python - Is there a way to locally add links to an OSM data set

Here's what I'm trying to do:

• I'm modeling some transportation logistics data


• I want to test the effects of a "new highway" on existing travel demand


• The new road will be created from an arbitrary point (usually not on the existing roadway) to any point on the road network (road line layer)


• The new road should acquire the same fields / attributes as the road it connected too

Is this possible with OSM data?
