GRAHAM is pleased to share that we have successfully completed the A47 Breydon Bridge, in Great Yarmouth embarking on a journey of modernisation – revitalising critical infrastructure.

Commencing on the 4th of September 2022 and successfully concluding on the 31st of October 2023, the project has become a shining example of excellence in collaboration, innovation, and sustainability.

With an estimated value of £7.5 million, the scheme was led by GRAHAM working in collaboration with National Highways and contractors Safety Engineering Standards (SES) and Atkins.

Nestled between the Acle New Road roundabout and the Pasteur Road roundabout along the A47, Breydon Bridge, posed unique challenges. This project required a specialised supply chain to successfully execute the refurbishment and modernisation of mechanical and electrical operating equipment.

With the collaborative expertise of GRAHAM, SES and Atkins, the scheme aimed not only to address the complexities of the task at hand but also improve Breydon Bridge overall functionality and efficiency.

The Early Contractor Involvement (ECI) phase, conducted in advance of the site phase, saw a collaboration of minds to seek optimal solutions and requirements.

The engagement of key stakeholders, including Norfolk County Council, local marine-based businesses, and the wider community, was crucial. This ensured a harmonious coexistence with other concurrent projects such as the Third River Crossing and Harfreys Refurbishment.

Project Highlights:

Traffic Management: The project employed a mix of traffic management (TTM) signals, total closures, and the use of temporary vertical concrete barriers (TVCB) to ensure smooth operation.

Innovative Temporary Works: A suspended scaffolding system was crafted underneath the structure to facilitate the removal and reinstallation of hydraulic cylinders, alongside associated craneage for the removal of plant room equipment.

Mechanical and Electrical Refurbishment:

1.Mechanical Works: Replacement of hydraulic cylinders, connections to the deck structure, and reinstatement of existing personnel access platforms.

2.Hydraulic Works: Drainage, removal, and replacement of installation of manifolds, cylinders, oil, pipework, flushing, pressure testing, and commissioning of the hydraulic control system.

3.Electrical Works: Decommissioning, disconnection, and removal of redundant electrical control equipment, disposal of the existing bridge operating console, installation of new MCC Pump starters, PLC, HMI & SCADA console, new remote panels, and cabling.

Project Benefits:

The A47 Breydon Bridge project stands as testament to the synergy achieved through collaboration. With seamless integration with concurrent initiatives, including Third River, Harfreys Refurbishment, Vauxhall Junctions Surveys, OD Scheme works, demonstrating a cooperative ethos that goes beyond individual project realms. This collaborative approach not only streamlined project delivery but fostered a comprehensive approach to project management, ensuring that each process contributed to overall project success.

In addition to collaboration, the project demonstrated a commitment to sustainability. The incorporation of solar-powered compounds and lighting equipment highlights environmental stewardship. This forward-thinking approach not only resulted in substantial carbon savings but led to notable cost efficiencies and a reduction in fuel consumption. Demonstrating environmental consciousness, that sets a precedent for responsible infrastructure development.

The successful completion stands as validation of the capabilities of public and private collaboration, innovative problem-solving, and a commitment to sustainability. This project not only ensures the continued functionality of critical infrastructure but also sets a high standard for future projects, leaving a lasting legacy.

Andrew Harmon, GRAHAM Contracts Manager said:

“The upgrade presented a series of intricate technical challenges for the project team – making it a highly complex endeavor. The successful completion of this project serves as testament to the collaborative efforts of all involved parties. This approach not only streamlined project delivery but fostered a holistic approach to project management – ensuring that each process contributed to overall project success”.

Ajith Nair National Highways Project Manager added:

“This was a technically challenging scheme with various complexities, so the successful delivery exemplifies the collaborative working by all parties involved, keeping customer safety, minimal road disruptions and quality of work paramount”.
