The Left Turn Onto I-19 That Is About to Disappear
ADOT began a $53.4 million rebuild of the I-19 and Irvington Road interchange on July 16, 2026 — new bridge, free-flow ramp, and a spring 2028 finish.
The ramps come apart first and the new movements arrive last. In between there is a nightly width restriction that matters more to your week than any rendering does.
The left turn from eastbound Irvington Road onto northbound Interstate 19 is not going away, but the stopping is. On July 16 the Arizona Department of Transportation began a $53.4 million reconstruction of the I-19 and Irvington interchange that trades that signalized turn for a cloverleaf loop, and the work is scheduled to run about 20 months, into spring 2028. Roughly 85,000 vehicles a day use I-19 at this point, which means the stretch in between will be felt well past the ramps themselves.

What Changes Permanently
The centerpiece is a new Irvington Road bridge over I-19, and the road gets rebuilt around it to match. Westbound Irvington ends up with three through lanes and two dedicated left-turn lanes. Eastbound gets two through lanes plus two more feeding the new cloverleaf ramp, which is the piece that changes how the corner actually behaves: eastbound traffic bound for northbound I-19 will loop onto the freeway instead of waiting at a signal. The freeway on-ramps gain lanes, and a 12-foot-wide path along the south side of the new bridge carries people walking and riding across.
What You Will Feel Between Now and 2028
Work opened with the unglamorous phase: barriers, a temporary pedestrian crossing on the north side of Irvington Road, and restriping to shift traffic off the construction footprint. The number worth writing down is the nightly one. From 9 p.m. to 5 a.m., Irvington Road drops to one lane in each direction with a 12-foot vehicle width restriction — a real constraint if you tow a wide trailer, run a service truck overnight, or have a moving van scheduled. During peak travel, ADOT says two lanes stay open in both directions on I-19 and on Irvington, and access to businesses along the road is maintained throughout the project.
- The Interchange (I-19 at Irvington, New bridge, Free-flow loop): A new Irvington Road bridge over I-19, added lanes on the freeway ramps, and a cloverleaf ramp carrying eastbound Irvington traffic onto northbound I-19 without a stop.
- Tucson Spectrum (1251 W. Irvington Rd., 950,000+ sq ft, 109 acres): The open-air retail center on the interchange's west side runs more than a mile of frontage along I-19, so its access points sit inside the work zone for the duration.
- The Shared Path (12 feet wide, South side, Walking and riding): A 12-foot path on the south side of the finished bridge, replacing the temporary crossing ADOT set up on the north side of Irvington Road when construction began.
Why an Interchange Here Carries More Than Local Traffic
I-19 is short — roughly 63 miles, from the I-10 junction in Tucson to the border at Nogales — and it is the United States leg of the CANAMEX trade corridor, the route freight takes north from the Mariposa Port of Entry. Irvington is one of the last major arterial interchanges before that traffic reaches I-10. It is also the front door to Tucson Spectrum at 1251 W. Irvington Road, an open-air center of more than 950,000 square feet on 109 acres. Between the freight moving through and the retail sitting beside it, a ramp that stops backing up does more work here than the same ramp would somewhere quieter. Nor is this the corridor's first round of surgery: a braided ramp was added at Irvington between 2018 and 2020, during the same stretch that replaced the Ajo Way interchange to the north.
What It Means If You Are Buying Nearby
The ZIP codes flanking the interchange sit toward the accessible end of the metro on price. RealtyTrac put the 85746 median sale price at $286,407 across 580 sales over the past twelve months, and 85714 at $241,685 across 129 sales. Zillow's average home value for Tucson overall was $325,520, down about 2.2 percent over the past year. What a two-year rebuild does to any individual address is not something a median captures — a house whose daily route runs through the closure window lives with this differently than one three minutes the other direction. None of this is investment advice.
Quick reference (July 29, 2026): ADOT began reconstructing the Interstate 19 and Irvington Road interchange in Tucson on July 16, 2026. The $53.4 million project builds a new Irvington Road bridge over I-19, adds a cloverleaf ramp letting eastbound Irvington traffic merge onto northbound I-19 without stopping, widens the freeway ramps, and adds a 12-foot shared path on the bridge's south side. Nightly from 9 p.m. to 5 a.m., Irvington narrows to one lane each way with a 12-foot width restriction. Estimated duration is 20 months, finishing in spring 2028. Schedules and restrictions change — confirm current conditions with ADOT before planning around any single detail.
The Takeaway
If you are shopping near this interchange between now and 2028, the questions that matter are boring and specific: which access point you would actually use, whether it sits inside the work zone, and whether the overnight window collides with how you work. The configuration waiting in spring 2028 — a free-flow loop onto northbound I-19, three westbound through lanes, a path wide enough to ride across — is what the address is worth then. The 20 months in front of it are what you live in first, and that part never shows up in a listing photo.
