The project map
Vesima East viaduct widening
Asset dating back to the first construction phase of the A10 (1930s). The asymmetrical widening is necessary to allow for the creation of the new eastbound carriageway of the Gronda from the existing A10 which continues towards Voltri.
Vesima West viaduct widening
Asset dating back to the second construction phase of the A10 (1970s). The asymmetrical widening is necessary to allow for the connection of the new westbound carriageway of the Gronda with the existing A10, which continues towards Ventimiglia.
Borgonuovo East and West tunnels
They will be excavated mechanically using a TBM. Length of each tunnel: approx. 2.2 km
New Cerusa East and West viaducts
The two new viaducts solve the crossing of the valley of the Cerusa stream in Voltri on the east and west carriageways of the Gronda.
Ciocia Tunnel
It will be excavated traditionally. Length: approx. 460 m
New Leiro East and West Viaducts
The two new viaducts solve the crossing of the valley of the Leiro stream in Voltri on the east and west sides of the Gronda.
Amandola East and West Tunnels
They will be excavated mechanically using a TBM. Length of each tunnel: approx. 6 km
New Varenna East and West viaducts
The two new viaducts solve the crossing of the Varenna stream valley by the east and west carriageways of the Gronda.
Maritime work
Part of the excavated material from the construction of the tunnels will be relocated in the vicinity of Genoa Airport, in the ‘Maritime Work’. The area in which it will be constructed is the existing Calma Canal of the Port of Genoa, the harbour basin between the Genoa Airport platform and the Breakwater.
Monterosso East and West Tunnels
They will be excavated mechanically using a TBM. Length of each tunnel: approx. 6.2 km
New viaduct Genoa
The new viaduct crosses the Polcevera valley at the height of the municipality of Bolzaneto
