Construction of a new Outer Harbor rail overpass as part of the Torrens Road to River Torrens North-South Corridor Project has begun with piling and retaining wall works.
The overpass will separate Outer Harbor and Grange trains from vehicle traffic on South Road, improving safety and travel times for motorists.
A pre-cast concrete retaining wall on the eastern and western sides of South Road is being constructed in preparation for the bridge installation in January 2017.
Approximately 270 tonnes of Arrium steel is being used in the pile reinforcement, rail tracks and concrete deck reinforcement.
South Australian contractor Samaras Group is fabricating the 720-tonne bridge structure.
The rail overpass will also feature a shared cycling and pedestrian path, completing a key link in the Outer Harbor Greenway.

The Darlington Upgrade Project is another important stage in the delivery of Adelaide’s North-South Corridor and will deliver an upgrade of approximately 3.3 kilometres of the existing Main South Road, including:
A non-stop motorway between the Southern Expressway and Tonsley Boulevard
A lowered, non-stop motorway passing underneath Flinders Drive, Sturt Road, Sutton Road/Mimosa Terrace and Tonsley Boulevard
Grade separation of the Main South Road/Ayliffes Road/Shepherds Hill Road intersection
Main South Road (at grade) surface roads along both sides of the lowered motorway to provide connections to Flinders Drive, Sturt Road and most local roads
Full free flow interchange at the Southern Expressway/Main South Road with dedicated ramps providing direct access to the new motorway and Main South Road.
The Marion Road/Sturt Road intersection has also been upgraded to cater for the redistribution of traffic during the construction period.
The $620 million Darlington Upgrade project is jointly funded by Australian and State governments ($496 million federally funded and $124 million state funded).
