CityLink is a major transport infrastructure project in Melbourne, Australia. It consists of a network of freeways and tunnels designed to improve traffic flow and reduce congestion in the city. Opened in 2001, CityLink connects key areas, including the Tullamarine Freeway, Monash Freeway, and West Gate Freeway, facilitating easier access for commuters and freight transport. The project was developed by Transurban, a company specializing in toll road management. CityLink operates as a toll road, meaning drivers pay fees to use certain sections. This funding model helps maintain the infrastructure and supports ongoing improvements to the transport network.
