Northern Expressway - South Australia

South Australia's largest road landscaping project involved the design and construction of 23kms of a four lane divided expressway linking Adelaide's northern suburbs.  The landscaping included the propagation and planting of 750,000 indigenous tube stock, 160ha of native and exotic grassing, wetland establishment and waterway re-instatement and preparation of 350,000sqm of garden beds. 

The project construction was completed in 2010 followed by a three-year maintenance and defects liability period. The project has set the standard of what can be achieved in a roadside landscape in South Australia.

Testament to our ability to undertake large-scale landscape maintenance, we are now employed directly by the Department of Planning, Transport and Infrastructure to maintain the project on an ongoing basis with the new challenge of responding to work on short notice with the aim to achieving suitable landscape maintenance on a tight budget.

Through this project, Ecodynamics has consolidated its knowledge of northern provenance native plants and grasses and developed a strong understanding of efficient and sensitive weed control techniques for the northern Adelaide region.  Native grasses were successfully established and have been maintained by Ecodynamics with a specialised mowing program. 

The project has demonstrated Ecodynamics' ability to deliver and maintain large scale landscapes to a high quality in tight timelines by working closely with the contractor and developing design innovations and cost savings.
