One of Brisbane's city leaders has been warned to "get out of the way" and not hold up a $115 million road project nine years in the making.

The Wynnum Road corridor upgrade was first announced by Brisbane City Council in 2014 following a lengthy push for a road upgrade from councillor Shayne Sutton (Morningside).

The early stages of the project had commenced and were received overwhelming support from both LNP and ALP councillors, but the council's first and only Greens councillor Jonathan Sri (The Gabba) was threatening to stop, or at least delay, the project, which he believed was a "mistake" and a "poor use of ratepayer funds".

On Tuesday the details of the contracting plan for Stage 1 and Stage 1B of the project were discussed at council chambers ahead of the tender opportunity being opened to south-east Queensland contractors in the coming weeks.
