With Sydney’s population set to increase by more than one million people during the next 10 years, the city’s motorway and public transport systems are being upgraded to cope with extra demand.

WestConnex is one of many projects underway to address the needs of a growing Sydney. 

The NSW Government is investing $41.5 billion in transport projects during the next four years – including public transport and roads (2016–17 NSW Budget).

Public transport investment includes upgrading the bus fleet, the CBD and South East Light Rail, Sydney Metro and Parramatta Light Rail. Together with investment in our roads, these projects provide an integrated solution for Tomorrow’s Sydney, enabling urban transformation and crucial public transport options.

The NSW Government is investing more than $770 million in the Transport Access Program to deliver accessible, modern, secure and integrated transport infrastructure where it is needed most. This includes station upgrades, better interchanges and park and ride facilities as well as upgrades of ferry wharves that provide improved access to people with a disability, older people and parents with prams.

Sydney Gateway

Sydney Airport and Port Botany are critical international gateways helping to move people and goods around New South Wales. They are set to grow significantly over the next 20 years. Supporting this growth requires efficient connections to the city and Sydney’s other major centres and freight terminals. Part of the solution is Sydney Gateway. Sydney Gateway will provide a new alternative route to enhance connections and reduce travel times to Sydney’s ports. It will provide improved access to all airport terminals and cater for increased rail freight, which will help take pressure off local roads.

Sydney Airport road upgrades

The NSW Government is upgrading roads around Sydney’s Kingsford Smith Airport to help improve traffic flow around the airport and Port Botany. The upgrades will also complement Sydney Airport’s upgrades to the internal road network and the provision of a new link to the precinct via Sydney Gateway.

Western Harbour Tunnel and BeachesLink

Roads and Maritime Services is carrying out planning and development activities to inform a final Business Case for the Western Harbour Tunnel and BeachesLink. This proposal would deliver another Sydney Harbour road crossing and link WestConnex at Rozelle with the Gore Hill or Warringah freeways. It would also provide a connection to Sydney's northern beaches.

F6 Extension

Roads and Maritime Services is investigating options to connect the M1 Princes Motorway at Waterfall with the Sydney motorway network. The proposed project would generally follow the long-standing F6 road reservation, greatly improving travel times in the St George area, Sutherland Shire, Illawarra and South Coast. WestConnex will deliver an underground connection at Arncliffe for this planned motorway as part of the New M5 project.

Rozelle Rail Yards site management work

The former Rozelle Rail Yards site was overgrown and derelict from years of disuse. The site has not been operational for more than 20 years and was well overdue for a clean-up. The NSW Government has undertaken a range of activities on the site, to help address these issues. These activities will facilitate use of the site for the WestConnex M4-M5 Link Rozelle Interchange project.

M4 Smart Motorway project

The M4 Smart Motorway project will introduce intelligent technology, known as a Smart Motorway system, to Sydney’s M4 west of WestConnex – between Pitt Street, Mays Hill and Russell Street, Lapstone. The Smart Motorway technology will also be applied to WestConnex. The M4 Smart Motorway project is being delivered by Roads and Maritime Services.

The Bays Precinct Urban Transformation Program

A Plan for Growing Sydney identifies the revitalisation of The Bays Precinct in Sydney Harbour as a key priority. UrbanGrowth NSW is managing the transformation of this area – containing 95 hectares of land and 94 hectares of waterways. The former Rozelle Rail Yards in The Bays Precinct have the potential to reconnect areas to the north and south of the Rail Yards, and to improve connections from Lilyfield to the harbour.. The Rozelle Interchange, part of the WestConnex M4–M5 Link, will be located within the Rozelle Rail Yards site as will future CBD and South East Light Rail stabling.

Parramatta Road Corridor Urban Transformation Strategy

The Parramatta Road Corridor Urban Transformation Strategy responds to two broad needs identified in A Plan for Growing Sydney – to support growth, and make the corridor a better place to live, work and visit. Traffic volumes along Parramatta Road have increased commensurate with the growth of the city. Close to 100,000 vehicles (including up to 8000 trucks on some sections) pass along the road each weekday, and many parts of Parramatta Road suffer from dilapidated shop fronts and a lack of activation generally. WestConnex will support the planned urban renewal and regeneration along the Parramatta Road by taking heavy vehicle traffic off surface roads including Parramatta Road, into the new underground motorway tunnels. As part of the WestConnex project, $200 million has been allocated to UrbanGrowth NSW to commence its urban renewal program for Parramatta Road. The delivery of WestConnex and other key infrastructure, including social infrastructure, will support the population and economic growth of the corridor over the coming decade and help to enable ongoing economic prosperity for the Greater Parramatta.

Alexandria to Moore Park Connectivity Upgrade

The NSW Government is investigating key intersection improvements to reduce travel time, improve connectivity and support urban renewal on the southern outskirts of the CBD.  The Alexandria to Moore Park Connectivity Upgrade includes network improvements in Alexandria, Waterloo and Moore Park. The project will connect at Euston Road to the local road upgrades being delivered in Alexandria as part of WestConnex New M5.

Parramatta Light Rail

In December 2015, the NSW government announced that Parramatta Light Rail would be the centrepiece of an improved transport network serving Greater Parramatta. It would connect the key growth precincts of Westmead, Parramatta and Camellia, with Carlingford, Sydney Olympic Park and Strathfield. The new light rail will provide a new public transport option for these communities and will work alongside WestConnex to better connect key employment and residential hubs throughout Parramatta.

The Pinch Point Program

‘Pinch points’ are bottlenecks in the road network that result in traffic congestion and travel delays. Roads and Maritime Services runs the Pinch Point Program to address these bottlenecks, so as to reduce delays, manage congestion, improve safety and maintain reliable travel times – particularly during weekday peak periods. These minor network improvements will support WestConnex in easing congestion across Greater Sydney.

Hill Road westbound off-ramp

Roads and Maritime Services is proposing to build a westbound off ramp from the M4 Motorway to Hill Road at Lidcombe. The proposed westbound off ramp would improve connectivity for existing residents in Newington and Wentworth Point and support development growth in the future Carter Street Urban Priority Precinct estimated to generate 5,500 new homes and 5,500 new jobs.

Bus Priority Program

Transport for NSW and Roads and Maritime Services are working together to improve bus services across the city and deliver on the Sydney’s Bus Future plan. This includes priority routes along Parramatta Road. WestConnex enables better bus services on Parramatta Road by reducing traffic on this corridor.

Sydney Metro City and Southwest

A new 30-kilometre metro line will extend from the end of Sydney Metro Northwest at Chatswood under Sydney Harbour, through new CBD stations and south-west to Bankstown. It is due to open in 2024 with the capacity to run a metro train every two minutes each way. Sydney Metro City and Southwest passes in underground tunnels below Marrickville and St Peters and a construction compound for the project will be next to the New M5 project area.
