The state government has announced the first stage of a plan to transform South Road into a continuous non-stop route from the Southern Expressway to the Port River Expressway - a distance of 22 kilometres.

The first stages include:

• construction of an underpass at the South Road and Anzac Highway intersection
• reconstruction of South Road with a series of underpasses taking the road under Grange and Port roads and the Outer Harbor rail line
• widening South Road between Port and Torrens roads.

The upgrade at these bottlenecks will reduce congestion and improve safety along South Road - Adelaide's busiest and most critical main arterial freight route.
