From the city centre (e.g. train station) take bus 3 to the south of town until the stop Mariazeller Straße/Info Point. You will see the ramps of the highway A1 (another name of this highway is Westautobahn). Follow the ramp a few meters up, then there's a little place to your right hand where cars can stop.
