A7 A10- A12 - A26 Genoa BYPASS
The new infrastructure includes 72 km of new motorway routes and is connected to the junctions bordering the city area (Genoa East, Genoa West, Bolzaneto), is connected to the A26 to Voltri and re-joins the A10 at Vesima. Given the orthographic complexity of the territory crossed, the new road system is constructed almost entirely underground and includes 23 tunnels, for a total of approximately 54 kilometres, approximately 90% of the entire route, with variable sections of up to 500 square metres of the interconnecting areas between the motorway routes.
The outdoor works include the construction of 13 new viaducts and the expansion of 11 existing viaducts.
The motorways of the Genoa area are currently also used as ring roads for urban traffic and crossovers with very high volumes of traffic; at many points of the network, flows exceeding 60,000 daily transits are recorded, with a high percentage of commercial vehicles. It is therefore essential to separate the city traffic from the crossings and flows associated with the port.
The Genoa Bypass project aims to streamline the segment of the A10 with the most interconnections with the city of Genoa – i.e., the segment from the toll booth at Genoa West (Port of Genoa) to the town of Voltri – by transferring passing traffic to the new infrastructure, which will be added to the existing infrastructure, effectively constituting an "off-site" upgrade.
Between December 2008 and April 2009, the preliminary design, in order to identify the solution that would best meet local needs, was subject to Public Debate; this was the first case in Italy for a large infrastructural project.
Based on the solution resulting from the public debate, in May 2009, the Final Design was developed and, in 2011, the approval procedure for the Environmental Impact Assessment was initiated.
The Services Conference, held in its first session on 17/10/2014, ended positively in its second session of 22/01/2015.
On 14/04/2015, an Agreement was signed for off-shore construction work between ASPI, ENAC, the Port Authority and Aeroporto di Genova S.p.A. and submitted to MIT DGVCA [Ministry of Infrastructure and Transport - Directorate General for the Oversight of Motorway Concessions] for final approval.
On 27/05/2015, following the signing of the Plan Agreement, the Ministry of Infrastructure and Transport issued the Final Provision, positively concluding the Services Conference, thus finalising the State-Region Agreement for the location of the project.
ASPI adjusted the Final Design to take into account the requirements expressed in the VIA [Environmental Impact Assessment] Decree and in the Services Conference.
The provisions formulated by the Authorities were divided into 114 sub-provisions, of which 38 to be complied with in the Final Design and 59 in the Executive Plan. The remainder concern other phases.
In order to speed up the checks regarding compliance with the provisions, on 09/04/2015, the MATTM [Italian Ministry of the Environment and Protection of Land and Sea] was requested the possibility of carrying out these checks at the VIA [Environmental Impact Assessment] Commission, pending the effective functioning of the Environmental Observatory, established by directorial provision dated 18/06/2013.
Among the provisions related to the Executive Plan, there are some that involve substantial in-depth designs, so as to have an impact on the design phases of the project. For this reason, provisions have been selected which, although compliance is provided for during the Executive Plan phase, must be dealt with as early as during the final design, given that they may have an impact on the project's economic framework.
On 26/04/2016, the Final Design, updated in accordance with the aforementioned provisions, was submitted to the Grantor for approval.
In September 2017, The Decree of the Ministry of Infrastructure and Transport was issued, ratifying the approval of the final design and declaring the project to be of public interest.
