CityLink is a network of tollways in Melbourne, Victoria, Australia, linking the Tullamarine, West Gate and Monash Freeways and incorporating Bolte Bridge, Burnley Tunnel and other works. In 1996, Transurban was awarded the contract to augment two existing freeways and construct two new toll roads – labelled the Western and Southern Links – directly linking a number of existing freeways to provide a continuous, high-capacity road route to, and around, the central business district. CityLink uses a free-flow tolling electronic toll collection system, called e-TAG. CityLink is currently maintained by Lendlease Services.

The Eastern Freeway is an urban freeway in eastern Melbourne, the state capital of Victoria, Australia. It is one of the most important freeways in terms of commuting to the city, connecting Alexandra Parade and Hoddle Street in the inner suburbs, with EastLink tollway farther east. It consists of between three and six lanes in each direction, also an inbound transit lane reserved for vehicles with two or more occupants during peak hours.
