east of Sydney Street to the intersection of Parramatta Road to accommodate on and off ramps below Concord Road bridge. Remove existing on-ramp from Concord Road (northbound) to the existing M4 Motorway (westbound). Would be replaced by new M4 westbound on-ramp from Parramatta Road west of George Street. Remove left turn to existing M4 Motorway for Parramatta Road eastbound traffic. Queen Street cycleway on-ramp. Standard hours of work Surface works Monday to Friday, 7am to 6pm. Saturday, 8am to 1pm. Generally, no work on Sunday or public holidays. Some surface work would be carried out at night in accordance with conditions of approval and Environment Protection Licence conditions. Tunnelling work 24 hours a day, seven days a week. No change to traffic movements at Concord Road/Sydney Street M4 off-ramp.
Construction sites and programs A number of construction sites would be established to build the Concord Road Interchange. These consist of civil sites for work that would take place on the surface, such as road works and tunnel support facilities; and tunnel sites to construct the M4 East tunnels. Once work is completed residual land would be rehabilitated and its future use would be determined in consultation with relevant authorities. Concord Road west civil site between Concord Road, Sydney Street and the M4 Motorway, and Concord Road, Sydney Street and Carrington Lane. Concord Road south civil site eastern side of Concord Road immediately adjacent to the M4 Motorway and between Alexandra Street and Ada Street extending under Concord Road to connect with the west civil site. Concord Road tunnel site eastern side of Concord Road, between Sydney Street and Alexandra Street. This would be the main tunnel construction site for the western end of the M4 East project. Figure 1: Concord Road Interchange construction sites - Indicative only
Table 1: Concord Road Interchange indicative construction program Construction movements Where possible heavy vehicles would not use local roads. The signalised intersection at Sydney Street and Concord Road would be modified to provide access and traffic control to the Concord Road tunnel site on the eastern side of Concord Road. Light vehicles (including light delivery vehicles) would enter the site at Alexandra Street and Ada Street and exit via the Sydney Street and Concord Road signalised intersection. Access to and from the west civil site would be via Sydney Street. The Concord Road south site would be connected to this site by excavating under the northern span of the existing Concord Road bridge over the M4 Motorway. The table below is indicative of the number and type of construction vehicle movements in and out of the proposed Concord Road construction sites. Table 2: Indicative construction vehicle movements at the Concord Road civil and tunnel site
Changes to local road access During the construction of the M4 East there would be changes to local roads in Concord. Table 3: Proposed temporary road changes Table 4: Proposed permanent road changes
Minimising impacts on the community WestConnex is working to minimise the impact of construction on the community, with most of the work proposed to occur underground. However, some work needs to occur on the surface to construct the entry and exits to the tunnel and tunnel support facilities. WestConnex would work directly with affected residents to minimise any impact. The M4 East Environmental Impact Statement outlines in detail the measures to mitigate any potential construction or operational impacts. Minimising noise WestConnex would monitor noise during the construction of the M4 East where required, and directly work with affected residents to mitigate noise. The EIS recommends noise barriers to the east of the Concord Road Interchange, which would be further investigated during detailed design and in consultation with the community. To reduce the potential for an increase in noise adjacent to the Concord Road Interchange WestConnex would, where required: Provide noise barriers and an acoustic shed to house tunnelling activity. Undertake noisy work during core work hours, where possible. Ensure all equipment is shut down when not in use and nontonal reversing beepers are used. Ensure there are periods where construction work is not scheduled to give residents respite from the works. If actual noise levels were above predicted levels WestConnex would consider additional noise mitigation measures. Protecting property Pre-condition building surveys would be carried out on properties and structures within 50 metres from the outer edge of the tunnels and within 50 metres of all surface work. Future land use WestConnex would work to improve the visual amenity around the Concord Road Interchange area following the completion of the M4 East by providing a landscape buffer to physically separate properties from the widened Concord Road and new infrastructure. The creation of two large island areas of trees and grass would form part of the new interchange landscape, which would be further developed through detailed design and in consultation with the community. Local heritage During construction heritage items and heritage materials would be preserved where possible. Heritage items directly impacted by the project would be photographed. The finding of any archaeological items during construction would be subject to stop work and evaluation procedures. Partial acquisition along the Concord Road frontage of the Sydney Cheil Uniting (formerly Wesley) Church would be required. Appropriate landscaping, noise treatments, and opportunities to increase access to green space and parking are being explored. Some heritage items within the Powells Creek Heritage Conservation Area would be impacted by the project. The interchange would also require the removal of approximately 16 to 18 street trees at the Concord Road ends of Sydney and Edward streets, which are listed as heritage items on Canada Bay LEP 2013. Landscaping plans would be developed in consultation with the community. Keeping you informed We are committed to keeping you informed and will provide regular information on the M4 East through direct mail and email notifications, community updates, advertising and other consultations.

Tomorrow s Sydney In the next ten years, another million people will call Sydney home. The Australian and NSW governments are building the infrastructure to support Tomorrow s Sydney, which will deliver an integrated transport solution including public transport and critical road infrastructure. WestConnex is one of the flagship projects in delivering Tomorrow s Sydney. WestConnex will widen and extend the M4 and M5 and join them together to form a continuous, free-flowing motorway with connections to the city, airport and port. WestConnex will provide relief to the hundreds of thousands of road users struggling in traffic every day and help return local streets to local residents.
