Quick update. The road repairs in the Roya valley are progressing well, updates available here
Some sections are on a 1-way alternating system.
The re-route needed to navigate the Tende area damage isn't as dramatic as I thought it may need to be. The shorter way off the Tende down the switchbacks is out for now, sadly. The Via del Sale section is now the standard route rather than a longer option and other options before and after it will shorten the route if needed. It's worth it though, a real highlight of the route -
In the Roya valley the lower section of the old route to the Fort de la Forca is closed, revised route goes up an alternative road to reach the same gravel track for the last 9km or so to the Fort de la Forca. It's still a big climb with 1700m gain and the new road section looks more than ok -
New route collection due onto komoot soon, new route cards and DIY TNR patches available late June onwards.
