SALAMINA - PERAMA UNDERWATER
TUNNEL AND APPROACH ROAD NETWORK
DESIGN BUDGET : US$ 40 Million
CLIENT : MINISTRY OF ENVIRONMENT PLANNING AND PUBLIC WORKS

The design was carried out in collaboration with HELLENCONSULT. TRITON was heavily involved in carrying out the geotechnical investigations both onshore in the Perama and Salamina coastal areas and offshore along the axis of the underwater road tunnel. Stability analysis and alternative methods of improvement of the soft alluvial seabed deposits were studied. Geological investigations, rock slope analysis and detailed cross section design of all coastal approaches to the tunnel including the motor way were carried out for both Perama and Salamina coastal areas.

Finally foundation parameters were established both for the underwater tunnel and all the bridges, retaining walls and related works all along the road approach network.
