Infrastructure projects at Melbourne's sporting events precinct will help the city regain its title as sporting capital of the world, the state government says.

Ahead of the Australian Open starting on Monday, Sports Minister John Eren has revealed plans for a new pedestrian bridge connecting the Melbourne Park tennis precinct with the CBD.

Stage two developments of the project are worth $338 million and will also include a new eight-storey administration and media building.

“Unfortunately we’ve lost our title as sporting capital of the world to London back in 2012 and I intend to get that back,” he told reporters at the redeveloped Margaret Court Arena.

“There are a number of things we need to do to get it back, and that’s investing in infrastructure.”

The new Batman Avenue Bridge will run from Birrarung Marr’s lower terrace to a new grass hillside amphitheatre area alongside show court two, with a deviation to Speaker’s Corner.

Construction work on the new building will begin later this year, with work on the bridge to start in 2016.
