The Monash Freeway Upgrade will improve safety and reliability along the 44 kilometres between Chadstone and Pakenham, extending what is already Australia's longest stretch of managed motorway. The upgrade is part of the $5.5 billion Western Distributor Project and includes 30 kilometres of extra traffic lanes along with major improvements to the managed motorway system.
