There are to my knowledge four barriers where motor vehicles can't pass along Arbetaregatan: Two where Källådersgatan and Loftgatan intersect. One just after Strömgatan, the one you claim is wrongly mapped. One just north of Sandgårdsgatan. All are tagged with motor_vehicle=no. 

See [this Mapillary street view](https://www.mapillary.com/map/im/elI3AVwPWYigyw9aUrbE5f) for confirmation of the location of the barrier near Strömgatan, taken in September this year. If they've installed additional ones or moved them since then please provide more up-to-date or accurate info on the placement and I will correct it.
