HOCHTIEF demolished and replaced four road-over-rail bridges in central London as part of TfL’s Structures and Tunnels Investment Portfolio (STIP). Highbury Corner Bridge carries the busy A1 over two rail lines and Highbury & Islington Overground Station and sits under the Highbury & Islington Station forecourt.

Key features:

  • Road-over-rail bridge deck demolition and reconstruction
  • Abutment refurbishment
  • Complex utilities diversions
  • Traffic Management
  • Phased reconstruction

With the bridge carrying over 25k vehicles a day in a very busy urban area, we completed the works in phases to limit disruption to the travelling public. We successfully demolished and replaced the first section of bridge over the London Overground line and beneath Highbury & Islington Station during two rail possessions in July 2016 and Easter 2017, maintaining road access and completing the works right first time. We then completed the main demolition and replacement works over Christmas and New Year 2017/18 during an eight-day rail possession and three-week closure of the A1.

During the A1 road closure, our detailed phasing and logistics plans kept the public safe and clear of demolition works. We worked closely with TfL to plan efficient Traffic Management (TM) and we gave the public advanced warning of the closure, bus route changes and diversions. As pedestrian traffic increased dramatically around match days at the Emirates Stadium, we made major changes to hoardings and barriers to accommodate people flow, carefully managing vehicle movements and implementing specific crowd control to ensure the safety of the public.

We achieved a Considerate Constructors Performance Beyond Compliance award and successfully completed Highbury Corner bridge on time. The bridge was also selected as a finalist for Infrastructure Maintenance Project of the Year at the BCIA Awards 2018.
