Replacement of two track single span bridge

Elland Road, Leeds

New bridge construction

Highfield Lane, Sheffield

  • Off site pre-casting of all concrete bridge components including approach retaining walls
  • Pouring of deck compound once the bridge was assembled
  • Excavation of abutments, landing jack, placing of retaining walls in weekend possession

 

Innovation: Use of couplers to ease congestion in a heavily reinforced area.

Abutment and central pier pile cap foundations constructed in situ; circular columns and top cross-head beams, permanent form-work and parapet temporary works erected during possession; construction of concrete deck, parapets and approach slabs

 

Innovation: As much temporary works and permanent form-work installed prior to bridge placement to minimise critical possession durations. Used joint-less circular form-work system to produce very high quality surface finish.
