Fiddlers Elbow Bridge

The Fiddlers Elbow Bridge consists of two separate bridge decks, each deck includes three supported spans which carries the A472 across the River Taff at the busy A470 Abercynon roundabout interchange. When the bridge was constructed in the early 1980’s mining subsidence was anticipated and design provision made.

Griffiths were appointed to replace eight of the existing modular bridge deck expansion joints at the East and West abutments as well as the East and West Piers.

Works for this project involved:

  • Installation of temporary access scaffold beneath the bridge deck at joint positions
  • Removal of existing deck joints (hydro-demolition) and replacement with new

Works were completed to meet the set deadline whilst incorporating all the additional works instructed.
