All roads lead to Vegas as work begins on $100m Kingman interchange, here's what's happening
Phoenix, Arizona (Release): Work is scheduled to get under way on Thursday, July 11, on a free-flowing interchange connecting US 93 and Interstate 40 in Kingman.
The $106 million project is planned to eliminate delays that can occur for passenger and truck traffic on the main route between Las Vegas and Arizona. While traffic now must stop at a traffic signal where Beale Street intersects with I-40, a system-to-system interchange will feature ramps that allow traffic to flow freely.
Those new ramps will create one new mile of highway between I-40 and US 93, running northwest of the existing interchange at I-40 and Beale Street.
Other project features include:
Widening more than one mile of I-40 in both directions between the new interchange and Stockton Hill Road
Adding a merge lane on US 93 northbound
Widening and/or rehabilitating four bridges on I-40
Building sound walls along a portion of I-40 to the west of Stockton Hill Road
Constructing drainage features
This project is among several underway or planned to improve US 93, which travels 200 miles between Wickenburg and the Nevada line at Hoover Dam. In addition to constructing the Kingman interchange, ADOT's long-term vision calls for a four-lane divided highway through the entire 200 miles between Wickenburg and Nevada. Since 1999, ADOT has completed 19 projects to modernize US 93 between Wickenburg and I-40.
A current US 93 project near Wickenburg is now more than halfway done as work continues to transform a five-mile section of two-lane roadway into a four-lane divided highway. Work on the Wickenburg-area project is expected to continue through this year, with lane restrictions limited to overnight hours to minimize traffic impacts.
ADOT’s Five-Year Transportation Facilities Construction Program for 2025-2029 has these additional projects scheduled to convert segments US 93 to four-lane divided highway: mileposts 106-109.5. in the Cane Springs area; mileposts 190.5-193.5 in the Vista Royale area northwest of Wickenburg; and mileposts 161.7-166.2 in the area of Big Jim Wash.
