The project map

The motorways in Genoa now also serve as a bypass for urban traffic with very high volumes. Many points on the network experience over 60,000 transits per day, with a significant number being commercial vehicles. It is essential to separate city traffic from through-traffic and port-related flows. The Gronda di Genova Project aims to ease the congestion on the A10 section most connected to the city of Genoa, from the Genoa West exit (Port of Genoa) to the Voltri built-up area. This will be achieved by diverting traffic to a new infrastructure alongside the existing one, effectively creating an 'off-site' expansion.
 

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

Polcevera Tunnel, San Rocco, Forte Diamante

They will be excavated traditionally. Polcevera: approx. 530; San Rocco: approx. 1 km; Forte Diamante: approx. 2.8 km

Morego Tunnel

Torbella West, Forte Diamante, Bric du Vento, Torbella East Tunnel

They will be excavated traditionally. Torbella West: approx. 100 m; Forte Diamante: approx. 2.8 km; Bric du Vento: approx. 2.4 km; Torbella east: approx. 1.4 km

Montesperone Tunnel

It will be excavated traditionally. Length: approx. 2.4 km

Campursone Tunnel
