A notorious roundabout with a history of crashes in Brisbane's western suburbs will be replaced with an overpass and street lights.

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

A busy connection road between the western suburbs and the city, the stretch has 38,000 vehicles per day to the west, 47,000 to the east and 25,000 along Coonan Street.

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.
