Project overview

ecoDynamics was engaged by the Fleurieu Connections Alliance to deliver the landscaping works for the South Australian and Australian governments’ Main South Road Duplication (Stage 1) and Victor Harbor Road duplication— key infrastructure upgrades improving safety and connectivity across the Fleurieu Peninsula.

With a strong track record in high-profile road and civil infrastructure projects, ecoDynamics was selected for its proven expertise, integrated service delivery, and in-house nursery capability — allowing the team to source and supply locally grown native plant material and seed stock to meet stringent environmental and quality requirements.

Project highlights

Delivering these projects required precise coordination and flexibility, with all works completed behind barriers alongside a live, high-traffic roadway. The early opening of new traffic lanes meant that large portions of the project had to be completed under traffic management and night-shift conditions, demanding careful planning and seamless teamwork.

A standout feature of the Main South Road and the Victor Harbor Road duplication projects  was the inclusion of two rest areas along the Shared Use Paths (SUP), each designed to celebrate and reflect First Nations cultural heritage. These spaces not only enhance the user experience but also contribute to the cultural and community significance of the project.

Scope of works

ecoDynamics was responsible for the supply and installation of all landscaping treatments and SUP rest nodes across 14km of dual-lane, dual-carriageway road for stage 1 of the Main South Road duplication.

Key quantities delivered across both projects included:

• 237,053 plants supplied by the ecoDynamics Penfield Nursery
• 91,000m² of hardwood mulch installed across planting beds
• 7,300m² of jute matting installed within swales and basins
• 220,300m² of hydro-mulched dryland grasses
• 37,700m² of hydro-mulched stabilised batters using Flexterra with native seed mix
• 356,299m² of landscape treatments under a 24-month maintenance program (through to September 2026)

These figures reflect the scale, precision, and environmental responsibility at the heart of the  delivery of both projects.

Challenges & achievements

In the final four months of the projects, ecoDynamics led a team of 16 to complete all close-out works across day and night shifts, ensuring handover was achieved on time in September 2024.

• Over 50 open lots were closed out in collaboration with head contractor engineers.
• All defects resolved.

This achievement underscores the team’s commitment to quality, safety, and collaboration — a hallmark of ecoDynamics’ delivery approach.

Environmental & community outcomes

The Main South Road Duplication Project crossed Pedler Creek Bridge, a high-profile waterway with rich historical and cultural significance, requiring sensitive environmental management.

ecoDynamics also partnered with the local community to host a planting day at Griffiths Basin, fostering engagement and environmental stewardship within the region.

Recognition & legacy

Several ecoDynamics team members received safety and quality recognition awards from the head client for their performance on site — highlighting the professionalism and culture of excellence that underpin every project.

Learnings from Stage 1 have been instrumental in refining the approach for Stage 2, particularly around productivity, access management, and traffic control efficiency — strengthening future delivery outcomes.

Ongoing maintenance

A dedicated four-person crew continues to carry out monthly maintenance visits, ensuring the long-term health, presentation, and sustainability of the landscape treatments.
