s the closed Tintern/Chepstow road passable on a bike? I could do with avoiding any proper hills as MrsIHN is currently recuperating from a leg op.
Dunno if A466 is passable by bike and don’t have time to do another recce this weekend.
Bare in mind that even if passable it requires a climb of 150m. The ncr42 route up the Angiddy valley is 200m. In your circumstances I wouldn’t want to risk climbing up the A466 only to have to turn around and go back to Tintern, if the route is blocked. It sounds like they’re doing some pretty serious work up there, so fare chance you might not be able to get through.
