Costain and joint ventures of which it is part were paid around £900m in the period. This included £366m for the Costain/Skanska joint venture on the A14, a job on which Balfour also worked. Work on the road to Cambridge was completed ahead of schedule last year. Its A-One Integrated Highway Services collaboration with Jacobs and Colas made another £358m through work on schemes such as the A64 carriageway renewal.
