Redcliffe Road (Anzac Avenue), Gympie Road and Dayboro Road (Petrie), improve intersection

The Petrie roundabout, a major intersection providing an important connection between the suburbs of Moreton Bay region and wider transport networks, has been upgraded.

The roundabout experienced high congestion during morning and afternoon peak periods, causing significant queuing and travel delays.

Traffic demands for this intersection are growing, with significant regional and local developments such as the University of Sunshine Coast campus and ‘The Mill at Moreton Bay’, accelerating the need for greater road capacity.

The upgrade installed a signalised T-intersection with wider approaches to help ease congestion, reduce travel time for motorists and improve safety for all road users. It also improves connectivity between key employment, industrial, educational and residential areas in the Moreton Bay region.
