Roe Highway is a 35 km (22 mi) limited access highway and partial freeway in the south-eastern suburbs of Perth, Western Australia, linking Middle Swan in the north-east with Bibra Lake in the south-west. It is primarily allocated State Route 3 and forms half of Perth's outer ring road along with Reid Highway, which it joins onto at its northern terminus.
The highway is one of the key heavy vehicle routes in the Perth metropolitan area. Aside from intersections, the speed limit is 100 km/h (62 mph) for most of its length. Twenty kilometres (12 mi) of the highway, between Kwinana Freeway and Tonkin Highway, is a continuous freeway, with grade-separated interchanges and free traffic flow. The rest of the highway is the standard of Perth's major highways; limited access, with few grade separations and traffic lights.
Roe Highway is multiplexed with National Highway 94 from Great Eastern Highway Bypass to Great Eastern Highway, and also National Highway 95 from Great Eastern Highway to Great Northern Highway.
Most junctions on the highway are grade separated diamond interchanges south-west of Tonkin Highway, and at-grade traffic light controlled intersections to the north-east of Tonkin Highway. The exceptions are at: Great Eastern Highway, a modified diamond interchange with a northbound to eastbound loop ramp; Clayton Street and Maida Vale Road, which are grade separated, but with only northbound exit and southbound entry ramps; and the terminus at Kwinana Freeway, a trumpet interchange. There is a diamond interchange at Tonkin Highway, with the free flowing traffic on Tonkin Highway, and traffic light controlled intersections on Roe Highway at the entry and exit ramps.
