I-10 Wild Horse Pass Corridor Construction Updates 
With more than two years since construction began in the I-10 Wild Horse Pass Corridor (I-10 between Phoenix and Casa Grande), project segments are reaching significant milestones. The I-10 Bridges Over the Gila River Project nears its final phase and is expected to be completed in the fall of 2026. The I-10 Gas Line Rd. to South of SR 387 Project is now in full swing, having already surpassed half a year’s worth of active construction. Finally, the I-10 Gila River Indian Community Project is expected to begin active construction this September 2026.
The corridor improvements are being completed as four separate, individual projects and the entire project corridor is expected to be completed by late 2029.
I-10 Bridges Over the Gila River Project
After removing the original eastbound I-10 bridge structure, crews completed construction of the final 16 drilled shafts that will serve as the substructure for the remainder of the new eastbound bridge. Crews constructed piers and pier caps. In May, crews hit a major milestone, placing the last 39 bridge girders for the entire bridge project, and crews are now wrapping up by pouring the bridge deck to tie it into the segment of the eastbound bridge that was completed in April 2025. Construction on the bridge is expected to be completed this fall.
I-10 Gas Line Road to South of SR 387 Project
After six months of active construction including earthwork and grading, motorists traveling through the easternmost section of the project are starting to see the new traffic interchanges at Gas Line Road, Seed Farm Road and SR 387 take shape. Crews have built up the embankments for ramps, clearing areas for widening the roadway, and preparing shoulders for temporary traffic shifts.
Soon, motorists will notice increased activity east of Seed Farm Road as crews begin constructing new travel lanes in the median, making the entire corridor three lanes in each direction. Traffic shifts for eastbound and westbound I-10 in this area are complete. This shift moved traffic to the outside to create a safe workspace for crews near the median so that they can work on that additional travel lane. This traffic configuration is expected to be in place well into next year. Work in this project segment also includes clearing the medians for that additional travel lane and work on culverts for drainage began last month and continues in this segment area.
Finally, temporary shoring installations are underway providing stabilization to existing bridges as well as creating a protective barrier for workers when excavating. A pile driver applies hydraulic pressure to individual sheet piles, driving them deep into the ground.
Please slow down when driving through the work zone. Crews have installed additional 55 MPH speed limit signs at every mile to remind motorists to slow down and maximize safety. Your cooperation helps to make sure you arrive safely at your destinations and keep our crews safe.
I-10 Gila River Indian Community Project
With construction slated to begin for I-10 Gila River Indian Community Project in September 2026, the project team for this segment is finalizing the design and construction plans for the busiest segment of the Corridor. This project is located on I-10 in both directions between the Loop 202 (Santan/South Mt. Freeway) and the Gila River. Planned improvements include adding a third general purpose travel lane in each direction, an HOV lane between Loop 202 and Riggs Road in each direction, improved interchanges at Wild Horse Pass Blvd., SR 347/Queen Creek Road, and Riggs Road, a new interchange at Koli Road and an updated bridge over I-10 at Goodyear Road.
Project Team Profile: Julie Gadsby, PE, ADOT Construction Manager
Julie Gadsby has successfully managed several of ADOT’s most complex, high-profile highway projects. Now, she brings nearly three decades of experience to her current role as Construction Manager for the I-10 Wild Horse Pass Corridor Project, one of the state’s largest highway improvement efforts. 8
Julie began her career with ADOT as an Engineer in Training at a time when few women were working in construction. Over the years, Julie learned that “boots on the ground” and real-world experience are the keys to success. She steadily advanced her career from Transportation Engineering Specialist to the Assistant District Engineer for the Central Division, and now serves as Construction Manager for ADOT’s Alternative Delivery and Major Project Division.
During her tenure, Julie oversaw the completion of the new $1.6 billion dollar Loop 202South Mountain Freeway and the $850 million dollar I-10 Broadway Curve Improvement Project.
Each large-scale transportation project brings its own unique set of challenges to the management team and Julie’s extensive experience is instrumental on the I-10 Wild Horse Pass Corridor Project.
“This project will be the first project that I have worked on for the Department where you are not allowed to close mainline in order to complete overhead bridge work,” Julie said. “It will require the project team to be innovative in order to get the work done safely within the allotted time frame.”
One of the project components includes adding an additional general-purpose travel lane in each direction from Loop 202 to the Gila River. These lanes will be constructed in the median, while maintaining the same number of travel lanes throughout the construction process.This approach minimizes impact on motorists and preserves access to and from the highway during the construction.
Julie has gained respect as one of the most experienced transportation construction managers working in Arizona. She’s also known for mentoring others, sharing her extensive knowledge regarding policies, processes and procedures with young engineers and construction managers. She has mentored and trained numerous participants in the department’s Engineer in Training program, helping men and women build strong foundations early in their careers.
Julie is quick to point out that being a construction manager for major highway projects is not easy. It requires dedication, adaptability and the ability to work with a wide range of personalities. She believes that successful project delivery depends on building the right team and responding quickly to diffuse challenges.
When asked what advice she’d give to aspiring transportation engineers and construction managers, Julie emphasizes the importance of balancing formal education with experience.
“Straight out of college you think you know everything but over the years the craft that actually build the jobs have shown me a degree only scratches the surface,” Julie said. “Construction managers act as the critical bridge between the Department and Industry. You cannot manage what you do not understand.”
“It has been a very rewarding job, but it demands high adaptability, long hours, and strong thick-skinned leadership,” Julie added.
After nearly 30 years on the job, Julie has not only helped to build Arizona’s highways, but has also built a solid reputation as one of ADOT’s strongest leaders.

ADOT DBE & Small Business Expo
On May 12, members of the I-10 Wild Horse Pass Corridor project team represented ADOT Major Projects at the ADOT DBE (Disadvantaged Business Enterprise) & Small Business Expo. This was the largest expo that ADOT has held for small businesses and there wasn’t a moment where we weren’t busy sharing information and answering questions about the project. If you represent or work for a small business and are interested in learning about opportunities to work with ADOT, please check out the ADOT Small Business and Workforce Development website.
Chandler Rotary Club Presentation
On May 21, the I-10 Wild Horse Pass Public Involvement Team was invited to present at the Chandler Rotary Club. The team shared information about the project with club members and small business owners. Members of the Rotary Club were very engaged and showed interest by asking many detailed questions about the project’s construction work components and project timeline. The group expressed their appreciation for the improvement project and asked us to come back again for another update next year. If you’re interested in having the team come speak with your clubs, organizations or agencies, please reach out and send a request on the project website.
