Given that this stretch mainly consists of RIRO junctions, this would be considered a borderline case as outlined in this wiki article: http://osm.wiki/United_States/2021_Highway_Classification_Guidance#Exceptions_and_Borderline_Cases

Because of this, this stretch of Central shouldn't be changed from its current classification without consultation with the local community. I ask that you please revert these changes until consensus is reached with the community.
