Investigator Avenue

The $3.6 million, Investigator Avenue road widening project, begun in January 2020 and includes the widening of the road to 10 metres, construction of concrete kerbing, a 1.5-metre-wide concrete footpath, stormwater pits and underground pipes, rebuilding the affected driveways, planting new street trees and turf and installing LED streetlights to light the new footpath between Nautilus Drive and Queen Elizabeth Drive, Cooloola Cove.  

We thank you for your cooperation while we work to make Investigator Avenue beautiful, safe and user friendly. The project is 50 per cent funded by the State through the Transport Infrastructure Development Scheme (TIDS) program.

Questions and Answers

When is construction work commencing?

Construction work is planned to commence in February 2020 and will take approximately six months depending on weather.

What is happening?

The proposed works include:

  • Road widening including concrete kerb;
  • Concrete footpath;
  • Stormwater pits and underground pipes;
  • Driveway reinstatement at select locations;
  • Planting of trees and turf;
  • Installation of street lights to existing power poles above new footpath.

What are the impacts on local traffic in the area throughout construction?

Temporary lane closures will be in place during construction. Traffic will be able to travel in both directions under stop / slow traffic controllers or signals.  

Will access to residences be affected?

Yes. However, the site foreman will speak with residents on how to access properties when work commences.

Will there be any noise impacts throughout construction?

Yes. The works will require the use of various machinery such as excavators, profilers, bob cats, rollers and truck as well as hand tools such as jack hammers, power saws. Noise from the works can generally be expected between 6:30am and 4:30pm on weekdays.

Will you receive updated notifications throughout the project?

Yes. Project updates will be given to affected residents monthly.  A project update via social media and the project web page will also occur every month during construction.

What is the cost of the project?

This project has been 50 per cent funded by the Queensland Government’s Transport Infrastructure Development Scheme (TIDS). The total budget for the project is $3.6M.

Will the rest of Investigator Avenue from Endeavour Drive to Nautilus Drive be upgraded with kerb and channel?

No, not as part of this project. Council will consider further works on Investigator Avenue in the future along with other funding needs throughout the region.

Will the permanent speed limit on Investigator Avenue be altered following the works?

No. The speed limit will remain at 60km/hr.

Is Council going to build a footpath along Investigator Avenue?

Yes. A 1.5m wide concrete footpath from Nautilus Drive to Queen Elizabeth Drive is included in this project. Footpath will be located on the north eastern side of Investigator Avenue to link up with Nautilus Drive, Canberra Avenue and the existing footpath across Mullins Creek.

Is Council going to build kerb and channel along Investigator Avenue?

The edge of both sides of Investigator Avenue from Nautilus Drive to Queen Elizabeth Drive will be supported by either kerb and channel or flush kerb. Flush kerb is not a raised kerb like kerb and channel, but a concrete kerb built at the same level as the bitumen (flush).

Why is there not going to be kerb and channel along the full length of road widening?

There are a number of factors that determine whether kerb and channel can be installed, including height of road above or below adjacent properties, verge slope and stormwater catchments. Every effort has been made to include as much kerb and channel as possible however not all locations are suited. Flush kerb serves the same function and achieves similar aesthetic.   

Where is this construction site located?

Please see attached plan. Nautilus Drive to Queen Elizabeth Drive, Cooloola Cove.

Is Council going to construct a new driveway at all properties?

Council will need to remove some driveways and culverts to facilitate road widening and changes to verge profile. These driveways will be reconstructed. All affected driveways will be reinstated to a like-for-like standard. Below is a list of properties and the works proposed for each.
