A8 Belfast to Larne

Case Study

The contract for the design and construct upgrade, of the A8 carriageway between Belfast and Larne was awarded to the consortium of Lagan Construction, Ferrovial Agroman and Costain. The scheme involves upgrading over 14km of the A8 between Ballyclare and the Port of Larne.

The A8 is a strategically important road linking the Port of Larne with Belfast and carrying in excess of 17,000 vehicles daily. Co-financed by the European Union Trans-European Transport Network, Northern Ireland Assembly and the Irish Government, the project will upgrade the final section of the A8 between Belfast and the Port of Larne and provide dual carriageway standard highways from Larne to the cross-Irish border at Newry and beyond into Ireland.

Banagher Precast Concrete manufactured and supplied eight bridges for the scheme, they consist of six over-bridges and two under-bridges. The over-bridges are made up of two spans in the region of 25m each and were constructed using Banagher W-beams. The under-bridges were built using TY beams for the shorter 15m span structure and Super-U beams for the larger 38m span structure.

Close collaboration between the Team in Banagher, the Contractor and their Designer played an important role in the overall optimisation of the structures on the scheme.

We would like to thank all those involved in the project from Lagan Construction, Ferrovial Agroman and Costain, and we look forward to working with them again in the near future.
