OBahn City Access Project

The O-Bahn City Access Project was part of the South Australian Government’s investment in building a stronger public transport network. The Project included the creation of centrally aligned priority bus lanes along Hackney Road, and a dedicated 650m bus tunnel from adjacent the National Wine Centre to near Grenfell Street, providing quicker, more reliable access for O-Bahn buses into the city. WGA led the structural design as well as undertaking the following:

  • Traffic modelling verification and design of intersection signalling 
  • Lighting design for road, handrail, car parks and shared paths
  • Temporary works design for the installation of the shared-used path over the River Torrens
  • Proof engineering and independent verification services for the civil components of the project.
