The centrepiece of the Great Yarmouth Third River Crossing project is a new 68-metre (trunnion to trunnion) twin bascule bridge that will provide a new link road across the River Yare.

A challenging movable bridge, marine and urban works project, with an ambitious 28-month programme
Roughan & O’Donovan (ROD) is leading the detailed design of the Great Yarmouth Third River Crossing project in Norfolk on behalf of BAM Farrans, a joint venture between BAM Nuttall and Farrans Construction.
In November 2020, the British Government approved funding of £98 million for this “nationally significant infrastructure project”. This followed the Planning Inspectorate’s decision in September 2020 to grant Norfolk County Council development consent for the construction, operation and maintenance of the new opening bridge across the River Yare in Great Yarmouth.
BAM Farrans JV started construction in January 2021 and, with progress continuing apace, the works are on track for completion by spring 2023.
ROD's partners are Hardesty & Hanover, who provide global expertise in moveable bridges, and Norfolk-based architecture firm, Pro:works.
Our team has extensive experience in:
The main feature of the scheme is a 50m clear span twin bascule bridge providing a new link across the River Yare in Norfolk to ease traffic congestion, reduce journey times and improve journey reliability.
Additional features include:
The scheme is centered in an operational marine port, with commercial and residential properties along the approaches to the river crossing. Poor soil conditions and low-lying ground add further complexity.
