Hello demisee,
https://www.openstreetmap.org/way/1238686932 has been mapped as a "police=checkpoint" with a name of "Bus Gate" and a long description.
Are you sure that's correct?  
What I'd suggest that you do is to post a photo of it to the forum https://community.openstreetmap.org/c/communities/uk/86 and ask people there what the best way to tag it is.
Best Regards,
Andy
