The new section of the North-South Motorway has now increased to 80km/h.


The Regency Road to Pym Street (R2P) Project has been carefully designed to maintain existing vegetation wherever possible.

The R2P Alliance has developed a landscaping package with a focus on:

  • vegetation replacement - planting 700 new trees, grasses, ground covers and shrubs to offset the removal of trees;
  • green infrastructure – an emphasis on making a green corridor and providing generous amounts of landscaping and trees for aesthetics and shading;
  • landscape design - use of indigenous with non-indigenous species and inclusion of semi-mature trees to help offset the loss of mature vegetation. Forty five species of grasses, groundcovers and shrubs will be used;
  • butterfly attracting vegetation - butterfly gardens to tie in with the Community Wildlife Project. For more information click here to read the Community Wildlife Fact Sheet and view maps below;
  • longevity - installation of irrigation will assist with growth; and
  • environmental guidelines - species selection adheres to safety standards for proximity to the North-South Motorway.

Landscaping map - proposed landscaping, south of Regency Road

Landscaping commenced in July 2020, with the construction of footpaths, Shared Use Paths and compacted rubble verges, installation of irrigation, laying of turf and preparation of garden beds for planting. Garden vegetation and tree planting will commence in late 2020, and is expected to be complete by mid-2021, weather permitting.

Landscaping will take place along:

  • South Road between Overland Road and Aruma Street (eastern side);
  • South Road between Tait Street and the Regency Park Golf Course (western side);
  • Regency Road between Naweena Road and Crossley Avenue (southern side);
  • Regency Road between Naweena Road and the TAFE SA Regency Campus (northern side); and
  • the intersection of South Road and Regency Road.

Plant and tree species

Enhancing amenity and habitat is an important objective of the R2P Project that is considered throughout the species selection process. The Department for Infrastructure and Transport, The Office for Design and Architecture South Australia (ODASA) and the City of Port Adelaide Enfield reviewed and approved the species selection.

The species selection is based on the following factors:

  • hearty and requires minimal maintenance;
  • native to the area;
  • drought tolerant;
  • contributes to local biodiversity; and
  • variety of leaf textures for visual amenity.

Upon approval of the species selection, the R2P Project commenced the growing and sourcing process.

Shrubs, groundcovers and grasses are propagated and take approximately six to nine months to reach the required size of up to 10cm tall (approximately 140 litre pot).

Trees are sourced from local growers who have pre-grown the species for up two years to reach the required size of up to 1.2 metres tall (approximately 45 litre pot).

When complete, landscaping will span over 29,000 square metres and comprise of:

  • 43,603 plants including 16 species of shrubs and 19 species of groundcovers; and
  • 512 trees including 10 deciduous and native species.

Plant establishment will vary across the species of plants and trees, however the expected times to reach full maturity are three to five years for shrubs, groundcovers and grasses, and 15 – 20 years for trees.

Growth rates are approximate as natural elements like location, light, water and temperature will factor into their establishment.

Permanent irrigation will be installed in the landscaping. This will support species that are more suitable to residential neighbourhoods.

The following images, taken by the landscape contractor and grower who are providing the stock, show plants being grown at the nursery ready for planting, showing the size of the plants and trees at time of planting.
