Some Division Design TIP projects will require Signing and Delineation review and/or coordination. The level and type of coordination is based upon several factors such as the location (i.e. interstate projects or freeways), complexity of the project (i.e. CFIs or multi-lane roundabouts), or design elements (overhead structures). Refer to the NCDOT Division Design Projects Signing and Delineation Unit Coordination Requirements for more details (Link).
