I-40: Rancho Santa Fe Traffic Interchange

I-40: Rancho Santa Fe Project Map

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 in early 2022.

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). 

Overview

  • Construct a new traffic interchange on I-40 at milepost 57.
  • Construct a four-lane street along Rancho Santa Fe Parkway, north of I-40, between I-40 and Santa Rosa Drive.
  • Construct a four-lane street along Rancho Santa Fe Parkway, south of I-40, between I-40 and Louise Avenue.This section will include bicycle lanes, sidewalks, curb and gutter and a center raised median.

City of Kingman

  • Construct a two-lane street along Rancho Santa Fe Parkway, north of I-40, between Grand Canyon Road and Industrial Boulevard, near the Kingman Municipal Airport.

What to expect during construction

  • Work will take place during daytime hours.
  • I-40 traffic will be detoured on the future Rancho Santa Fe interchange ramp alignment while crews construct the new bridges over Rancho Santa Fe. 
  • Two travel lanes on I-40 will remain open in each direction.
  • Motorists should be prepared for delays of up to 15 minutes.
  • The speed limit will be reduced in the work zones.

Schedule 

Planning is underway for construction to begin in early 2022 and be completed in late 2023. More information will be posted prior to the work.

Schedule subject to change based on weather or other unforeseen factors.
