ABSTRACT

The Naples Line 6 underground Metro is part of an integrated network of railway transport with several interconnection nodes with other railway lines (metropolitan and regional railway systems).

The line is currently operating in the Mostra-Mergellina section with 4 stations. The section currently in construction, Mergellina-Municipio, crosses the central and most attractive areas of the city, behind the coastal strip. The line lies under the groundwater level along the whole length; the free water level for the most part is just a few meters below ground level.

The next step is the construction of the following: a. the tunnel from the Mostra station to the Campegna station, in the Bagnoli area; the final depot in the ex military arsenal area (below the Posillipo hill).

The design and construction of a metropolitan transportation system in a big city like Naples requires complex and in-depth analysis that was developed since the feasibility studies and in the end were considered in the municipal transport plan of the city of Naples.

This paper describes the transport analysis at the base of the conceptual design of the line, the environmental compatibility studies, the process for the stackholders involvement and communication, the urban integration of the system, the costs/benefits balance and the financial analysis issued for Naples Line 6 underground metro project.
