Robertson Drive


Robertson Drive, also known as the Bunbury Bypass, Bunbury Ring Road, or Bunbury Inner Ring Road, is a road in Bunbury, Western Australia. It forms a partial ring road around Bunbury, allowing highway traffic to bypass the city centre. The road connects four highway routes that radiate out Bunbury: Forrest Highway to the north, South Western Highway north-eastbound and south-east bound, and Bussell Highway to the south. A dual carriageway along the route was completed in 1992.

Route Description

The northern terminus of the highway is at the Eelup Roundabout, a large, traffic light controlled roundabout that distributes traffic to Koombana Drive, Sandridge Road, Robertson Drive and Forrest Highway. Traffic coming from Forrest Highway has a slip lane that allows free flowing of traffic onto Robertson Drive, whereas the southbound Forrest Highway traffic must proceed through 2 sets of traffic lights. After the roundabout, the road continues South as an 80 km/hr zone. There is a traffic light controlled intersection with Picton Road and South Western Highway, from which the road becomes a 70 km/hr zone. The road crosses over the Australind railway line and then descends into the Bunbury Industrial Area, with a major traffic light controlled intersection with South Western Highway and Brittain Road. The road continues south, now an 80 km/hr zone, followed by a sharp turn towards the west, meeting an intersection with Sommerville Drive. Following the Sommerville Intersection, there is access provided to TAFE, the ECU Campus and the Hospitals. The roads southern terminus is with Bussell Highway at a roundabout with Bussell Highway gaining the State Route 10 marker in the southerly direction.
