Two applications have been submitted to Barnsley Metropolitan Borough Council outlining plans to bring together the town's bus and rail stations in a transport interchange designed by architects Jefferson Sheards.
The applications contain two designs that differ only in their scale.
The larger scheme would progress if the council manages to persuade the Department for Transport to step up its contribution beyond the £16.8 million already promised.
The proposal would increase the interchange capacity and improve the local road system to offer pedestrians improved walking routes around the interchange. There are also proposals for a footbridge connecting the interchange with other key town centre sites.
Plans to redevelop Barnsley's market and Metropolitan Centre have also been unveiled by the council. A masterplan has been produced for the site along with a brief, which will be used to attract a development partner.
The project, a joint venture between the council and regional development agency Yorkshire Forward, proposes a 21st century market that would be the heart of the town centre.
Remaking Barnsley is a 30-year vision for the town drawn up by Alsop Architects under Yorkshire Forward's Renaissance Towns initiative.
