23:1.0.1.5.13.1.1.9.16 : Appendix B
Appendix B to Subpart A of Part 470 - Designation of Segments of
Section 332(a)(2) Corridors as Parts of the Interstate System
The following guidance is comparable to current procedures for
Interstate System designation requests under 23 U.S.C.
103(c)(4)(A). All Interstate System additions must be approved by
the Federal Highway Administrator. The provisions of section
332(a)(2) of the NHS Act have also been incorporated into the ISTEA
as section 1105(e)(5)(A).
1. The request must be submitted through the appropriate FHWA
Division Office to the Associate Administrator for Program
Development (HEP-10). Comments and recommendations by the division
and regional offices are requested.
2. The State DOT secretary (or equivalent) must request that the
route segment be added to the Interstate System. The exact location
and termini must be specified. If the route segment involves more
than one State, each affected State must submit a separate
request.
3. The request must provide information to support findings that
the segment (a) is built to Interstate design standards and (b)
connects to the existing Interstate System. The segment should be
of sufficient length to provide substantial service to the
travelling public.
4. The request must also identify and justify any design
exceptions for which approval is requested.
5. Proposed Interstate route numbering for the segment must be
submitted to FHWA and the American Association of State Highway and
Transportation Officials Route Numbering.
