PHOENIX – The westbound Loop 202 (Santan Freeway) on-ramp at Val Vista Drive in the Southeast Valley is scheduled to close for approximately 60 days starting at 10 p.m. Friday, March 14. The closure will allow crews to reconstruct the ramp as part of the Loop 202 widening project in Chandler and Gilbert.

Drivers should consider using the westbound Loop 202 on-ramps at Santan Village Parkway or Lindsay Road while the entrance ramp at Val Vista Drive is closed.

The $200 million Loop 202 Improvement Project is adding lanes and interchange improvements along 8 miles of Loop 202 between Loop 101 (Price Freeway) and Val Vista Drive in Chandler and Gilbert. The project was featured in a recent episode of the On the Road with ADOT podcast, which is available at azdot.gov/podcast or through podcast platforms including Apple Podcasts and Spotify. 

This project is funded in part by Proposition 400, a dedicated half-cent sales tax that Maricopa County voters approved in 2004. The project is scheduled under the Regional Transportation Plan managed by the Maricopa Association of Governments, the metropolitan planning organization for the Greater Phoenix region.

KINGMAN – A project to construct a free-flowing interchange between Interstate 40 and US 93 is quickly transforming the landscape along I-40 in this northwest Arizona community, with crews clearing land for new travel lanes, removing sound walls and preparing the foundations for new bridges.

This progress comes six months into the Arizona Department of Transportation’s $106 million project to eliminate delays that can occur for passenger and truck traffic on the main route between Las Vegas and Arizona. Instead of traffic stopping for a traffic signal on Beale Street at I-40, a mile of new ramps will allow traffic to flow freely between I-40 and US 93.

Some of the most visible progress on the I-40/US 93 interchange project is along a golf course west of Stockton Hill Road, where crews have leveled a slope to allow for new travel lanes. Further west, crews have drilled eight shafts needed to widen the existing Clack Canyon Road bridges. And the site of a new Beale Street overpass has been excavated, with a concrete foundation now in place.

As construction continues, the public can expect daytime and nighttime work, rock crushing operations in the work area and short closures of US 93 for rock blasting. ADOT is maintaining two lanes of travel in each direction during peak travel times, with lane restrictions limited to off-peak hours. Drivers are able to continue exiting both US 93 and I-40 at Beale Street to access businesses, Route 66 and downtown Kingman.

Construction is expected to continue into 2027, when the interchange will open with 6 miles of widened or newly constructed roadway. The project includes five new bridges, two bridge widenings, four bridge rehabilitations and two miles of sound walls. 

The project is creating a mile of new highway carrying traffic northwest of the existing interchange at I-40 and Beale Street. Other features include:

• Widening more than a 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

The interchange is designed to handle projected traffic growth for the next 25 years.

PHOENIX – An Arizona Department of Transportation project that constructed Loop 303 interchanges at 43rd and 51st avenues near Interstate 17 has been named a top 12 finalist in the 2024 America’s Transportation Awards competition.  

This designation makes the $70 million Loop 303 project eligible for two different honors: the Grand Prize and the People’s Choice Award. The competition is sponsored by AASHTO, an association representing highway and transportation departments nationwide, as well as AAA and the U.S. Chamber of Commerce.

Through Oct. 29, you can vote once daily for the People’s Choice Award by visiting americastransportationawards.org. The Grand Prize will be decided by an independent panel of transportation experts. Both awards will be presented at AASHTO’s annual meeting in Philadelphia.

ADOT partnered with the Maricopa Association of Governments (MAG), the regional transportation planning agency, and city of Phoenix to accelerate construction of the Loop 303 bridges and ramps to address current and future traffic growth near the Taiwan Semiconductor Manufacturing Co. plant in the north Valley. The interchanges were completed in September 2023, several years sooner than originally planned.

“With a large semiconductor manufacturing facility under construction, these two interchanges are connecting Arizonans and empowering our state’s economy,” ADOT Director Jennifer Toth said. “This collaboration with the Maricopa Association of Governments and city of Phoenix also supports continued development and growth of businesses and services, including health care and housing.”

Earlier this year, the project earned a West Region award in the America’s Transportation Awards “Quality of Life/Community Development, Medium Project” category among state departments of transportation.

Construction of new Loop 303 interchanges at 43rd and 51st avenues was funded through the dedicated Proposition 400 half-cent sales tax approved by Maricopa County voters in 2004. The project is part of the Phoenix area’s Regional Strategic Transportation Infrastructure Investment Plan managed by MAG.

The new interchanges were designed to help manage future transportation needs in the area, support the Phoenix area’s growing semiconductor footprint and its supply chain, and allow for community development, including businesses and services. 

ADOT manages the construction and maintenance of nearly 7,000 miles of state highways, including Phoenix-area freeways. Project information is available at azdot.gov/projects. 

PHOENIX – A recent Arizona Department of Transportation project that constructed Loop 303 interchanges at 43rd and 51st avenues near Interstate 17 is a winner in the 2024 America’s Transportation Awards competition that includes a focus on community development.

The $70 million Loop 303 project earned a West Region award in the “Quality of Life/Community Development, Medium Project” category in the national competition among state departments of transportation. The competition is sponsored by AASHTO, an association representing highway and transportation departments nationwide, as well as AAA and the U.S. Chamber of Commerce.

KINGMAN – The State Transportation Board has awarded a $106 million construction project to build a free-flowing traffic interchange for Interstate 40 and US 93 in Kingman.

With the contract awarded to Fisher Sand & Gravel Co. during the board’s meeting on Friday, March 15, construction is expected to begin this summer and take two and a half years.

The interchange in west Kingman is designed to reduce congestion on the highly traveled route between Phoenix and Las Vegas while improving safety, travel times and reliability. While vehicles now must stop at a traffic signal where Beale Street intersects with I-40, the system-to-system interchange will feature ramps that allow traffic to flow freely.

The interchange is designed to handle projected traffic growth for the next 25 years.

PHOENIX – Drivers in the West Valley can now use the second I-10 Diverging Diamond Interchange (DDI) to be constructed as part of the Arizona Department of Transportation’s ongoing freeway widening project in the Buckeye area.

Crews reopened the I-10 interchange at Watson Road today (Thursday, April 27). The interchange has been reconstructed using the diverging diamond design, which has grown in popularity across the country for safety and traffic flow benefits.

Diverging diamonds allow the two directions of cross-street traffic traveling over or under a freeway to shift to the opposite side of the roadway. The crossing is designed to improve the overall movement of traffic and enhance safety by limiting potential traffic conflict points and allowing direct left turns onto a freeway entrance ramp. Drivers avoid waiting at a traffic signal and don’t cross in front of opposing traffic when making those left turns.

ADOT continues work to widen 8 miles of I-10 from two to three lanes in each direction between Verrado Way and State Route 85. The entire $82 million I-10 improvement project, which was launched in July 2021, is on schedule for completion this summer (2023).

The I-10/Watson Road interchange is the fourth full diverging diamond to be added along the state’s highway system. The nearby DDI at Miller Road opened in Aug. 2022 as part of the I-10 widening project. DDIs also have been constructed at I-17 and Happy Valley Road in north Phoenix and along I-10 at Houghton Road in the Tucson area. Two smaller diverging diamonds also are in use along the Loop 202 South Mountain Freeway in Phoenix.

ADOT works in partnership with the Maricopa Association of Governments on the planning and construction of new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region. Projects are funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004.
