Hi dsm, please do not use TIGER as a source for road names in Utah, it is very inconsistent about how it handles them. For more information about our unusual road names and how the local community has settled on handling them check out https://wiki.openstreetmap.org/wiki/Utah/Naming_Conventions . If you have any group resources at Mapbox, please make sure this is part of it as this is not the first time I've had to point this out to your team.
