Darlington bridge upgrade

Work to install a 3,000 tonne, 180 metre bridge as part of the Darlington Upgrade Project has been completed well ahead of schedule.

After months of planning, the Darlington Upgrade Project delivery team successfully manoeuvred the first bridge into place without a hitch over the weekend – with the roads reopening almost 24 hours ahead of schedule.

The 3,000 tonne, 180 metre bridge was constructed ‘off-site’ on land adjacent to the existing highway and then moved into place using self-propelled modular transporters - or SPMTs.

Laing O’Rourke is delivering the $620 million Upgrade Project in joint venture with Fulton Hogan as part of the Gateway South consortium. The project will deliver the 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
