I–27 Numbering Act of 2023

This bill formally designates specific highway segments as Interstate Routes I-27, I-27E, I-27W, and I-27N under existing federal law. It amends the 1991 Intermodal Surface Transportation Efficiency Act to clarify the numbering for routes previously referenced in the law, including segments near Lamesa, Texas, and routes along U.S. Route 287 and U.S. Route 87. The bill makes no new policy or funding changes - it only updates official route designations. This is a technical administrative adjustment affecting highway numbering, not a substantive legislative change.
