There is no roadblock here anymore, just cameras indeed, and signage. Access limitation for motor vehicles is already registered in OpenStreetMap: https://www.openstreetmap.org/way/480032809 and has an effect on navigation: https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=52.16551%2C5.43100%3B52.16504%2C5.43001
The cameras and signs are also in the database.
