In 2022 FHWA issued a final rule, which will allow State DOTs to adopt procedures or design criteria, as approved by FHWA, that enable the State to undertake resurfacing, restoration, and rehabilitation (RRR) projects on freeways, including Interstate highways. Freeway facilities follow the same 3R principles and analyses in this chapter. However, a design exception or design waiver would be needed if the respective 4R freeway minimum criteria (as specified in App. A, or App. B) are not met or not intended to be met. A benefit-cost evaluation would again serve as the basis for any needed design exceptions or design waivers.
