Plans announced to tackle Severn Bridge corrosion

England's Highways Agency has announced a first phase of work to address corrosion in the main suspension cables of the M48 Severn Bridge. Work will begin in a few months to install a dry-air injection system on the middle section of both cables, where tests indicate that the worst corrosion has occured. An inspection programme began last year on the 40-year-old bridge as a precautionary measure after corrosion was found in the cables of bridges of a similar age and construction in the USA, Japan and elsewhere. "The dry-air injection system is designed to stabilise the condition of the M48 Severn Bridge cables while work continues to find a longer term solution," said the Highways Agency's network performance manager for the South West Patrick Carney.

Important Update: Bridge Design & Engineering Magazine


For more than 31 years, Bridge Design & Engineering has been a trusted source of new insights, knowledge, and connections for the global bridge community.  With the rapid shifts in the publishing landscape and increasing costs, sustaining the printed magazine at the high level of quality our readers expect has become increasingly challenging.  After careful consideration, Hemming Group Ltd has made the difficult decision to discontinue the print publication.


You will continue to have full access to the Bridge Design and Engineering website - including the complete archive. Although the site will no longer be updated, the archive remains a rich resource of engineering knowledge and project insight.  You can also continue to access the Bridge Directory, IBIG, through the website or directly at: https://www.bdeibig.com/


While this marks the end of an era, it also opens a new chapter, one focused on strengthening the connections, collaboration, and technical excellence that our community thrives on.  Our energy and investment will now be directed toward expanding and enhancing our industry leading events that bring the bridge community together.


Our flagship events Bridges and Bridges Scotland will continue to thrive as essential annual gatherings for bridge owners, managers, designers, engineers, and suppliers.  These events play a vital role in sharing innovation, showcasing best practice and emerging technologies, and fostering meaningful collaboration across the industry.  We are excited to build on their success and will further develop these events in the years ahead.
