1 Introduction This chapter introduces the project, providing a brief outline of its need, scope, and location. It also outlines the structure of this environmental impact statement (EIS). 1.1 Overview of WestConnex project The M4 Widening is a component of the WestConnex project which is the largest integrated transport and revitalisation project in Australia. The WestConnex project will link Parramatta to the central business district (CBD), Sydney Airport and the Port Botany precinct and the M5 in south- west Sydney via a 33 kilometre tolled motorway completely free of traffic signals. As shown in Figure 1.1, WestConnex is made up of the following stages: • Widening of the M4 Western Motorway (M4 Motorway) between Parramatta and Homebush (this project). • M4 East - Extension of the M4 Motorway from Homebush to Haberfield, due for completion in 2019. • M4 South - Construction of a further stage from Haberfield to St Peters via Camperdown, due for completion in 2023. • M5 - Construction of a new link from St Peters to the M5 East, as well as the duplication of the M5 East, due for completion in 2019. Currently, the M4 Motorway finishes at North Strathfield at which point traffic continues along Parramatta Road encountering multiple traffic signals generally every few hundred metres leading into the Sydney CBD. This leads to traffic congestion and unreliable travel times. When complete, the M4 Widening project and future M4 East project would together extend the M4 Motorway beyond Parramatta Road at North Strathfield to the City West Link near Haberfield. When constructed, these improvements will help by removing traffic, including heavy vehicles, from Parramatta Road and easing congestion for local travel, particularly east of North Strathfield. As a result, WestConnex will be the trigger for urban revitalisation and provide new opportunities for residential and commercial development along the Parramatta Road corridor, particularly between North Strathfield and Camperdown, making it a more attractive place to live, work and socialise. WestConnex aims to accommodate the growing transport needs of greater Sydney, strengthen access for industry to commercial centres and improve growth opportunities for local businesses. When completed, WestConnex will save 40 minutes on a typical journey between Parramatta and Sydney Airport by bypassing up to 52 sets of traffic signals, helping the city cope with an expected population increase of more than 1.5 million by 2031. WestConnex is a key recommendation of the State Infrastructure Strategy 2012-2032 (Infrastructure NSW 2012) (State Infrastructure Strategy) and was the subject of a Business Case approved by the NSW Government in September 2013. WestConnex is also identified as a key element of Sydney’s road future in the NSW Long Term Transport Master Plan (Transport for NSW 2012) (LTTMP).

The WDA is a public subsidiary corporation of the (NSW) Roads and Maritime Services (Roads and Maritime). Its role and functions are set out in Part 4A of the (NSW) Transport Administration (General) Regulation 2013. Roads and Maritime is the M4 Widening project proponent. 1.2 Project overview The M4 Widening project comprises the first stage in the delivery of WestConnex. It includes widening and upgrading approximately 7.5 kilometres of the M4 Motorway generally between Pitt Street, Parramatta and Homebush Bay Drive, Homebush (noting that the Pitt Street overpass borders the four suburbs of Granville, Holroyd, Merrylands and Parramatta). As a result of the project, access to and from the M4 Motorway would be substantially improved at Homebush Bay Drive, Homebush and Hill Road, Lidcombe (at Sydney Olympic Park). By providing an extra lane each way for motorists using this section of the motorway, it will also help alleviate congestion around the James Ruse Drive ramps and provide quicker and more reliable journeys for motorists and freight. The investment in the M4 Widening project and subsequent WestConnex stages would facilitate a step change in network performance, enabling delivery of major city shaping improvements and delivering economic growth. The M4 Widening project would include the following key features: • Construction of a new two lane viaduct for westbound traffic, on the southern side of the existing viaduct structure between Church Street, Parramatta and Wentworth Street, Granville. • Reconfiguration of the traffic lanes on the existing viaduct structure to four lanes eastbound and two lanes westbound (making a total of four lanes in each direction). • Construction of a new bridge/viaduct over Duck River at Auburn. • Widening of the existing motorway to the south of the westbound carriageway between Wentworth Street, Granville and Duck River, Auburn. • Widening of the at-surface carriageway of the motorway predominantly within the existing motorway corridor (utilising both the existing median and verge areas), between Junction Street, Auburn and Homebush Bay Drive, Homebush to provide four traffic lanes westbound and four traffic lanes eastbound. • Construction of a new westbound G-loop on-ramp to the M4 Motorway from Homebush Bay Drive, Homebush. • Construction of a new eastbound on-ramp to the M4 Motorway from Hill Road, Lidcombe. • Provision of Intelligent Transport Systems (ITS) infrastructure for motorway operations. • Provision of road infrastructure and services to support the future implementation of smart motorway (Managed Motorway) operations. • Widening and/or lengthening of existing ramps at Church Street, James Ruse Drive, Silverwater Road, Hill Road and Homebush Bay Drive. • Provision of tolling infrastructure such as gantries and control systems. • Provision of new and modified noise barriers. • Provision of new asphalt wearing surface to the existing M4 Motorway.

Figure 1.1 shows the regional context while Figure 1.2 shows the project location and key features. The project extends from Pitt Street, Parramatta in the west to east of the Homebush Bay Drive interchange at Homebush in the east. The project traverses the suburbs of Merrylands, Parramatta, Holroyd, Granville, Silverwater, Auburn, Lidcombe, Sydney Olympic Park, Homebush and Homebush West. The project spans four local government areas (LGAs) being Holroyd, Parramatta, Auburn and Strathfield. 1–4 M4 Widening Environmental Impact Statement WestConnex Delivery Authority GREAT WESTERN HIGHWAY HARRIS CHURCH ROSEHILL STREET PAR RAMATTA PARK ¹ New viaduct New bridge over WENTWORTH Silverwater Road connections Duck River POINT JAMES RUSE DRIVE !
