The Victorian Government's Western Freeway safety package is now complete, following the installation of a 230 kilometre flexible safety barrier.
The Western Australian Government has allocated $25.78 million to upgrade the state's worst roads, through the State Black Spot Program.
In a first for the state, Main Roads Western Australia will trial a roller safety barrier on a Murdoch Drive Connection ramp connecting Roe Highway to Kwinana Freeway northbound.
Construction will soon begin on new intersection upgrades on the Calder Highway, with the aim of reducing accidents and improving freight efficiency in north-west Victoria.
The speed signs are triggered by sensors that detect cars approaching on the side road, temporarily reducing the speed on the highway.
Australia Post has announced a four-year partnership with the Australian Trucking Association with a focus on road safety.
