Summary

Roughan & O’Donovan 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. 

Our partners are Hardesty & Hanover, who provide global expertise in moveable bridges, and Norfolk-based architecture firm, Pro:works. 

Our team has extensive experience in: 

  • Design of moveable structures 
  • Design of bridges in tidal rivers 
  • Deep foundation design 
  • Integration of permanent and temporary works 
  • Design of urban highway schemes

Solution

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: 

  • Junctions with the A47 to the west and South Denes Road to the east 
  • Dual carriageway approach roads 
  • Two single span bridges 
  • Reinforced earth pile-supported approach embankments 
  • Feature landscaping on the quayside to create a new public realm 
  • Flood protection works

Development consent order

Norfolk County Council applied to the Planning Inspectorate for a development consent order to construct, operate and maintain the bridge and approaches. 

The application integrates ROD’s and H&H’s successful tender design for the structures with the council’s specimen design for the highway works. 

A detailed examination of the scheme commenced in September 2019. 

Construction is expected to commence in late 2020, subject to development consent.

Challenge

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.
