| Abstrait: | Since the 60’s, the structures of Herstal Viaducts have suffered from a dysfunction of expansion joints, drainage system and been exposed to a high level of corrosion. On top, existing road layout, without shoulders and insertion/deceleration lanes at connection to existing junctions, lead to an unsatisfactory level of safety. During 2012, Belgian road directorate (S.P.W.) has developed and implemented an extensive inspection plan and design program to assess the existing structures. An important public works contract has been awarded early 2014 to refurbish, strengthen and upgrade the existing viaducts. | ||||
