Route Naming

In Rhode Island, all numbered state highways should be given the designation "RI-##", where ## represents the highway number (e.g. "RI-24"). These designations should be given as the primary or alternate name for a given segment based on the following rules:

1. If the road is a divided highway, the designation should be the primary name. Any common names for the road should be listed as alternate names.
2. If the segment is considered an urban road, the common name should be the primary name, and the route designation should be the alternate name.
3. If the segment is part of a rural road, the route designation should be the primary name, while the common name should be listed as the alternate name.

Consult the RIDOT Functional Classification Maps to determine where roads pass through urban and rural areas.
