Keynote 1
Keynote 2: Harmonising Bridge Design in a Climate Emergency
- The ideal bridge should be functional, sustainable, structurally coherent, aesthetic, and durable, as well as respectful of the history, culture and society of the site, appropriate to the environment and on the right scale with regard to the problem.
- In this presentation I will explain my view on how to achieve holistic bridge designs, in the context of the current climate emergency.
Concrete Repairs: A19 Tees Viaduct
- The A19 Tees Viaduct, or Tees Flyover is a high level 2.9km-long road bridge in the Northeast carrying the main A19 trunk road north–south across the river Tees. It has a total length of 2.9km.
- Since opening in November 1975, the structure has had problems with corrosion and repairs have been necessary at various times through its life to increase the longevity of the structure.
- CRL has been working on this structure since October 2020 and is currently working collaboratively with Sir Robert McAlpine on the 3rd phase of the project, which includes concrete repairs, surface preparation and cathodic protection to a further sixteen bents along the viaduct.
Session will be led by Concrete Repairs Limited
Minimising Embodied Carbon by Maximising Efficient Structural Design – Opportunities and Challenges
- Minimising the quantity of material specified is one significant way in which bridge engineers can reduce the embodied carbon in their designs and also reduce the cost.
- In reality, relatively few bridges are currently designed to the limits of the rules in the applicable design codes.
- This presentation will discuss some of the common reasons why designers are reticent to design for 100% utilisation and makes proposals for why and how they should re-consider their approach in many situations.
Inspection Manual for Highway Structures
- The Inspection Manual for Highway Structures (IMFHS) was first released in 2007; the document consisted of two complimentary volumes; Volume 1 was a reference document whilst Volume 2 acted as a quick reference for inspectors on site.
- National Highways decided in 2023 that a refresh of the document was required and employed WSP to undertake the work.
- The new manual is divided into 13 chapters; chapters 1 to 11 replace the original reference document; chapter 12 is the updated Inspector’s Handbook whilst chapter 13 provides informative references.
- The IMFHS is applicable to any individual or organisation in the UK who wish to use it.
- The presentation will describe the changes made with examples taken from the two volumes.
Speakers

Bridge Collapses and the Importance of Learning from History
- A reflection on collapses in the first quarter of this century.
- Details of collapse investigations.
- Some case studies.
- Are we sufficiently well resourced to prevent future collapses?
Rehabilitation of Cart Road Railway Underbridge, Cardiff
- Cart Road Bridge, Cardiff is a Grade II listed three span masonry railway underbridge which, before the works, was in very poor condition.
- This presentation will describer the project background and how it fits in within the wider Core Valley Lines works for Transport for Wales.
- Our paper will also examine mistakes that were made in the assessment and initial strengthening of this bridge which can apply to other masonry bridges and which dangerously overestimated the strength of the bridge.
- Lastly, we will present the latest advances used in the installation of the MARS System and discuss the problems associated with re-casing masonry bridges.
Caring For An Elderly Bridge Portfolio: How Network Rail is Examining its Aging Structures
- The long-term challenges that Network Rail faces with its aging bridges portfolio.
- How Network Rail’s examination regimes have been evolving and continue to evolve, to support engineers and asset managers make good decisions.
The AVA Footbridge
- An innovative footbridge for Network Rail.
- Designed for manufacture.
- Working with stainless steel thin sheets.
- The AVA footbridge was conceived as a disrupter to shake up the procurement, carbon cost and glacial speed of construction that still characterise the majority of conventional footbridge projects. It is also a beautiful, timeless piece of infrastructure, all made of stainless steel thin sheets.
Speakers
Building Bridges – a Pious Act?
- Strange as it may seem to us in the 21st Century, construction and repair of bridges was once considered an important act of charity. Benefactors were motivated by piety to give large sums of money towards their upkeep.
- This talk will give a fascinating insight into the religious motivation of our medieval ancestors and why they considered that making these donations for bridges might help to save their souls after death.
Bridges Awards Ceremony
- Introduced by Bridge design & engineering magazine and the organisers of the Bridges conference and exhibition in partnership with the Bridge Owners Forum, the biennial Bridges Awards aim to recognise and honour individual projects and/or organisations for outstanding achievement.

Bridgitise: An Industrial Doctoral Network for the Digitalisation of Bridge Integrity Management
- Bridgitise is a pioneering project that aims to advance bridge integrity management through the development and validation of digital technologies for bridge information management.
- The project will train 16 PhDs on themes related to innovative technologies to collect bridge data; AI and IoT technology to process and share data; and digital decision support tools to manage bridges' integrity across their life cycle.
- All the projects will go beyond the state of the art to move scientific developments closer to real applications.
Addressing the Infrastructure Condition Crisis Using Machine Learning and Digital Custodianship
- Our infrastructure is ageing, and at the same time, we're placing increasing demands and expectations upon it.
- This is becoming a critical national challenge.
