Expressways
In South Australia, expressway may refer to a controlled access highway with no at-grade intersections or a limited access road of slightly lower standard with at-grade intersections at some locations. Currently there are three constructed expressways in Adelaide:
- Southern Expressway 21 km (13 mi) (the world's longest reversible one way freeway), completed in 1997
- Port River Expressway 5.5 km (3.4 mi), completed in 2008
- Northern Expressway 23 km (14 mi), completed in 2010
A fourth, the Northern Connector is planned, however this will simply be an extension of the Northern Expressway.
