In the search for more validated circular viaducts, Rijkswaterstaat launched the Circular Viaducts SBIR ('Small Business Innovation Research') call at the beginning of 2020. From all proposals submitted, the BESIX - NEY & Partners consortium was one of the ten parties selected to further develop their circular concept. In recent months, the team has worked hard to elaborate a feasibility study on technical feasibility, environmental impact and economic perspective.
