Sizewell C has awarded key new UK contracts for road and infrastructure work as it prepares to take significant steps forward in building the off-site infrastructure needed to help construct the nuclear power station on the Suffolk coast.   

The Sizewell C project – which will deliver 70% of its construction value to British suppliers and recently announced it had signed nearly 300 UK contracts worth £2.5bn – has awarded high value contracts to UK company Galliford Try to construct a new 6.5km Sizewell Link Road and a new 1.8km Two Village Bypass, and to Suffolk-based, family-owned civil engineering contractor, Breheny Civil Engineering, to build two new connecting roundabouts on the A12.  

The contracts follow the earlier multi-million award to Ipswich-based Jackson Civil Engineering to deliver key road schemes for the project.
