Modern Methods of Construction - The Colne Valley Viaduct being delivered by the Align JV as part of HS2 Phase One in the UK

14:20 - 14:40
  • When completed, the 3.4km-long Colne Valley Viaduct (CVV) constructed as part of Phase 1 of High Speed 2 (HS2) will be the longest railway viaduct in the UK.
  • This precast, segmental, post-tensioned concrete box girder viaduct has been erected by an overhead gantry – the only one of its kind currently being employed in the UK.
  • This 650t gantry has been used to erect the segments of the viaduct through both balanced cantilever and span-by-span methods.
  • This method of erection and choice of erection equipment has enabled the viaduct to be constructed entirely above pier head level, with segments rear fed to the gantry at deck level, delivered by trailer on the previously erected spans.
  • This has minimised disruption both on the surrounding roads and the highly environmentally sensitive bodies of water and woodland areas, northwest of London, which the viaduct spans.
