Australia’s Government has completed a A$116m ($121m) project to upgrade and widen a section of the F5 Freeway, between Brooks and Narellan in New South Wales.

Completion of the project will provide quicker, less frustrating journeys to residents of Campbelltown and Sydney’s south-west, who commute along the F5 Freeway.

Australian Infrastructure and Transport Minister Anthony Albanese said the upgrade complements earlier widening work between Camden Valley Way and Brooks Road and is already delivering real benefits for 80,000 motorists and truck drivers which use the F5 daily.

"Equally, the money we’ve invested will go a long way to making sure this vital part of the city’s road network is able to cope with future demands," Albanese said.

The project was completed in three stages and work on the project involved widening the freeway from four to eight lanes between Raby and Brooks roads, then to six lanes from Raby Road to Narellan Road.

First stage of the project involved widening of the freeway to four lanes in each direction between Brooks Road and St Andrews Road. Work on this section commenced in February 2009 and was completed by June 2011. The second stage of the project involved widening to four lanes in each direction between St Andrews Road and Raby Road, which started in June 2009 and finished in December 2011.

Stage three of the project involved widening to three lanes, in each direction, between Raby Road and Narellan Road, which commenced in September 2010.

NSW Roads Minister Duncan Gay said those sections of freeway were re-surfaced and a new on-ramp built to make it easier and safer for motorists coming along Raby Road to join the F5.

"As part of the forward thinking and planning that went into this project, the builders took the opportunity to install the sensors and cabling which will form the backbone of a future electronic management system, new technology which can prevent congestion and give motorists real-time traffic information," Gay said.

Australia’s Government contributed A$93m ($97m) while NSW contributed A$23m ($24m) to the project.
