The purpose of this legislation is to honor two Arizonans, Kayla Jean Mueller and Charles H. Keating IV, by designating a specific 26-mile stretch of Interstate 17 in Arizona as the "Kayla Jean Mueller and Charles H. Keating IV Memorial Highway." This designation serves to recognize their contributions and sacrifices in the fight against ISIS and in humanitarian efforts. Key provisions of the legislation include the official naming of the highway section between milepost 237 near New River and milepost 263 at the junction with State Route 69 as the memorial highway.
