A notorious roundabout with a history of crashes in Brisbane's western suburbs is set to be replaced with an overpass and street lights in mid 2020. 

The Moggill Road-Coonan Street roundabout at Indooroopilly has had 32 crashes in the past five years, 10 of which required hospitalisation.

The intersection at Coonan Street will now be modified to create an overpass allowing inbound traffic leaving the street to clear Moggill Road and merge safely, and will be funded through the joint council and federal $500 million suburban roads fund.
