MARION - RICHMOND ROADS INTERSECTION UPGRADE

LOCATION Richmond, SA
CLIENT Department for Infrastructure and Transport
DESCRIPTION Major Intersection Upgrade
PROJECT PERIOD 2023-2024
PROJECT VALUE $40M

The Marion Road and Richmond Road intersection upgrade was part of the North-South Corridor: Broader Network Upgrades, supporting the River Torrens to Darlington Project. The goal was to increase city-bound traffic capacity, improve vehicle and freight access, and enhance connectivity to the Adelaide CBD and Adelaide Airport. The upgrade also aimed to improve intersection efficiency and overall capacity.

MLEI was the principal design lead for civil design and documentation. Our scope included:
• Civil engineering detailed design
• Pavement design, traffic signal design, lighting design, urban and landscape design
• Cost estimation
• Constructability assessment
• Traffic engineering
• Environment, heritage and sustainability.

Upon being awarded the contract in October 2023, the MLEI Civil Team, alongside our subcontractors, quickly commenced work, achieving 30% project completion. Among the three intersections involved in the North-South Corridor upgrades, MLEI was recognised by DIT as the best-performing and most consistent project manager. Unfortunately, due to factors beyond our control—primarily the withdrawal of Federal Government funding—the project was halted in April 2024.
