If it was a motorway, it would have an "M" classification, like the nearby M77.
Not being a motorway does not mean, however, that cycling is always allowed on a road. The official term for motorways is "special roads" and there are a few special roads which do not have M classification. AFAIK, at least part of the A55 in North Wales is a special road. Otherwise, cycling can be banned on a road by the use of a traffic regulation order (TRO) which would be made clear with NO CYCLING signs.
