A range of upgrades have been announced for Melbourne’s road and public transport networks.

Almost 4,000 new train, tram and bus services per week will be added to the public transport schedule, at the same time as a major section of the multi-billion-dollar East West Link is approved.

Victorian Transport Minister Terry Mulder said new services target the most overcrowded lines.

“We are shortening up those breaks between trains, but we are looking at the areas where we know the overcrowding is occurring and where we know we're going to get massive growth,” Mr Mulder told ABC Radio.

New runs will see 3,260 extra bus services, 470 new tram services (including an entirely new line) and over 200 more trains at peak times.

Victoria's Public Transport Association says the enhancements are “small steps” toward a better system, but “huge investment in public transport improvement” will be needed soon.

Meanwhile, Victoria's Planning Minister Matthew Guy has given final approval to the eastern section of Melbourne's East West Link.

About a hundred properties will be compulsorily acquired for the six-kilometre stretch of road, which has been reformed slightly on the recommendations of an independent committee.

Proposed interchanges, flyovers and other connections have been adjusted, and the project's committee - the Linking Melbourne Authority – is expected to submit a modified plan to the Government in coming days.

There has been speculation that more properties will need to be compulsorily acquired for the project, but there has been no official word beyond original estimates.
