In order to alleviate worsening traffic load issues in the city of Karlovac, the Rijeka-Zagreb Motorway authority designed this project to create a feasibility study on relocating a part of state road D6 to improve traffic flow. Consortium has developed three conceptual solutions for the proposed road connection, including impact research on the local community and the environment, financial analysis, cost-benefit analysis, and risk assessment. The analysis identified the optimal course for a 4.5km segment of road and proved the project’s feasibility, and social benefit.
