Transport Minister Mark Bailey and lord mayor Adrian Schrinner have put on a united face for the council's $944 million Brisbane Metro mass transit project, after months of sniping over delays to construction.

The minister and lord mayor fronted a joint press conference on Friday afternoon to announce the council had been given the go-ahead for small infrastructure works around South Brisbane for the project.

The relationship between the council and state soured in June when Cr Schrinner attacked the Transport Department for requiring late-term changes to the planned Cultural Centre station, the final location of which is still under investigation by both parties.

The state government asked the council to model moving the station to under the Brisbane Convention and Exhibition Centre: that prompted an angry broadside from Cr Schrinner, who for months after accused Mr Bailey of enacting a go-slow on the project and failing to communicate.
