There are several steps that must be completed before a project ever goes to construction. NCDOT also works with partners at the local, state and federal levels, as well as utility companies and landowners. Some examples of what could necessitate a change in schedule include design modifications, funding or property acquisition taking longer than expected. The STIP can be changed by administrative modifications or amendment.
Amendments require approval by the N.C. Board of Transportation and the U.S. Department of Transportation, as well as any affected Metropolitan Planning Organization.
Local planning organizations agree to the projects within their jurisdiction and approve their local STIP. If the local planning organizations agree to and approve the change to their local STIP, the N.C. Board of Transportation would then need to approve the change and submit it to the state legislature for information.
The U.S. Department of Transportation would give final approval on the change.
