I-40: Rancho Santa Fe Traffic Interchange

I-40: Rancho Santa Fe Traffic Interchange


The Arizona Department of Transportation, in coordination with the city of Kingman and the Federal Highway Administration, is planning for construction of a new traffic interchange, the Rancho Santa Fe Traffic Interchange on Interstate 40 (Exit 57), in east Kingman.

The purpose of this project is to provide access and accommodate future traffic volumes generated in the rapidly-growing east Kingman area, and to relieve congestion at the existing East Kingman interchange (Andy Devine Avenue/State Route 66, Exit 54).
