Abstract

The South African National Roads SOC Agency (SANRAL) identified two bridges on the N12, section 9 to be widened and improved. The bridges were to be repaired of their existing structural defects and widened to allow safer passage of traffic and pedestrians along the route. Repairs to concrete, replacement of existing structural elements and retrofitting of improved elements were undertaken simultaneously to bring the bridges up to specification and safety standards. Through this effort, the bridges durability and lifespans were greatly improved and prolonged. Further substantial benefits were injected into the local environment and community through job creation and education with the local population of the area.
