Is there any way to force a route calculation through a street, even if the route engine interpretes the street as impassable (e.g. due to road works, etc.).
For normal route planning you could use the
skip_segments feature and add a waypoint right before and after the impassable segment.
In general however you could only do that by setting up your own openrouteservice backend and adjust it accordingly.
But if there is no construction work going on anymore, adjusting the data would also be an option. This will however take 1-2 weeks to be considered.
