The road has been closed to traffic (motorcycles seem to be getting through) outside 555 Bar. Reason being roadworks. No idea how long this closure will be. A big pain in the backside for me .
I will post again when it opens again - not too long I hope.
There's a workaround. Going east on 94, turn left just before Souay Vista. The 3rd soi you come to is a T intersection, go right to join the 94-88 link road.
Reverse is easy. Going south on the link road, turn right at the last soi before the closure. Turn left at the first soi. Straight to the T intersection at 94.
If one prefers pictures, the sois described are on the soi 94 map.
