The Arizona Department of Transportation (ADOT) reports that construction on a new Interstate 40 interchange in east Kingman has reached the one-third completion mark. The Rancho Santa Fe Parkway interchange, which aims to improve access to the area near Kingman’s airport, is expected to open by mid-2026.
The project, valued at $44 million, began in December 2024 and is being carried out in collaboration with the City of Kingman. As part of the partnership, the city will separately build the new Rancho Santa Fe Parkway north of I-40 to connect with Kingman Airport. The location of the new interchange is approximately four miles east of the current Historic Route 66 interchange at Andy Devine Avenue.
According to ADOT, significant progress includes widening I-40 bridges over Rattlesnake Wash and completing a westbound detour necessary for constructing two bridges that will carry Rancho Santa Fe Parkway over I-40. Work on an eastbound detour is nearly finished and is anticipated to be operational by the end of August.
Additional improvements as part of this project include installing sidewalks, curbs, gutters, pipe culverts, concrete box culverts, storm drainage systems, traffic signals and lighting. The project also involves adding fencing, guardrails, signage and pavement markings.
Construction activity is scheduled for both days and nights from Monday through Thursday, while work on Fridays will occur only during daytime hours. ADOT states that two lanes will remain open in each direction on I-40 throughout construction; however, drivers may experience delays up to 20 minutes during certain phases.
“Once the detours are in place,” ADOT advises drivers “to use caution around construction vehicles exiting I-40 into the median to construct the new bridges.”
