The South Road Superway project in South Australia is a major investment to upgrade a key road corridor. The project includes a 2.8km elevated roadway with innovative design features like curved piers and a balanced cantilever superstructure. By using needle beams for mid-span articulation, the need for large bearings under the deck was reduced, lowering future maintenance requirements. The project aimed to create a durable and low-maintenance structure while considering variations in exposure conditions across the site.
