A 110m-long bridge with steel mesh ballustrading will span the entrance of the Elizabeth Quay inlet.
The design for the $20 million Elizabeth Quay pedestrian bridge has been released by the State Government.
The structure connecting the inlet island and the foreshore will feature two large arches and be constructed using steel and wood.
The island is already being constructed and dredging of the 2.7ha inlet will start next week.
Planning Minister John Day said the bridge would be an important link between the cafes and bars on the promenades, the island and the new ferry terminal.
The bridge will rise about 5.2m from the water surface and allow moderate-sized boats into the inlet.
“The bridge will be generous enough for cyclists and pedestrians, sit high enough above the water for most boats to pass underneath and will incorporate feature lighting to add to the ambiance of the quay at night,” Mr Day said.
When complete, the $440 million Elizabeth Quay project will provide a place of work for 10,000 people and have a residential population of 1400.
More than four million visitors are expected to visit the area annually.
