An amendment is defined in 23 CFR § 450.104 as "a revision to a long-range
transportation plan, TIP or STIP that involves a major change to a project included in a
metropolitan transportation plan, TIP or STIP, including the addition or deletion of a project
or a major change in project cost, project/project phase initiation dates, or a major change in
design concept or design scope (e.g., changing project termini or the number of through traffic lanes).
Changes to projects that are included only for illustrative purposes do not require an amendment.
An amendment is a revision that requires public review and comment, redemonstration of fiscal
constraint, or a conformity determination (for metropolitan transportation plans and TIPs
involving "nonexempt" projects in nonattainment and maintenance areas)."
