The Autostrada A26 is an autostrada (Italian for "motorway") 197.1 kilometres (122.5 mi) long in the northwestern Italian regions of Liguria and Piedmont. It is named the Autostrada dei Trafori ("Tunnels Motoway") after the numerous tunnels through which it passes, both Apennine and Subalpine. It runs northwards from Genoa on the Ligurian coast, over the Apennines, and across the wide plain of the Po valley to the environs of Lake Maggiore and the mouth of the Val d’Ossola. In addition to this ‘main trunk’ of the road, there are three side branches, also of motorway class which function as link roads between the A26 and the A7, the A4 and the A8. The A26, together with these link roads, is managed by Autostrade per l'Italia S.p.A.
The A26 begins from the Genoese town of Pra', which lies on the coast to the west of the city centre. (Note that the gate of Pra' is still wrongly named "Voltri", nevertheless, Voltri has anything to do with the motorway gate and that the City of Genova has formally asked for the change of its name in "Gate of Pra' "). It crosses the Apennines at the Passo del Turchino (532m) and passes through Ovada. Near Castelferro (frazione of Predosa) an eastern branch, the Autostrada A26/A7, provides links to Novi Ligure and to the Autostrada A7 (Genoa – Milan) which it joins near Spineto Scrivia, to the south of Tortona.
The Autostrada A7/A26 Diramazione Bettole-Predosa (A7/A26) is a 17 km motorway which links the A26 near Predosa with the Autostrada A7 near Bettole (a frazione of Pozzolo Formigaro). The entire autostrada is within the Province of Alessandria. Its sole exit is for Novi Ligure and it provides a convenient means of access to both the A7 and the A26 from that town.[1]
