Route
Where it terminates in Bedford Park, southwest of Adelaide's centre, Marion Road feeds into the Southern Expressway near the northern starting point of that road.
At its northern end, Marion Road terminates at Henley Beach Road. Route A14 continues west on Henley Beach Road for about 250 metres. It then travels north along the entire length of Holbrooks Road. At Grange Road it take a 50-metre dog leg to the east. It then continues north along the entire length of East Avenue until it ends at Port Road.
The Glenelg tram line has a level crossing in Plympton between Anzac Highway and Cross Road. The crossing in close proximity to two major intersections sometimes causes congestion during peak times, and has been the subject of political attention to convert the intersection with the tram line into an overpass. In April 2023, it was announced that the crossings would be grade separated in 2024.[3][4] Just south of the intersection of Oaklands and Daws Road, the Seaford railway line has an overpass over Marion Road.
