What is the purpose of the Golden Grove Road Upgrade?

Golden Grove Road is a key arterial road in the north-eastern suburbs providing an important link in the metropolitan road network. It intersects with a number of other key arterial roads and local roads. The road has one lane in each direction, and traverses urban and semi-urban land. The stretch of road is a major commuter route for the expanding residential area of the north-eastern suburbs.

This upgrade of Golden Grove Road will help ease traffic congestion as well as improve safety for all road users. The upgrade forms part of the Department for Infrastructure and Transport's (the Department) commitment to continually develop and upgrade the key arterial road network.

The Golden Grove Road Upgrade Project will be delivered in two stages:

Stage One – One Tree Hill Road to the north side (Kunzea Way) of the signalised intersection of Golden Grove Road/The Grove Way/Yatala Vale Road.

Stage Two – Park Lake Drive to the north side of the signalised intersection of Golden Grove Road/The Grove Way/Yatala Vale Road.

When will construction commence and be completed?

The upgrade of the 3.4km section of Golden Grove Road between One Tree Hill Road and Park Lake Drive, is being undertaken in two stages.

Stage One 

Early service relocation works commenced in September 2019. Main construction works commenced in December 2019, and were completed in late 2020.

Stage Two

Construction on Stage Two is underway, and roads are expected to be open to traffic by late 2021, weather permitting.

What construction impacts might be experienced?

During the project, the community may experience a number of construction impacts including noise, dust, vibration, light spill (from light towers), and change to access and traffic delays. A Construction Environmental Management Plan (CEMP) will be developed outlining the measures that will be implemented to mitigate impacts, as much as practically possible.

How will traffic be managed during construction?

Early service relocation works and main construction works will be coordinated to minimise impacts, as much as practically possible, and to balance the needs of all road users including motorists, pedestrians, cyclists, as well as residents and businesses.

Signage, Variable Message Signs (VMS) and traffic management will direct traffic through and around roadwork areas. Road users are advised to take extra care when workers are on site and observe any speed and lane restrictions when travelling through the area.

Will there be night works?

Project works are primarily scheduled to occur during the day. However, some night works will be undertaken to minimise impacts on road users and allow works to be completed safely and efficiently. Local residents will be notified in advance of night works and impacts will be minimised, as much as practically possible.

How will access to properties be managed during construction?

The project will make every effort to minimise impacts on property access. Should a property be temporarily impacted, property owners will be notified in advance and alternative arrangements put in place.

How will noise be managed during construction?

Construction noise is unavoidable. However, as well as providing advance notices of works, a number of practicable measures will also be taken to minimise noise levels including:

  • scheduling the noisiest construction activities during the day or early evening, where possible;
  • using low noise reversing squawkers in preference to traditional reversing beepers, where possible; and
  • maintaining low speed limits for construction trucks and machinery.

How will dust be managed during construction?

While dust cannot be completely eliminated, every effort will be made to minimise dust impacts during the works. This will include:

  • implementing speed restrictions on unsealed surfaces;
  • watering down work areas;
  • installing rubble at entry and exit points into the project area;
  • removing excess material on trucks and machinery before exiting the construction area;
  • covering transported materials; and
  • regular use of street sweepers.

How will vibration be managed during works?

During construction, some vibration from machinery is unavoidable. However, experiencing vibration does not mean structural damage to properties will occur and the works required for this project are not expected to result in structural damage to any properties.

To help minimise the effect of construction vibration, a range of measures will be implemented including:

  • operating equipment on the lowest effective vibration setting;
  • implementing speed restrictions for construction trucks and machinery;
  • maintaining equipment to minimise vibration; and
  • placing vibration monitoring equipment in strategic locations to monitor vibration levels to ensure they do not exceed compliance levels.

Will vegetation need to be removed?

Minimising impacts to vegetation has been considered throughout the design development and where feasible, impacts have been avoided. However, project works will require the removal of vegetation and trees. All vegetation removal will be offset via a contribution to the City of Tea Tree Gully’s revegetation program.

Prior to vegetation/tree removal, inspections will be undertaken to ensure that any fauna present are appropriately removed and relocated to a suitable habitat if possible.

The project team will work closely with the Contractor, relevant authorities, Council and interested parties to minimise and manage impacts to vegetation and wildlife.

A Vegetation Fact Sheet with further details is available on the project website.

Will bus services be affected?

Bus routes will be maintained for the duration of works. However, some bus stops may need to be relocated or temporarily closed.

Advance notice of relocations or closures will be provided to bus users via signs at affected bus stops and on the Adelaide Metro website.

What is the North East Public Transport Study?

The State Government is investing significantly in a stronger public transport network and is committed to delivering increased connectivity, faster and more reliable travel and increased public transport use.

The North East Public Transport Study was undertaken by the Public Transport Project Alliance, including partner organisations McConnell Dowell, Mott MacDonald and ARUP, who were selected to join with the Department for Infrastructure and Transport to investigate possible outcomes.

The study identified the need for improvements to O-Bahn bus services in the area and determined that intersection upgrades with dedicated bus ‘jump lanes’ were the preferred option and will reduce travel time for commuters.

An O-Bahn Extension Feasibility Study was conducted to undertake detailed planning work to consider better public transport outcomes for the north-eastern suburbs including Golden Grove, Wynn Vale, Redwood Park, Surrey Downs, Modbury Heights, and Ridgehaven and surrounds.

A summary report on O-Bahn extension options has been released.

Along with stage two, intersections along the O-Bahn route will also be upgraded allowing buses faster access from Tea Tree Plaza to Golden Grove and quicker accessibility for residents wanting to use the service.
