Removal and replacement
In some cases, the works included:
- removing the existing bridge structure and replacing it with a new one
- installing new safety barriers
- laying a new road surface.
Rehabilitation
At other locations, the bridge structures were rehabilitated to improve the lifespan of the structure by:
- removing the existing surface
- making the structure stronger with additional steel or concrete
- laying a new road surface.
Cathodic protection
We also undertook cathodic protection works at 2 locations, which helped to protect against corrosion. Watch our video for more information on this process.
