The Socialist Party has a history of involvement in the opposition to the East-West Tunnel, a proposed infrastructure project in Melbourne's north that involves building a road tunnel ostensibly to ease congestion. The project has come under substantial criticism from many sources since its inception, and the government has been slow in releasing information on the full nature of the project. The Socialist Party holds the position that the tunnel 'is not about making the lives of ordinary people easier' but is 'about serving the needs of the big transport companies', and they contend that it will not substantially ease traffic congestion, but will divert funds from public transport as well as causing damage to the areas through which the tunnel will be built. They instead support the expansion and improvement of public transport to improve service to Melbourne's outer suburbs and to reduce congestion.
