Featured image: steel plates for M4 bridge repair

steel plates manufactured and installed by BS Steels for M4 motorway viaduct repairM4 Boston Manor Viaduct repairs, 2012. Special steel plates bolted above and below cracks to the web. In addition to the bolt plates, filler plates were required on both sides, between the structure and the new bolt plates; these were milled to match as exactly as possible the unique profile and undulations of the existing structure. This had to be done for around 30 separate locations. Multiple tension control bolts needed systematic tightening during overnight closures, to eliminate traffic loads. Visit project page
