Improving our networks

Transurban now manages fourteen toll road assets, and it is crucial that we keep these roads in good working order and improve them to meet the changing needs of our cities.

In FY15, we completed or initiated a number of upgrade works on our existing assets.

CityLink-Tulla widening

In April 2015 Transurban signed a revised agreement with the Victorian Government to deliver the CityLink Tulla Widening (CTW) project. Transurban will deliver upgrades from Bulla Road to Power Street, while the State Government will undertake works beyond Bulla Road.

In total, the project will see additional lanes and other measures to improve traffic flow across 24 kilometres of freeway between the CityLink tunnels and Melbourne Airport. It will increase capacity, reduce peak period travel times and boost safety along one of the city’s busiest and most important toad corridors.

The project will transform this part of Melbourne’s network and alleviate significant pressure points, supporting the rapidly growing suburbs in Melbourne’s north and west as well as improving travel time reliability for vehicles using CityLink’s Western Link, which accommodates around 210,000 vehicles per day in its busiest section.

Additional lanes will provide a 30 per cent increase in capacity to improve safety and ease congestion, creating a more reliable journey and consistent travel times. On average drivers will save 16 minutes in the morning peak and 17 minutes in the afternoon peak.

The CTW project is using the ISCA rating scheme and targeting an ISCA ‘Excellent’ rating to reflect a range of initiatives being assessed in the planning, design, construction and operation of the project.

Extensive community engagement was undertaken during planning for the project and continues as works approach. Most recently inJuly and August 2015, a series of community information sessions took place along the CTW project corridor to provide community members with the latest information about the project, including scope and milestones.

The sessions offered the community the chance to view information, provide feedback and speak to the project team who were on hand from Transurban, Vic Roads and Leighton Contractors. Each session had the detailed section maps and key interchanges on display, along with animations of the project and the Freeway Management System.

There will be further opportunities for local residents, businesses and other stakeholders to find out more about the project and its progress with updates via the website, information flyers and face-to-face meetings.

Major construction is planned to start in October 2015 and expected to finish in early 2018.

Fact sheets and videos about the project are available on the project website here.

M5 West widening

In December 2014, we completed the M5 West widening project in New South Wales.

The project added an extra lane in each direction to a 22 km section of the M5 motorway and marks a significant milestone in the ongoing development of the Sydney orbital network.

The project increased motorway capacity by 50 per cent and benefitted the 125,000 motorists who use it every day by reducing travel times by up to 25 per cent in the morning and evening peak periods.

It also improved the communication between our traffic controllers and customers with a new control centre at Hammondville. With the installation of a new CCTV system and additional variable message signs, the project also improved customer safety and incident response times.

The $400 million project was finished on time and on budget and supports south-west Sydney’s planned residential and employment growth.

Eastern Distributor re-sheeting

The Eastern Distributor re-sheet project was completed in May 2015. The 15-month planned maintenance activity involved resurfacing the motorway with new safer and more reliable pavement.

A total of 95,000 man hours went into the successful delivery of this project, which was completed ahead of schedule.

The re-sheeting work on the Cleveland Street Underpass involved a new method to resurface the area with hydraulic pumps being used to lower the water table immediately below the base of the roadway, which was then dried with specialist equipment before the new asphalt was laid.

Transurban and Downer Infrastructure were awarded the Most Outstanding Project for their work on the Cleveland Street Underpass during the re-sheeting. The award celebrates quality roads and pavement engineering excellence.
