Bridge Street Newport
Network Rail is undertaking the Great Western Route Modernisation (GWRM) electrification project. The Great Western Main Line is one of the country’s most important arterial routes, linking London and the south-east to Bristol, Wales and the west.
- Year: 2016
- Location: Newport, Wales
- Client: ABC Electrification
Network Rail intends to electrify the line by installing 25kV AC Electrified Overhead Line Equipment (OLE). As part of the scheme, Bridge Street has been designated as a bridge reconstruction to accommodate the increased height of the OLE.

CBUK scope of work was to plan and supervise the removal of the existing structure, which involved the fitting of steelwork to strengthen it so that it could be lifted out. Our scope also included the planning, detailing, supply, fabrication, site assembly and heavy lift installation of the replacement structure, and installation of the precast concrete deck units.
To meet a short, six-hour deadline for the removal, CBUK fitted additional steelwork to the old bridge to strengthen the structure before it was lifted by a 600 tonne-capacity crawler crane, which enabled it to be removed in a single piece. Installation of the new bridge, which took place during a weekend closure of the railway line, also utilised the crawler crane and was successfully completed within three hours of receiving confirmation of the line closure.
As well as the successful removal and disposal of the old bridge for recycling, and the installation of its replacement within an extremely tight timeframe, the new bridge has been designed as an improvement on its predecessor. The project won “Project of the Year” from Construction News.
Congratulations to the team for an excellent performance and lots of very hard work over the past few months, ensuring a very challenging structure was ready for the lift.Rob Fancourt Head of Civils ABC
