I-40/US 93 West Kingman Traffic Interchange
I-40/US 93 West Kingman Traffic Interchange
Contents
Construction started in July 2024 on a new system-to-system traffic interchange that will create a free flowing connection between Interstate 40 and US 93 in west Kingman.
Project Description
- New US 93 segment will connect directly to I-40.
- Creates a free-flowing connection between I-40 and US 93 without having to stop at a traffic signal.
- New connection ramps will be constructed at US 93 to maintain access to Beale Street.
- Increase capacity for I-40.
What to Expect During Construction
- Lane restrictions on both Interstate 40 and US 93 are in place from 9 p.m. to 5 a.m. through Friday, Oct. 4. Eastbound I-40: A right-lane closure will be in place near the Stockton Hill Road interchange (mileposts 50 to 51). US 93: Intermittent north- and southbound lane restrictions roughly between Coyote Pass and the I-40/Beale Street interchange (mileposts 70 to 71).
- Year-long closure of Clack Canyon Road started in July. Clack Canyon Road is closed between Longview Avenue and Fort Beale Road, and is open to local residents only.
- Drivers should be prepared to slow down, use caution and expect delays while moving through the work zones.
- Drivers should be prepared for delays of up to 15 minutes.
- Construction-related noise.
Project Purpose and Need
- Address the existing traffic backups and delays on I-40 and US 93.
- Relieve traffic congestion on Beale Street.
- Improve travel between I-40 and US 93.

Design and Construction Timeline
ADOT does not have the funds to build all the improvements of a full system interchange at one time. The project will be constructed in two phases, with the Phoenix to Las Vegas directional ramps constructed first. Phase II will construct the directional ramps between Las Vegas and California, when traffic demands warrant the improvements are needed, and when available funding can be programmed. Phase 1 construction is scheduled to begin in July 2024 and finish in 2026.
History
ADOT has monitored the increasing traffic growth and congestion in west Kingman that has occurred over the years. The traffic volume is more than the current diamond interchange is designed to accommodate.
In 2007, a feasibility study was initiated, and alternatives for a new system traffic interchange were identified. The proposed traffic interchange design includes a free-flowing connection between the two freeways without stopping at the ramp intersection.
The new traffic interchange is being designed to accommodate both current and projected traffic volumes for this area for the next 20 years. The Final Feasibility Report was completed, which identified a preferred improvement corridor.
In 2009, the preferred improvement corridor was further refined into a series of specific alignment alternatives. These alternatives were shared with the public and agency stakeholders where a most favorable alternative was developed. This information was completed and summarized in a Design Concept Report (DCR) in 2015.
The Final Environmental Assessment (FEA) was completed in July 2020.
