What's Happening With Tucson Road Construction Right Now?

Southern Arizona is growing, and with that growth comes the inevitable reality of road construction. If you've driven around Tucson recently, you've likely seen the orange cones and heavy equipment on both local streets and major highways. While the detours can add time to a daily commute, these projects are essential for keeping our community connected, reducing long-term congestion, and improving safety for drivers, cyclists, and pedestrians.


Here is a look at the major road projects currently transforming Tucson, what they mean for your daily drive, and how they will benefit the region long into the future.


Highway Improvements Transforming I-10 and I-19

A significant portion of current construction is focused on the interstate corridors that serve as the backbone of Tucson's transportation network.


I-10: Kino to Country Club Project: This is one of the most substantial highway projects currently underway. Scheduled for completion in summer 2028, this project is expanding I-10 to three general-purpose lanes in each direction from east of Park Avenue to Alvernon Way. It includes a completely new traffic interchange at Country Club Road, the reconstruction of the Kino Parkway interchange, and the removal of the Palo Verde Road interchange.


I-19 and Irvington Road Interchange: Kicked off in the summer of 2026, this ADOT project is completely reconstructing the Irvington Road interchange. Irvington Road is being widened to three lanes in each direction, and new lanes are being added to the I-19 on-ramps to significantly improve traffic flow and safety in the area.


I-10 Ruthrauff to Ina Completion: The multi-year project to widen and reconstruct I-10 in the northwest Tucson area reached a major milestone in mid-2026, including the completion of the Sunset Links Road interchange and the highly anticipated Sunset Road extension connecting I-10 to River Road.


Current Construction on Major Arterial Roads

Local commuting is also seeing major investments through the City of Tucson and Pima County.


Valencia Road (Kolb to Houghton): This nearly four-mile stretch is being widened to a six-lane divided roadway. The project, expected to wrap up in the summer of 2026, includes drainage improvements for all-weather access, native landscaping, and enhanced bicycle and ADA-compliant pedestrian facilities.


Houghton Road (22nd Street to Irvington Road): Getting underway in late 2026, this corridor improvement includes critical utility work and new bridges over the Pantano Wash to provide reliable, all-weather access for East Side commuters.


Future Transportation Projects and RTA Next

As current projects wrap up, regional planners are already looking ahead. The original Regional Transportation Authority (RTA) 2006 plan expires in mid-2026. In response, the proposed $2.67 billion "RTA Next" 2026 plan was placed on the March 2026 ballot for Pima County voters.


This massive 20-year blueprint allocates $1.2 billion for multimodal roadway corridors—adding bike lanes, pedestrian facilities, and lane enhancements across 31 projects. It also earmarks over $700 million for transit expansion, including weekend and evening bus service, high-capacity transit development, and neighborhood shuttle connections.


Traffic Impacts and Navigating the Construction

The immediate traffic impacts of these projects are noticeable. Lane restrictions, lowered speed limits, and temporary nighttime closures are common, particularly along the I-10 corridor near Kino and Country Club.


To minimize frustration, it is highly recommended to use navigation apps that track real-time traffic data, allowing you to bypass heavy congestion. When traveling through active work zones, reducing speed and leaving extra space between vehicles is crucial for the safety of both drivers and construction crews.


Long-Term Community Benefits

While construction delays are inconvenient, the long-term benefits to Southern Arizona are profound. These infrastructure investments are designed to address current traffic bottlenecks while accommodating the population growth expected over the next two decades.


Beyond simply moving cars faster, modern road projects prioritize multimodal transportation. By integrating dedicated bike lanes, improved sidewalks, and better public transit access, Tucson is developing a safer and more comprehensive network. Upgraded drainage systems, like those on Valencia Road and the new Pantano Wash bridges, ensure that our monsoon seasons disrupt daily life as little as possible. Ultimately, these improvements support a stronger local economy, enhance our daily quality of life, and ensure Tucson remains an accessible, highly desirable place to live.


Frequently Asked Questions

Where can I find real-time updates on Tucson road closures?

The Arizona Department of Transportation (ADOT) provides real-time highway conditions through the AZ511 website and app. For local city projects, the City of Tucson's Department of Transportation and Mobility website offers project trackers and closure alerts.


When will the I-10 Kino to Country Club project be finished?

The project is currently scheduled for completion in the summer of 2028.


What is the RTA Next plan?

RTA Next is a 20-year, $2.67 billion regional transportation plan designed to fund roadway improvements, safety enhancements, and transit expansion across Pima County from 2026 through 2046.


Why are so many road projects happening at once?

Many of the current projects are the final phases of the original 2006 RTA plan, combined with state-funded ADOT highway improvements. Coordinating these projects helps accommodate Tucson's rapid population growth and addresses aging infrastructure.


How do these projects handle monsoon flooding?

Modern road design in Tucson heavily prioritizes all-weather access. Projects like the Valencia Road widening and the Houghton Road bridges include specialized drainage improvements to prevent the road closures that historically occur during heavy summer rains.
