Is there a standard way to show basic informations about ferries, bridges, roads, that are vailable only periodically? Especially in the German version of the map, that hides a lot of additional informations.

Special reason for my question: There is a lifting bridge, which is used by a grand touristical cycling route, but in lifted state most of time. It is available for the public (only cyclists and pedestrians) only in eight hours of each weekend of five months. That’s all, there is no on-demand-service.

How about http://wiki.openstreetmap.org/wiki/Key:opening_hours
