Bridge screen policy

Roads ACT is committed to the improvement of safety levels on bridges through a bridge strengthening (and replacement) program aimed at increasing load limits on bridges and the bridge safety screen program aimed at ensuring that the likelihood of accidents caused from an object thrown off a bridge at a vehicle passing below is minimised.

Bridge inspections

Bridge inspections ensure that bridges continue to function under acceptable conditions of safety and that they are maintained with an acceptable level of expenditure. Bridge inspections achieve these aims by monitoring the following:

  • continually assessing the state of bridges to safeguard users;
  • recording current bridge conditions;
  • providing feedback on design, construction and maintenance;
  • checking the effects of changes in vehicle loading and traffic volume;
  • monitoring long term performance of structural elements and materials;
  • providing information for the management system;
  • providing information for load capacity ratings; and
  • establishing a history of performance.

The frequency of bridge inspection is dependent on the condition and use of the bridge, by regular and heavy vehicle traffic. In usual circumstances a heavily used bridge will be inspected every six months, a less frequented pedestrian bridge for instance may be inspected once every four years. After an exceptional event, for instance if a vehicle hits a pylon, or after a flooding a bridge will be given a safety inspection. New bridges and bridges that have been upgraded are also subjected to a hand-over inspection.

If you discover any problems with the condition of any of our infrastructure please contact visit the Access Canberra website or call 13 22 81.
