My tour planned on Komoot was necessarily interrupted, because the map is not up to date.  The track of the section of my tour (in which the Komoot legend indicates a Road for local traffic) is as follows:  https://www.komoot.com/it-it/plan/tour/d08Am0swQCCbfk=FNcABPcj60NuWslA/@40.7084264,8.5473816,15.733z  . 
 The short tunnel under the ss.131 highway (40.709145, 8.547533) has been closed for years and if,  beyond the tunnel (40.709003, 8.547248), you try to reach the Monserradu local road up to point B (40.703605, 8.545138), first the the trail is bumpy, then disappears into an overgrown field, and is finally swallowed up by the woods, where the GPS finds no signal. Locals say the road had been planned but never built !
