Bridges and Viaducts

Bridges are an integral part of a transportation network. While bridges play a strategic role in providing access to transport, we also recognise the fact that they serve as an important tool in connecting and bringing communities together.

At HHO, we have won many prestigious awards over the years, and we have experience in the planning, design, structural analysis, project management construction, inspection, maintenance and rehabilitation of a wide variety of new and existing bridge structures. The scale of projects ranges from the provision of simple culverts to major viaducts.

Our impressive portfolio includes many new bridges and we have extensive experience in the modification, strengthening and rehabilitation of existing bridges. We can provide a comprehensive service for our clients in the multi-faceted world of bridge engineering, and can assist with the design of:

  • New road and rail bridges
  • River crossings
  • Flyovers, directional ramps and viaducts
  • Widened and strengthened existing bridges
  • Rehabilitation of existing bridges
  • Routine and special bridge inspections

Notable projects include the multi-award- winning Koeberg Interchange, as well as the Gautrain Viaducts in Pretoria. The Ugie Langeni viaduct in the Eastern Cape is also a landmark structure that has earned us much praise.
