Comprised entirely of wrought iron, the superstructure is formed by four riveted double-lattice truss girders, supporting twin sets of cross girders and a steel trough deck bearing onto wrought iron lattice trestle piers. At an impressive 375m long, the bridge sits 40m above Melton Reservoir.

This demanding project involved Brunton Engineering & Construction staff working with rope access crews over a six-month period to perform periodic checks of the viaduct’s structural connections. The survey reported on the adequacy of thousands of structural fasteners as well as approximately 100 tie braces. This vital information was then forwarded to a leading engineering consultancy as part of the viaduct’s structural health monitoring regime.

Project highlights included:

  • Mobilisation of rope access technicians
  • Analysis and interpretation of existing structure to create custom checklists
  • Diligently checking and reporting on 3,000 structural connections
  • Effective performance of several multi-day inspections over a sixmonth period to assess structural integrity
  • Interpretation of checklists and provision of full structural health report to establish ongoing maintenance needs
  • Performance of required replacement works and on-the-job maintenance.
