Banora Point Upgrade

Our Role

SMEC provided traffic engineering and design services for roads, structures, drainage works and associated infrastructure as well as geotechnical engineering services, and community engagement.

Project Overview

SMEC partnered with Abigroup and Seymour-Whyte to deliver this complex design and construct project for Roads and Maritime Services. The project involves the upgrade of 2.5 km of the Pacific Highway, a critical transport link between Sydney and Brisbane.

Key features of the project included:

• A six-lane divided carriageway with an improved alignment
• A three-lane 330 m long viaduct
• Four twin overbridges and two single overbridges
• Reshaping adjacent Wilson Park, including provision of a shared pedestrian and bicycle path across a 75 m wide land bridge.

A number of challenges were faced during the life cycle of the project, namely:

• Highly complex traffic management requirements
• Environmental management to minimise noise and vibration, and prevent erosion and sediment loss
• Geotechnical complex main cutting which required both contiguous pile and soil nail retaining walls in the deep cutting.

With over 55,000 vehicles using this stretch of road every day, the completion of the Banora Point Upgrade has improved both efficiency and safety on the Pacific Highway.
