The driver reported that it was impossible to travel along this road. Perhaps this is a service road for maintenance or there are restrictions (barriers) on the road. Can anyone confirm?

Is this service road a through-road? Marked as a cul-de-sac at the western end.

there's no passage under the motorway here, but it seems so from the map
