Cass Hayward LLP
BWB Consulting provided engineering design services for series of road bridge replacement schemes in Monmouthshire.
The LLandevenny Bridge required full reconstruction as part of Network Rail's plan to electrify the South Wales Mainline. The existing bridge had reached the end of its serviceable life and was too low to accommodate overhead line equipment needed to power the electric trains.
BWB's Transport and Infrastructure team delivered the detailed highway and drainage designs that would allow for the raising the bridge. Our designers produced alignments that worked within the available highway land while minimising the impact on visibility and road safety. Our Transport Planning Team also played a key role, carrying out Road Safety Audits.
The existing structure was demolished during Christmas 2016 and the replacement bridge opened to the public the following year.
