The Brisbane City Council has grave concerns for the proposed pathway on the new Queen's Wharf.
The proposed design will stretch over 890 metres and will have a separate path run for 570 metres, while 250 metres will be a shared cycling and pedestrian pathway.
The remaining 70 metres will be a mixed-used plaza similar to King George Square.
A council officer said the council had contacted the state government several times raising concerns about the design and suggested the path should be separated.
