ACS - Actividades de Construcción y Servicios SA is set to participate in one of the largest highway projects in the Netherlands through its involvement in the GelreGroen joint venture. The project, located in the Arnhem area, involves extending the A15 highway by twelve kilometers and widening the A12 and A15 with new lanes over a 23-kilometer stretch. The project, scheduled to begin in January 2026, will also include the construction of 45 bridge structures, ten traffic junctions, and additional noise barriers, with a significant feature being a new 2.5-kilometer bridge over the Pannerdensch Canal. The joint venture, comprised of HOCHTIEF, John Laing, Dura Vermeer, and BESIX, emphasizes sustainability with a "nature inclusive design" approach. The highway is expected to be opened by the end of 2031, and the contract includes provisions for financing, operation, and maintenance until 2051.
