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. There were 12 further incidents between 2018 and 2020 including 3 hospitalizations, 5 medical treatment and 4 minor injuries.

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

In late 2019, 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.

The majority of feedback received during the project’s consultation phase, including at two public information sessions, supported the construction of an overpass (Option B).

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.

Preferred design

Following the community consultation held in late 2019, Council’s project team has been working to refine the preferred design option and finalise the Business Case for the project.

The upgrade includes the construction of an overpass which will improve traffic flow, safety and active transport options as well as cater to existing and future traffic demands.

Feedback received by the community supported maintaining the existing left-turn movement from Moggill Road into Stamford Road.

Council amended the design to retain this left-turn access which provides an auxiliary lane for westbound traffic on Moggill Road, allowing a left-turn into Stamford Road. 

This preferred design option is progressing through the preliminary design phase.

The business case

The business case for the upgrade includes the options analysis process undertaken by Council, as well as feedback provided during community consultation that assisted Council in selecting the preferred design option.

Video supporting information

The fly-through video shows an aerial view with animations of Indooroopilly to highlight where Moggill Road and Coonan Street connect, labelling this as the location of the Indooroopilly roundabout upgrade. The video shows the Brisbane city centre in a north-eastern direction.

The fly-through then shows an animation of an arrow travelling north along Moggill Road under the underpass inbound to the Brisbane Central Business District (CBD). The video then shows an animation of an arrow travelling north along Moggill Road turning right onto the overpass and down onto Coonan Street. Next the video shows an animation of an arrow travelling north along Moggill Road turning right onto the overpass then turning left mid-way across the overpass into Indooroopilly Central.

The fly-through then shows an animation of pop-up labels to display that the existing crossing will be relocated to Moggill Road adjacent to Stamford Parade. Another label then shows that Stamford Parade will maintain left in and left out access.

The fly-through then shows an animation of an arrow travelling along Coonan Street turning left onto Moggill Road travelling outbound from the Brisbane city centre. The video then shows an animation of an arrow travelling from Coonan Street onto the overpass then turning right onto Moggill Road travelling inbound toward the CBD. Next the video shows an animation of an arrow travelling from Coonan Street onto the overpass and turning right mid-way across the overpass down to Indooroopilly Central.

The fly-through video changes its aerial view with animations of Indooroopilly to show the CBD in a south-west direction.

The fly-through video shows an animation of an arrow travelling outbound from the CBD along Moggill Road under the underpass and continuing along Moggill Road. The video then shows an animation of an arrow travelling outbound from the Brisbane city centre along Moggill Road then veering left to continue along Coonan Street. Next the video shows an animation of an arrow travelling outbound from the CBD along Moggill Road before veering left onto Coonan Street before making another left turn into Indooroopilly Central. The fly-through then shows an animation of an arrow travelling outbound from the Brisbane city centre along Moggill Road under the underpass then making a left turn onto Stamford Parade.

The fly-through video changes its aerial view with animations of Indooroopilly to show the CBD to the west.

Animations are used to show where traffic lights will be installed in three separate locations. These locations include on Coonan Street outside Indooroopilly Central before the onramp to the overpass; at the top of the overpass at the intersection of the Moggill Road Service Road and Coonan Street; and when turning left outbound from Stamford Parade.

The fly-through video then shows animated pop-up labels to display the first two entrances into Indooroopilly Central on Coonan Road travelling outbound from the CBD are entrance only and the third is exit only. The video then shows animated dotted lines and a pop-up label to display a left in and left out access from Keating Street onto Coonan Street.

The fly-through video shows an animated pop-up label to display that the bus stop has been relocated to Moggill Road before the overpass when travelling inbound to the CBD. Another label and dotted lines then display that Stamford Parade will maintain a left in and left out access. Another label then shows that the existing crossing will be relocated to be situated on Moggill Road adjacent to Stamford Parade. Next the fly-through video shows an animation of dotted lines along the outside lane of Moggill Road to indicate a dedicated bike lane.

Project benefits

Once complete, the Indooroopilly roundabout upgrade will:

  • improve safety for road users and pedestrians at the intersection and nearby streets
  • improve traffic flow and reduce travel times with the construction of an overpass
  • upgrade shared pedestrian and cycle paths, improving active travel opportunities and connectivity
  • improve the overall visual appeal of the intersection through new landscaping spaces.

Project features

Features of the preferred design include:

  • 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
  • closing Nelson Parade at Moggill Road due to poor sight lines
  • providing shared pedestrian and cycle paths through the project area
  • retain left turn access from Moggill Road into Stamford Road.

Council is also investigating options for a cycling connection between the intersection, the Walter Taylor Bridge and future Indooroopilly Riverwalk.

Investigation works 

While Council is progressing the design for the upgrade, additional investigation works will be carried out at various times. Depending on the location of the works, some activities may be undertaken at night between 7pm and 5am. 

Road users and residents can expect:

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

Notification will be provided to local residents and businesses when timing for these works is confirmed.

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, phone 1800 572 132 or email the project team.
