Note that the routes as defined by the state may not always match 
signage for various reasons. For example, SR-900 and SR-901 are not 
signed, and the data likely does not include overlaps such as US 50 on 
I-15. It may be easiest to use the Overpass API to download all ways in 
the state with ref tags and all relations with network=US:UT and find 
any ways with SR or UT that are not part of a relation.
