The Patrick Jonker Veloway (formerly known as the Adelaide Southern Veloway) is a sealed bikeway in metropolitan Adelaide, South Australia, designed for the exclusive use of cyclists. It runs continuously alongside the Southern Expressway for a distance of 7 km — from Marion/Main South Road to the Panalatinga Tunnel. South of the Panalatinga Tunnel, the bikeway becomes a shared track for the remaining 12 km of the Southern Expressway.
The Veloway provides important links to other cycling facilities in the area, notably the Sturt River recreational trail at its northern end, and the Coast to Vines rail trail at both Panalatinga Road and the southern end of the shared track. The northern end links to the Sturt River shared path, providing an almost non-stop bicycle route between Glenelg and Willunga.
The Veloway was officially opened on Sunday 22 February 1998 by South Australian Transport Minister Diana Laidlaw MLC. It is a legal entity that accords with the South Australian Road Traffic Act, and only people on bicycles are permitted to use the facility. The Veloway has challenging inclines in both directions of travel and a well-maintained coarse asphalt surface. The southern end is at a higher elevation than the northern end, making transit in the northerly direction the easiest. The Veloway offers views of the Adelaide metropolitan coastline, Adelaide plains, and Glenthorne Farm. Cyclists normally do not encounter pedestrians or vehicles on the Veloway, making it one of the safest transit corridors to ride in Adelaide.
The shared track section, identical in construction and markings to the Veloway, passes atop rolling hills through the suburbs of Reynella, Morphett Vale, and Hackham. It does not utilise the Southern Expressway's Sherriffs Road overpass; instead, there is a traffic light crossing at Sherriffs Road, with a narrower bitumen path leading to a crossing at Brodie Road, which it runs adjacent to before rejoining the expressway.
The Veloway was originally named the Adelaide Southern Veloway and was later renamed in honour of Patrick Jonker (born 25 May 1969), an Australian professional road cyclist of Dutch ancestry. Jonker raced from 1993 to 2004, competing in five Tours de France and achieving notable victories including the 2004 Tour Down Under, the 1997 Route du Sud, and the 1999 Grand Prix de Wallonie. He represented Australia at the 1992 and 1996 Summer Olympics.
