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.
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.
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.

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.
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.
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.
