Hi, https://www.openstreetmap.org/changeset/168580613 removes these name tags. The route relation is already tagged network=US:OH and ref=11, which is sufficient for data consumers to format it as OH-11 if they really want. As far as addressing, the USPS recognizes a number of different formats for numbered highways [1], but “State Route #” is the canonical one per ODOT and county addressing systems.
