Upon the highway's commencement it is carrying both State Route 3 (continuing from Reid Highway) and National Highway 95 (continuing from Great Northern Highway to the north). The highway then curves to the south, reaching Toodyay Road later. From there the highway briefly borders the suburb of Stratton before entering Midvale, reaching another traffic light controlled intersection with Morrison Road later. Only another takes the highway to Great Eastern Highway at a modified diamond interchange with a northbound to eastbound loop ramp to cater for heavy vehicles. At this interchange, National Highway 95 terminates here, and simultaneously gains the National Highway 94 allocation, continuing from Great Eastern Highway to the east.

When the , $75 million extension from South Street to Kwinana Freeway was completed in March 2006 (Roe Highway stage 7), this meant that Hope Road was severed to the connection of the freeway with the road east of Berrigan Drive being renamed to Karel Avenue.
