the road segment should only be split in cases like a bridge out, or where the surface has been removed (which is not the case here), or perhaps been completely buried under an earthen wall for economic reasons.  in the latter cases, there will often be an impromptu path created over tine from use between the two segments suitable for foot and simple vehicle (cycle) traffic.

In this particular case, select vehicles appear to be able to pass the mapped barrier.  Whether they are legally allowed is something I cannot infer from the aerial imagery, but it looks to me that bicycles, which in my location (rules may differ here) are forbidden from using pavements after a certain rider age, can easily go around the barrier, which i would call not just bollards, but also a kerb.

Even if the free width may make it precarious for an uncoördinated rider to pass to the side, it is certainly possible to dismount and pass walking the cycle, provided it is not too heavy or widely packed, between the posts.

The same appears true for rollers, skateboards, Mofas, and perhaps for motorcycles, for some of which a legal limitation, not visible from the aerials, may restrict them, and that tagging, when known, should apply to the barrier.

Further, where I am, pedestrians are permitted to use all roads save for signed motorways and Autobahnen, unless otherwise signed, and certain rules that often apply to me require me to cede the pavement and walk in the street.  Other pedestrians may have difficulty navigating kerbs, which around me can be nearly 30cm which even i have difficulty conquering in me old age, so plenty of OAPs can be seen in their mobility scooters or zimmer frames on the road proper.

For all of able-bodied pedestrians, horses, and off-road bikes, I do not see the additional kerb as well as the bollards posing an insurmountable challenge any more than the other mapped barriers I have difficulty navigating with a fully-loaded pushbike.

By creating a gap in the road, if it were to be near me you would be breaking cycle routing which i am guessing was not the intent of the planners who ordered the barrier to be installed, as I often have seen comparable designated free space to the side of a motorised-vehicle-barrier, specifically set aside for cycles even though it falls briefly far under the minimum two-metre width required legally to allow riding.

much of what i write is edge cases, made more difficult by this being not just a simple row of bollards, but also what i would categorise as a kerb.  also, my interpretation is skewed by my local rules, most of which may not apply in this country where this mapping is taking place.  and most such edge cases are beyond what osm maps, where i would refer to reality rather than what appears on a map rendering.

personally, if i were to map this, i would micro-map each individual bollard as well as the kerb, although the mapbox aerial imagery was deliberately degraded in resolution some time ago and no longer appears in the sharp detail of the original, where now are blocky pixels.  this is far beyond your business-oriented mapping, and does nowt to help routing based on the schematic line of the road and the single point representing the barrier area, but may help someone studying the map to decide if a heavily-loaded long cycle trip is do-able along here.

sorry for the long-winded reply.  i hope something in it makes sense.

cheers!
