Rivarolo II tunnel between A12 and A7 closed due to serious deficiencies. Fears of relapses after reopening to travel between regions
The chaos on the Genoese motorway network has not subsided after the closure in recent weeks of twenty tunnels results «at risk» inspections carried out by Aspi in collaboration with the Ministry of Transport and Infrastructure.
Yesterday morning another check ended with a disturbing result. Even in the gallery “Rivarolo II” missing from the vault eighty percent of expected concrete. Thus the closure of the tunnel was triggered, adding to that of the twin “Rivarolo III”, which had already been stopped for a few days for the same problems. Aspi, therefore, could not help but close the connection in both directions between A7 and A12. In practice, you cannot reach the Genova Ovest exit from Genova Est and vice versa. And you can’t get to the latter exit from Milan. To do this you must go out to Bolzaneto and return to the highway or continue on ordinary roads.
The low weekend traffic (heavy vehicles do not circulate except for exceptional reasons) did not cause any particular traffic problems yesterday. And yet there is utmost concern for tomorrow when the actual traffic will restart (Wednesday 3 June the reopening of the regions is also fixed).
There is the risk of blocking circulation in the affected stretch and for this reason both the local police and the road police have already been alerted.
For the moment Autostrade has not provided a precise date for the reopening of Rivarolo II but highlights how in this period “traffic on the Genoese routes has never exceeded 50 percent».
Dal MIT indicate that the tunnel, precisely in light of the type of intervention requested, «it should not open before Wednesday». So much so that the super commissioner of Mit Placido Migliorino worried about the results of the inspection in “Rivarolo II” decided to hurry back to Genoa (he had left just last Thursday) already this afternoon for an extraordinary check. On the same day, Migliorino met Aspi executives on Friday to take a look at the verification activity in the galleries in Liguria. And he highlighted the need to recheck 100 galleries of the Genoese section “why need more thorough inspections compared to what has been done so far, “explains the Commissioner.
Reels in practice after the collapse of the Bertè gallery (on December 30, 2.5 tons of rubble broke away from the vault, threatening to provoke a new tragedy) it checked 240 tunnels of the Genoese network out of 285. According to what is revealed by the MIT, only 45 would be missing. But the commissioner (which imposed a special on Aspi control method through coringi) noting concrete problems in several tunnels, he sometimes asked the concessionaire to repeat the checks in another hundred tunnels “. There is therefore a risk that the number of closed galleries in Genoa in the coming days may rise further.
Aspi in a note underlines how the intervention on the Rivarolo III tunnel (the twin of the one closed yesterday) will end on Wednesday with the reopening to traffic. And he adds that construction defects were found inside the two galleries.
Aspi: «shared interventions»
As regards, however, the new inspections on tunnels, Autostrade explains “that it shared and approved with the Mit the inspection model proposed at the end of 2019”. “The technical offices – he adds – have asked to speed up the verification programs to 30 September, highlighting the need to anticipate the disassembly of the hydraulic coatings (the corrugations) in about 100 tunnels until 30 June”. To achieve this, Aspi created a task force first of 500 and then 800 skilled workers. “The goal planned this week with the top management of the Mit – concludes Autostrade – is to limit the inconvenience as much as possible viability thanks to a shared plan that Minister De Micheli himself declared to be substantial for safety. For inconvenience to users there are discounts on tolls “.
