Schedules are subject to change due to inclement weather or other factors. ADOT plans and constructs new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region. Most projects are funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004.

Real-time highway conditions are available on ADOT’s Arizona Traveler Information site at az511.gov, the az511 app or by calling 511.

TUCSON – Some of the most visible work to rebuild a section of I-10 in the Tucson area is quickly progressing as work crews have now set more than 80 bridge girders in place and installed large sections of the new concrete driving surface.

Work is now 40 percent complete on the Arizona Department of Transportation’s project to reconstruct and widen I-10 between Ina and Ruthrauff roads, with work starting just less than one year ago.

A key element of the project involves placing 217 girders for nine new bridges, and most of those girders along I-10 will be set by the end of March. Meanwhile, work crews have completed 80 percent of concrete paving work and are now turning to concrete drainage features and barriers.

That concrete barrier work is key to a future milestone that will return drivers back to I-10 itself rather than using the current detour along frontage roads. Once the barrier work is complete by late summer, westbound and eastbound I-10 traffic will shift to the reconstructed freeway lanes.

When traffic returns to I-10, crews will then focus on finishing the Orange Grove Road interchange, which is expected to reopen in late 2024. 

After that, work shifts to the Sunset Road interchange. As part of that interchange work, ADOT will construct a project funded by Pima County that will extend Sunset Road east to River Road with new bridges over the Union Pacific Railroad tracks and the Rillito River.

The overall project will continue through late 2025, when the Sunset Road interchange will reopen.

ADOT will maintain access to local businesses throughout the project.

Other project improvements include:

• Rebuilding the Orange Grove Road bridges to allow for higher clearance
• New Orange Grove and Sunset road interchanges that will feature additional lanes on entrance and exit ramps to promote safety and reduce delays
• Replacing all nine bridges in the project area, including those over Canada del Oro Wash and Rillito River
• Constructing an access path to the Chuck Huckelberry Loop from Sunset Road
• Related work on lighting, landscaping and drainage

The I-10 project is part of the Regional Transportation Authority’s roadway improvement plan, managed by the Pima Association of Governments.

PHOENIX – The Arizona Department of Transportation will hold a virtual public meeting on Tuesday, Jan. 23, to provide information, gather comments and answer questions about designs to improve the Interstate 10 interchange at Jackrabbit Trail in the Buckeye area.

ADOT’s virtual meeting is scheduled as follows:

• 6 to 7:30 p.m., Tuesday, Jan. 23 
• Participants can register online at azdot.gov/JackrabbitMtg
• You also can use the call in number: 669.444.9171 Participant ID: 264911
• English Webinar ID: 951 5167 6868  Spanish Webinar ID: 948 3052 6118

Planned improvements include:

• Reconstructing the I-10/Jackrabbit Trail interchange and adding traffic signals.
• Widening on- and off-ramps and providing additional turn lanes.
• Widening Jackrabbit Trail to three lanes in each direction between McDowell Road and Van Buren Street.

The project to improve traffic flow and safety at the Jackrabbit Trail interchange is not currently funded for construction. This project is included in the Regional Strategic Transportation Infrastructure Investment Plan.

The virtual meeting will include a presentation by ADOT’s project team and an opportunity for questions and comments from participants. Following the meeting the presentation will be available on the project’s study website at azdot.gov/I10Jackrabbit.

Public comments about the draft recommended improvements at I-10 and Jackrabbit Trail can be submitted through Feb. 7 in the following ways: An online survey at azdot.gov/i10JackrabbitComments; by phone at 623.695.7411; by mail at ADOT Community Relations, 1655 West Jackson St., MD 126F, Phoenix, AZ 85007 and by email at [email protected].

TUCSON – Major improvements are in the works for those who use Interstate 10 in the Tucson area, where new lanes and a rebuilt interchange are on track to open by the end of the coming year.

Motorists can expect a year of many changes as part of the ongoing project to widen I-10 between Ina and Ruthrauff roads. It’s one of several significant projects the Arizona Department of Transportation has planned for southern Arizona in 2024. 

Some highly visible progress on I-10 will begin early in the year as crews place 121 girders for nine new bridges, along with concrete paving for the rebuilt section of freeway.

And while heavy construction will dominate the 4-mile segment of I-10 during the year, it will come with a big payoff. By late 2024, ADOT will shift traffic onto a reconstructed freeway featuring four lanes of traffic in each direction. And the Orange Grove Road interchange will reopen with wider entrance and exit ramps to promote safety and better traffic flow.

The $171 million I-10 project will continue into 2025, when a reconstructed Sunset Road interchange opens. The interchange will feature a connection eastward to River Road thanks to a new bridge, funded by Pima County, that will carry traffic over the Union Pacific railroad tracks and the Rillito River.

Throughout the project, ADOT is maintaining three lanes of traffic through the work zone during daytime hours and maintaining access to businesses. The public can get project updates and traffic alerts at azdot.gov/i10ina2ruthrauff

Beyond Tucson, ADOT is planning projects to:

• Repair the US 191 bridge over I-10 at milepost 131, about 9 miles west of Willcox. The work will include replacing the girders and deck following a crash that severely damaged the bridge in early 2023. Construction will begin in early 2024 and extend through the summer. For more information, please visit azdot.gov/US191BridgeRepair
• Construct dual roundabouts in Florence. The project includes a dual roundabout at State Route 287 and SR 79B in cooperation with the town of Florence and Maricopa Association of Governments. Nearby, ADOT will construct a single lane roundabout at SR 79B and Florence Heights Drive. The project is scheduled to be complete in summer 2024. For more information, please visit azdot.gov/FlorenceRoundabouts

ADOT also has several pavement improvement projects planned in the coming year, including along 10 miles of I-10 near Casa Grande and 20 miles of SR 90 in and near Sierra Vista. For more information, please visit azdot.gov/projects. 

WILLCOX – The Arizona Department of Transportation has secured federal emergency funds for repairs to a bridge spanning Interstate 10 in southeast Arizona that a large truck severely damaged in a fatal crash earlier this year.

The $5.3 million in funding will enable ADOT to rebuild the superstructure, which includes the girders and deck, of the bridge carrying US 191 over I-10 at milepost 331, about 9 miles west of Willcox. After the crash in early May, ADOT worked with a contractor to build a temporary support structure for the bridge and quickly restore I-10 traffic through the area. 

The US 191 bridge has been closed since the crash in early May, cutting direct access from westbound I-10 to southbound US 191 and from northbound US 191 to westbound I-10. Connections with eastbound I-10 remain open, and alternate routes between westbound I-10 and points south on US 191 include Dragoon Road at milepost 318. ADOT has worked closely with stakeholders who are eager to restore access. 

While the public will first see activity at the project site in early 2024, work has already begun off-site to manufacture key components of the new structure. Once the new girders are delivered to the site, the old US 191 superstructure will be demolished so a new structure can be built in its place.

The project is expected to be complete in summer 2024.

TUCSON – A widening and reconstruction project in the northwest Tucson area has transformed a 4-mile segment of Interstate 10 since work began this spring, demolishing travel lanes, multiple bridges and two interchanges that have been in constant use for decades.

With those familiar features now gone, motorists are starting to see the initial signs of the highway’s new features as the Arizona Department of Transportation rebuilds the roadway to add a fourth travel lane between Ina and Ruthrauff roads.

The $171 million project is now 25 percent complete as crews have regraded sections of the roadway, while also placing foundations for nine new bridges that will span washes and reconstructed interchanges at Orange Grove and Sunset roads.

Within the next several months, even more dramatic changes will become apparent as crews begin pouring the concrete roadway surface and hoisting 121 bridge girders into place.

Many of those girders will make up a reconfigured Sunset Road interchange that will carry the roadway over I-10, reversing the old design that had Sunset beneath the highway. As part of the interchange work, a project funded by Pima County will extend Sunset Road east to River Road, with new bridges over the Union Pacific Railroad tracks and the Rillito River.

ADOT has minimized construction impacts by maintaining three lanes of traffic on the I-10 frontage roads during daytime hours, with lane restrictions limited to overnight hours. However, traffic will return to the newly rebuilt and widened area of I-10 by late 2024. At that time, the reconstructed Orange Grove interchange will also reopen.

The project will continue through late 2025, when the Sunset Road interchange will reopen.

At Orange Grove and Sunset roads, the new interchanges will feature additional lanes on the entrance and exit ramps to promote safety and reduce delays.

While Orange Grove and Sunset road interchanges are closed, motorists should consider Ruthrauff and Ina roads as alternate routes. 

ADOT will maintain access to local businesses throughout the project.

Other project improvements include:

• Rebuilding the Orange Grove Road bridges to allow for higher clearance
• Replacing all nine bridges in the project area, including those over Canada del Oro Wash and Rillito River
• Constructing an access path to the Chuck Huckelberry Loop from Sunset Road
• Related work on lighting, landscaping and drainage

PHOENIX – Heavier traffic is likely on westbound Interstate 10 and Loop 101 (Agua Fria Freeway) in the West Valley on Friday afternoon, Aug. 11, prior to the preseason game between the Arizona Cardinals and Denver Broncos, according to the Arizona Department of Transportation.

Fans heading to State Farm Stadium in Glendale should allow extra time and try to arrive early. Stadium parking lots will open at 3 p.m. Kickoff is scheduled for 7 p.m.

Those traveling from the Chandler/southeast Valley region should consider using westbound/northbound Loop 202 (South Mountain Freeway) to bypass I-10 in the downtown Phoenix area. 

Crews working for Glendale will be prepared to close Loop 101 on- or off-ramps near the stadium at times as part of the city’s plan to enhance traffic flow before and after the game.

Fans also should practice patience after leaving the stadium and be prepared for heavier freeway traffic along sections of Loop 101 and I-10 in the West Valley. 

Real-time highway conditions are available on ADOT’s Arizona Traveler Information site at az511.gov or by calling 511. ADOT also provides information and updates via its Twitter feed, @ArizonaDOT. 

PHOENIX –  The Arizona Department of Transportation is advising motorists to plan ahead and expect to use detours as eastbound Interstate 10 will be closed between SR 51 and US 60 from 10 p.m. Friday, June 16, to 4 a.m. Monday, June 19, for bridge work and a traffic shift. During this closure, the following ramps will be closed. 

• Eastbound I-10 on-ramps at Third, Seventh and Jefferson streets, Buckeye Road, 24th, 32nd and 40th streets and Broadway Road
• The loop ramp from southbound SR 143 to eastbound I-10
• Southbound I-17 on-ramps at Seventh Avenue and Seventh Street
• The ramp from southbound I-17 to eastbound I-10
• The westbound Loop 202 (Red Mountain Freeway) ramp to eastbound I-10
• The southbound SR 51 on-ramp at McDowell Road
• The ramps from southbound SR 51 to eastbound I-10 
• The high-occupancy vehicle (HOV) ramp from eastbound I-10 to eastbound Loop 202 (Red Mountain Freeway)

Detour: Use eastbound Loop 202 (Red Mountain Freeway) to southbound Loop 101 (Price Freeway) to westbound US 60 or Loop 202 (Santan Freeway) to access eastbound I-10 beyond the closure. Drivers traveling on southbound I-17 can use westbound I-10 to eastbound Loop 202 (Red Mountain Freeway).

West Valley drivers heading to the Southeast Valley can bypass the closure by using the Loop 202 (South Mountain Freeway). From I-10 and 59th Avenue, travel south and east to connect with I-10 south of Chandler Boulevard.

Please note: Schedules can quickly change because of weather and other unforeseen situations.

PHOENIX – A busy 8-mile stretch of Interstate 10 in the West Valley has been widened to three lanes in both directions as an Arizona Department of Transportation freeway improvement project moves into the homestretch.

ADOT’s ongoing $82 million project has widened I-10 by one lane in both directions between Verrado Way and State Route 85. The new lanes are designed to improve safety and overall traffic flow for local drivers in Buckeye and motorists on longer trips in or out of the West Valley.

Weeknight and weekend lane restrictions are still planned while crews take care of final work on the project over the next several weeks. Construction on the two-year project started in July 2021.

In addition to the new lanes, I-10: SR 85 to Verrado Way Improvements is constructing new freeway bridges and reconstructing ramps connecting I-10 with SR 85. Crews also modernized the interchanges at Watson and Miller roads by rebuilding them using the diverging diamond design.

The I-10 project in Buckeye is part of the Maricopa Association of Governments’ Regional Transportation Plan. It is funded in part by Prop 400, a dedicated sales tax for transportation improvements approved by Maricopa County voters in 2004.

WILLCOX – Arizona’s interstate freeways are essential corridors for personal and commercial travel. When an incident forces an extended closure, the Arizona Department of Transportation responds quickly to reopen the thoroughfare as soon as possible with safety the No. 1 goal. 

That’s what happened after a fatal semi-tractor trailer crash early Wednesday caused significant damage to the support structure of the US 191 bridge over westbound Interstate 10 just west of Willcox. Less than two days later, an ADOT project reopened the westbound lanes with a temporary support of steel members.

“I am proud of our ADOT team members and dedicated contractors who quickly identified and executed this emergency project,” ADOT Director Jennifer Toth said. “They safely set up detours, got the necessary team in place and worked around the clock to reopen this key corridor in less than two days.” 

Approved by ADOT’s Bridge Group, supervised by engineers in ADOT’s Southeast District and made possible by an emergency procurement, the project engaged Granite Construction Inc. as the prime contractor. Mere hours after the Arizona Department of Public Safety had completed its crash investigation, ADOT and the contractor began working nonstop to demolish the damaged bridge pier and erect the temporary support structure.

What the public can’t see when passing this temporary structure is the intensity of effort, the dedication and the commitment to safety that made it possible. 

A welder who was on site for nearly the entirety of the project told our engineers that he is 80 years old but still at it for his son’s company, which was a subcontractor. “I’ve retired six times but love what I do,” he said. 

Also generously assisting in this monumental effort were state, county and local law enforcement agencies that worked along the detour routes and southeastern Arizona counties and municipalities. The New Mexico Department of Transportation assisted with closing westbound I-10 in New Mexico. 

Now that a temporary structure is in place at the US 191 bridge at I-10 milepost 331, ADOT will determine a long-term plan. At a minimum, the pier, girders and deck where the crash occurred will likely need to be replaced.

There is never a good time for an extended closure, especially one that involves a lengthy detour from such a busy freeway. When it does happen, ADOT team members respond quickly and work as hard as possible with safety as their overriding goal.
