Mr Rann will today announce $12 million funding for new bike paths along rail corridors and waterways.
Modelled on the Linear Park, Coast Park and Mike Turtur Bikeways (formerly Tramway Park), the cycling and walking paths will be known as "Greenways".
"The number of people riding into the CBD on a daily basis has also increased from 5011 in 2003 to 7744 in 2009 - an increase of just over 50 per cent," Mr Rann said.
"Our long-term plan is to create a linking network of cycling and walking paths that stretch across the metropolitan area.
"The first priority will be a 15km Greenway from Adelaide to Marino Rocks . . . along the electrified Noarlunga rail line."
Other bike paths listed on the map, including the Sturt River and Little Para River already exist.
