Unable to answer "What type of barrier is this?" for https://osm.org/node/6139338842 via StreetComplete 53.1:

It's not a bicycle barrier, but is?

The middle section has disappeared.

Even if it were reinstated, it's made large enough that bicycles can get through without dismounting, so the other questions don't make sense.
