Hi Itay Grudev,

The ramps are in fact connected to the motorway (i.e. the asphalt reaches the motorway). The guard rail is placed in such a way since the perpendicular road is not connected to anything yet.

The ramps are tagged with access=no so no router would tell you to use them, even when they are connected. If you really want to show that these ramps are not accessible, you can add barrier=guard_rail to the respective nodes of the ramps. The guard rail is quite visible on Esri imagery.

The noexit=yes tag would be appropriate for roads that have no exit at all for any mode of transit (like the south node of https://www.openstreetmap.org/way/673172027). In this case, there are dirt roads that reach part of the unused perpendicular road.

Happy mapping,
Dimitar
