The 40 days of closure of the Monte Galletto Sinistra tunnel, on the A7 until April 9, are causing damage of around 25 million to road hauliers. Thus the account of 316 million of the Ligurian chaos rises from December 2019 to July 2020. Also considering all the other activities, we arrive at the billion requested by the main economic categories of Liguria, Confindustria and the Genoa Chamber of Commerce at the head, the Ministry of Infrastructures (Mims). It will not end here: the decades-long degradation of the highways requires a decade of construction and inconvenience.
The rosary of construction sites
Unavoidable sacrifices, mitigated by modulations in the works: we leave the emergency of the sudden closures imposed by the 2020 inspections and enter the phase of “real” construction sites. Which will also be suspended in the tourist season whenever possible. And now Aspi (Autostrade per l’Italia) has a monitoring system shared with Mims that sets state-of-the-art standards. In Liguria, Aspi will spend about 2 billion in this decade and so far, in galleries alone, it has spent 173 million. Between now and the end of the year, the interventions will be concentrated in the A26, while in the A7 the significant inconveniences are about to end; A10 Genoa-Savona and A12 Genoa-Sestri Levante will go down.

But new fronts are opening up on the rest of the network, managed by Astm (Gavio). On the A10 Savona-Ventimiglia there are adjustments and inspections in the tunnels and in May we will start with the anti-seismic adaptation of the viaducts. The replacement of safety barriers continues (for 138 million), which is about halfway through and with an expected end by 2028.
Until then there is a risk of Mims measures: paradoxically there is no full legal obligation to change the barriers prior to 1992, but the ministry, to reduce the risk of failure in the event of a truck collision, can impose very low speed limits. to heavy vehicles on stretches that overlook inhabited areas or other roads (this is also the risk in Sicily).
Construction sites also create risks in built-up areas: on Tuesday, due to the wind, parts of the scaffolding fell from the Bisagno viaduct of the A12. Pavimental (Aspi) terminated the contract with the company that was carrying out the work.
