Roystonea Avenue duplication

The Department of Logistics and Infrastructure (DLI) is duplicating Roystonea Avenue in Palmerston, from Terry Drive to Lambrick Avenue, starting in April 2025.

Roystonea Avenue is a key access road connecting Palmerston CBD to the suburbs.

The duplication will:

  • improve road safety, traffic flow and drainage, particularly around the Inverway Circuit intersection
  • address the currently unsignalised Roystonea Avenue and Inverway Circuit intersection, and peak hour delays and congestion
  • cater for the future population growth expected in the area
  • address seasonal localised flooding experienced on the road.

As part of the works, pedestrian crossings will also be added at the Inverway Circuit intersection.

During the project

Access to Inverway Circuit and Buscall Avenue from Roystonea Avenue will be restricted at times during the works, and detours will be in place.

Traffic management will include use of speed reductions and temporary lane closures to ensure the safe and efficient flow of traffic.

There may be some delays to traffic flow from time-to-time during the construction. Road users are encouraged to seek alternative routes where possible.

Motorists are asked to take caution during these works and comply with all traffic management and signage in place.

Current works

Roystonea Avenue

From 4 to 19 November, traffic travelling towards Palmerston city centre will be switched to the permanent inbound side of Roystonea Avenue, while traffic travelling towards Lambrick Avenue will remain on the outbound side.

Traffic management, including single-lane closures in each direction, will be in place while works are completed.

Buscall Avenue temporary closure

As part of the project, an upgraded intersection with dedicated turning lanes have been installed at the Buscall Avenue and Roystonea Avenue intersection.

All turning movements at the Buscall Avenue intersection will be restored, with traffic management in place to support ongoing works.

Terry Drive changed access

From 4 to 11 November, temporary right-turn restrictions will be in place at the Terry Drive intersection. There will be no right turn from Roystonea Avenue onto Terry Drive, and no right turn from Terry Drive onto Roystonea Avenue. Alternative access is via Temple Terrace or Buscall Avenue.

From 12 November, vehicles can turn right from Roystonea Avenue onto Terry Drive, and vehicles can turn left from Terry Drive onto Roystonea Avenue. There will be no right turn from Terry Drive onto Roystonea Avenue.

Inverway Circuit changed access

As part of the changed traffic conditions, vehicles will be permitted to turn left from Inverway Circuit onto Roystonea Avenue.

Vehicles are also able to turn left from Roystonea Avenue onto Inverway Circuit, but there will be no right turn from Roystonea Avenue onto Inverway Circuit and no right turn from Inverway Circuit onto Roystonea Avenue.
