Osburn St has reopened to traffic following works to link the road to the new Havelock St extension.
Traffic lights are still to be installed at the new intersection and the Havelock extension will not open until the lights are active.
The extension of Havelock St completes the inner ring road giving vehicles an alternative route to move around the CBA.
The new road will have a single lane of traffic in each direction, cycle lanes, centre median parking, shared footpaths, street lighting and landscaping.
The project will also include new footpath linkages to connect with new and existing pathways in Hovell St.
The project is part of the National Stronger Regions Funding program and is scheduled for completion in April-May this year.
