  • Road over rail grade separation
  • Complex, inner city location
  • Intersection used by 21,300 vehicles per day
  • Five community consultation sessions held to decide final design

McConnell Dowell, in an alliance with the South Australian State Government, Mott MacDonald and Arup, are removing the level crossing at Torrens Road, Ovingham. The crossing is located near the fringe of the Adelaide CBD and an average of 21,300 vehicles pass through the crossing each day.

The junction of Torrens Road and Churchill Road is approximately 100 metres from the level crossing, and Torrens Road crosses both the interstate rail line and the Gawler passenger rail line. 

During the planning phase, the project team hosted five community information sessions (which were attended by over 150 people), and interviewed key businesses and residents within the project area. In addition, 366 survey responses were received during the planning phase, mostly from local residents and business owners. This feedback was used, along with technical advice, as part of an options assessment process to inform the selection of the preferred design solution, which is to raise the road over the railway line.

The new road bridge will have 89 piles in total, with 40 on the eastern side of the railway line and 49 on the western side of the railway line. The depth of piles will range from 15 to 24 metres into the ground.

Removal of the level crossing will lead to improved:

  • travel times for motorists
  • reliability for buses using Torrens Road
  • increased freight productivity
  • safety for all road users (motorists, cyclists and pedestrians) by removing a road-rail crossing point.
