Works were completed in 2016 to upgrade the Mitchell Freeway diamond interchange to dual carriageway with a second overpass bridge, extra turning lanes, and a new looped freeway ramp. The project aims to lower congestion, and reduce the volume of traffic using local roads to avoid the interchange. The works also included upgrading the Duffy Road South intersection to traffic light control, and widening highway to the west of Duffy Road, as well as duplicating it from Duffy Road to Erindale Road.
