Preliminary design underway following community consultation in September and October 2019

About the project

Moggill Road and Coonan Street are two major arterial roads intersecting in a semi-controlled roundabout at Indooroopilly. The roads link Brisbane's outer west and south-western suburbs and the Brisbane Central Business District (CBD). 

The intersection caters for high traffic volumes and experiences significant congestion in peak hour periods, with:

  • 38,000 vehicles per day to the west of Moggill Road
  • 47,000 vehicles per day to the east of Moggill Road
  • 25,000 vehicles per day along Coonan Street.

Major queuing is experienced on approaches to the intersection, resulting in delays for all road users.

The intersection has a high crash history, with 32 recorded incidents between 2013-18, resulting in 10 hospitalisations and 17 requiring medical treatment.

The Moggill Road and Coonan Street corridors border commercial, retail and residential land area. The intersection also has limited pedestrian and active transport connectivity and accessibility.

The intersection will continue to provide a critical link to adjoining suburbs, the CBD and broader Brisbane for all transport modes, supporting commercial and residential development in the area.

Ensuring the intersection can cater for future traffic demands is critical, as well as providing safe and accessible transport options for all road users.

Community feedback

Council sought feedback on two concept design options to significantly improve safety at the intersection. Council met with the local community and key stakeholders and received overwhelming support to upgrade the intersection.

Approximately 82 per cent of feedback received during the project’s consultation phase, including at two public information sessions, supported the construction of an overpass (Option B). This option provides greater travel time savings to reduce congestion and can cater to existing and future traffic demand.

During the community consultation process Council listened to feedback from residents and stakeholders wanting to maintain the left turn access into Stamford Road. Council is pleased to announce that a revised overpass design to retain left turn access from Moggill Road into Stamford Road has been developed. This revised overpass option will now proceed to the preliminary and detailed design phases.

The feedback received as part of the consultation on the concept design will be included in the business case for the project.

Council appreciates all the feedback that has been provided by local residents and looks forward to continuing to work with the community in the development of this important project. Feedback is invited from the community throughout all stages of the project. Council will seek further community feedback once the detailed design is developed.

Video supporting information

The project  video shows drone footage with animations to highlight the two design options (Option A and B) for the Moggill Road and Coonan Street intersection upgrade at Indooroopilly.

The project video shows aerial footage of the Moggill Road and Coonan Street road corridors at Indooroopilly, highlighting the current intersection as a semi-controlled roundabout. The image shows connecting rounds, including Indooroopilly Shopping Centre to the south. The project video then shows the roundabout looking inbound towards the city, and labels Moggill Road and Coonan Street. 

The project video shows a birds-eye view of the roundabout facing south-east, and shows design option A – T-intersection. The current roundabout is overlayed with the design features, including installing new traffic lights to control all movements along Moggill Road and Coonan Street, new landscaping in front of Indooroopilly Central, and the dedicated turning and through traffic lanes on approaches to the intersection. The project video also shows that Moggill Service Road will be retained, and highlights dedicated bike lanes and additional footpaths around the intersection. 

The project video then shows an aerial image of the intersection facing north, with an overlay of option A design features and extent of the project works. Access changes at connecting streets are highlighted with call-out boxes, including removing the left turn movement from Moggill Road into Payne Street to improve safety and traffic flow, removing right turn movements from Stamford Road onto Moggill Road, removing left and right turn out movements from Nelson Parade onto Moggill Road, and making the Keating Street and Coonan Street intersection left in, left out only.

The project video then shows design option B – Overpass. Facing north, the current roundabout is overlayed with option B design features, including constructing an overpass for Coonan Street traffic that will allow Moggill Road through traffic to flow freely. The image shows new traffic lights at the Coonan Street road bridge and the entrance to Indooroopilly Central, dedicated turning lanes on Moggill Road and Coonan Street, new landscaping and traffic islands to separate vehicles, and providing dedicated bike lanes and additional footpaths around the intersection. The Moggill Service Road is removed, to accommodate the new road bridge.

The project video then shows an aerial image of the intersection facing north, with an overlay of option B design features and extent of the project works. Access changes at connecting streets are highlighted with call-out boxes. Option B includes changing the access to left in only at the Moggill Road and Nelson Parade intersection. This is required to accommodate the new road bridge, and remove potential conflicts for road users exiting Moggill Road to turn right onto the Coonan Street overpass. The left turn access from Moggill Road into Stamford Road will be removed to improve safety, as vehicles merging from the Coonan Street slip lane onto Moggill Road will be accelerating in close proximity to this intersection.

Option B also includes changing access at the Keating Street and Coonan Street intersection to left in, left out, and removing the left turn in movement at the Moggill Road intersection with Payne Street to improve traffic efficiency and safety for the free-flowing traffic on Moggill Road. Road users who previously used Payne Street to access local streets will need to use Nelson Parade, Waverley Road or Rokeby Terrace.

Project benefits

Once complete, community benefits include:

  • significantly improved safety for road users and pedestrians at the intersection and nearby streets
  • the overpass will improve traffic flow and reduce travel times. Commuters will save approximately 43 seconds along Moggill Road travelling inbound during the AM peak, and approximately 26 seconds outbound in the PM peak
  • better connected footpaths will improve pedestrian access for local residents and people travelling through the area
  • new on road bicycle lanes along Moggill Road will be installed and Council is investigating options for a cyclist connection between the intersection and the Walter Taylor bridge and the future Indooroopilly Riverwalk
  • Council is investigating additional upgrades to the local road networks, including at the Coonan Street and Allwood Street/Belgrave Street intersection and the Coonan Street and Westminster Road intersection.

Project features

The project will involve:

  • constructing an overpass that takes Coonan Street over Moggill Road, allowing through traffic on Moggill Road to flow freely
  • upgrading the existing Moggill Road service road, to connect the Coonan Street overpass with Moggill Road
  • changing access at Keating Street to remove the right turn in and out, to improve safety
  • changing access at Payne Street to remove the left turn in, to improve safety and traffic flow on Moggill Road
  • changing access at Nelson Parade to a no-through road, due to poor sight lines for merging vehicles and existing road constraints
  • providing additional sections of footpath through the project area
  • retain left turn access from Moggill Road into Stamford Road.

Investigation works 

Council is progressing the design and as part of this process will be undertaking additional survey works and geotechnical investigations in the area commencing mid July, for approximately six weeks. Depending on the location of the works, some activities may be undertaken at night between 7pm and 5am.

Road users and residents can expect the following over this period:

  • survey workers on the road
  • vacuum excavation and a geotechnical drilling rig
  • temporary lane closures in place on Moggill Road and Coonan Street, where required.

Due to the nature of the works, residents may notice an increase in noise and dust associated with the activities. The project team will provide additional notification prior to the start of the survey works.

The project team has created an SMS and email alert system to keep the community up to date with the latest project information.  If you would like to subscribe to receive further project updates and information, please call 1800 572 132 or email the project team.
