Traffic regularly comes to a standstill between Purmerend and the Coenplein interchange. Rush-hour lanes are the chosen solution. The West-Nederland Noord division of the Directorate-General of Public Works and Water Management asked Movares to identify all the effects this would have in terms of ecology, air, noise, water, soil, safety, traffic, landscape, archeology and cultural history. This information will then be used in the environmental impact assessment and the provisional and final route decisions.
