The West Gate Freeway is a major freeway in Melbourne, the busiest urban freeway and the busiest road in Australia^{[citation needed]}, carrying upwards of 200,000 vehicles per day. It links Geelong (via the Princes Freeway) and Melbourne's western suburbs to central Melbourne and beyond. It is also a link between Melbourne and the west and linking industrial and residential areas west of the Yarra River with the city and port areas. The West Gate Bridge is a part of the freeway.

It is a fully managed freeway with a complete 'Freeway Management System' that is dynamically linked and adaptive to the entire M1 corridor. This includes the 2008 re-design of a substantial section. Overall, the freeway has between 4-6 lanes in each direction, with a maximum of 12 lanes at one point in its width.
