Petrie Intersection Upgrade

Project Overview

The intersection is an important connection between the suburbs of the Moreton Bay Region, and wider transport networks.

The complex roadworks project was constructed in a constrained and highly trafficked urban environment.  The Petrie Intersection 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. The upgraded infrastructure also improves connectivity between key em­ployment, industrial, educational, and residential areas in the Moreton Bay region.

Ertech worked collaboratively with the Client’s project representatives and designers to overcome design-related project challenges. The project team performed well to meet key milestones and deliver high-quality project outcomes despite significant impacts from COVID and major weather events.
