Design and construction of the A4232 Eastern Bay link phase 1, Cardiff, UK

Completed in 2017, the first £57 million phase of Cardiff’s Eastern Bay Link provides a much-needed extension to the Welsh capital’s A4232 Peripheral Distributor Road through its busy docks area. Providing significant community and environmental benefits, the 1·2 km scheme includes a 21-span viaduct and transition structure spanning access roads, a railway line and numerous buried services on a highly congested site. Early contractor involvement and a collaborative contractual approach enabled the project team and stakeholders to accommodate significant design changes to ensure successful delivery of the project safely, on time and within budget.
