Monash Freeway Upgrade

More lanes for the Monash

Community Update, August 2017 


Major works to ensure safer and more reliable journeys on the Monash Freeway are progressing well.

Around 5 kilometres of asphalt have already been laid for new lanes in the centre of the road. Temporary safety barriers have now been removed around these sections, so that work can progress along other areas of the project.

Although the new lanes may appear almost ready to use in these sections, there are still final works to be done before they can be opened to traffic. Yellow lines and reduced speed limits of 80km/h will remain in these areas until the new lanes are opened.

Works to widen road bridges are also progressing, with more than 1,300 cubic metres – almost 3,200 tonnes – of concrete poured to date to form decks for new lanes on the bridges at South Gippsland Freeway, Magid Drive and Narre Warren Main Drain.

Smart technology to keep you moving

As part of the Monash Freeway Upgrade, new and upgraded ramp signals and variable message signs will be installed from Chadstone to Pakenham. This will help prevent traffic banking up and causing congestion and crashes.

When traffic incidents occur, this smart technology will give drivers advanced notice of lane closures and variable speed limits to help keep everyone moving.

To build this new Freeway Management System, works to lay cables that will power new electronic signs are underway along the side of the Freeway. Crews have already installed almost 13 kilometres of cables to date.

Bridge beams lifted for extra lanes

Bridge beams have now been installed at all of the eight bridges being widened as part of the project. In total, 52 beams weighing up to around 82 tonnes each have been lifted into place at the South Gippsland Freeway bridge, Magid Drive bridge, Pakenham rail bridge, Narre Warren Main Drain, Eumemmerring Creek, Dandenong Creek and Troups Creek East and Troups Creek West.

These works involve digging deep holes into the ground for new support pillars on each side of the bridges, ahead of work crews lifting the large beams into place. A thick slab of concrete is then poured to strengthen and connect the new and existing sections into one large bridge.

While the concrete sets, it’s vital to keep vibration to a minimum so we need to reduce speed limits around the bridges. So while it may look like there are no works taking place, the concrete is setting to attain its needed strength. The next of these concrete pours will take place at Eumemmerring Creek Bridge in mid-August.

Driving down our environmental footprint

The Monash Freeway is being upgraded using materials that are environmentally friendly and sustainable wherever possible. Throughout the project, the team has used ‘Greenpipes’, which are plastic pipes made from 100 per cent recycled materials.

Greenpipe has been used along the Freeway to reduce green-house gas emissions, and to also support the waste recycling industry. All pipes are manufactured in Australia and developed using a unique low energy process undertaken by Recycled Plastic Technology Pty Ltd.
