DESCRIPTION:In May 2006\, the Glyn Bends section of the A5 trunk road in N
 orth Wales near Corwen was closed to traffic because there was concern reg
 arding the stability of a very steep rock cutting supported by anchorages.
    Many of the original anchorages installed only 6 years before were at r
 isk of failure due to corrosion because of as installed details.  Followin
 g road closure\, it was necessary to re-engineer the cutting by re-grading
  the north face to a safe angle that did not require anchorage support\, a
 nd re-anchoraging of the south face.  The road was reopened to traffic in 
 July 2007.\n\nThis presentation discusses the findings of the investigatio
 n of the failures of the original anchorages and the re-engineering of the
  cutting. The solution adopted was the one with the lowest level of risk\,
  in terms of cost\, programme and safety issues.
