The United States has a significant number of highway networks, especially at the state and local level, which are not easily translated into network=* and ref=* values on their route relations. This page catalogs those networks and provides links to community discussions regarding the tagging of those networks.

- ↑ Indicates whether or not the ref is listed on the sign verbatim. Routes listed as "Initialism" have ref values derived from names listed on signage but do not have the initialisms as a standalone increment of text.
- ↑ The shield only appears on mile markers frequently posted along the roadway. The route is prominently identifiable on wayfinding signage but not using the shield.
