The $400M Runway Rebuild South of Town

The largest and most expensive safety project in the airport's history, and the new commercial-length runway is due in 2027.

Most Tucson infrastructure projects you can watch from the road. This one you mostly see from a window seat. Tucson International Airport is in the middle of the largest, most expensive safety project in its history — the Airfield Safety Enhancement (ASE) Program, a $400-million-plus rebuild of the airfield itself that is tearing out and relocating runways and taxiways to meet current Federal Aviation Administration safety standards. It started in 2022, it will run the better part of a decade, and its centerpiece — a brand-new commercial-length runway on the south side of the field — is now planned for completion in 2027, pending additional FAA funding.

Why Rebuild a Working Airport?

Tucson International's layout dates to the middle of the last century, and FAA safety standards have moved on — today they call for more separation between parallel runways and cleaner overall airfield geometry than the old field was built to. The ASE Program is the fix. It demolishes and relocates the airport's smaller inner runway, a general-aviation strip 8,400 feet long and 75 feet wide, and replaces it with a new parallel runway measuring 11,000 feet by 150 feet — long and strong enough to carry commercial, military, and general-aviation aircraft on the same surface — along with a new center taxiway and a modernized layout. The Tucson Airport Authority calls it the most critical safety project in its history. The whole program is budgeted north of $400 million in 2023 dollars, paid for through a mix of FAA grants and airport revenue, and is expected to take 8 to 10 years of construction.

What's Been Built, and What's Next

The work has arrived in stages. The first piece — an end-around taxiway at the west end of the field — reached substantial completion in December 2022: roughly 40,000 tons of asphalt at a cost of about $25.7 million, letting aircraft cross from one side of the field to the other without taxiing across an active runway. Then on November 30, 2023, the airport permanently closed its old inner runway, 11R/29L, and began building the new south parallel runway and center taxiway, now planned for completion in 2027, pending additional FAA funding. The program is being delivered by Granite Construction under a construction-manager-at-risk contract, with WSP as program and construction manager and Jacobs and Dibble handling design. In November 2025, Granite launched 'GMP 4' — a roughly $70 million work package, the fourth guaranteed-maximum-price phase in the sequence.

• End-Around Taxiway — Done (2022) (West end of field, ~$25.7M, Completed Dec 2022): The first stage, an end-around taxiway built with roughly 40,000 tons of asphalt, lets planes get from one side of the airfield to the other without crossing an active runway. It reached substantial completion in December 2022.
• New South Runway — Underway (11,000 ft x 150 ft, Started late 2023, Planned for 2027): The centerpiece. Old runway 11R/29L closed for good on November 30, 2023, and crews began building the new commercial-length south parallel runway and center taxiway in its place, now planned for completion in 2027, pending additional FAA funding.
• GMP 4 Package — Underway (~$70M package, Launched Nov 2025, Granite CMAR): The fourth guaranteed-maximum-price work package under Granite's construction-manager-at-risk contract, worth about $70 million, launched in November 2025 to keep the airfield rebuild moving through its middle innings.
• Full Program — Through the 2030s ($400M+, 8–10 years, FAA compliance): Taken together, the phases redraw the entire airfield to current FAA safety standards over an estimated 8 to 10 years of construction, funded through FAA grants and airport revenue.

The New Runway Map

If you fly out of Tucson, some of the numbers on the charts have already changed. As part of the rebuild the airport renumbered its runways: the main runway 11L/29R became 12/30, and the crosswind runway 3/21 became 4/22. When the new south runway opens it will be designated 12R/30L, and today's 12/30 will become 12L/30R. Pilots and controllers care about this more than passengers do, but it's the visible sign that the field's geometry is being genuinely redrawn — not just repaved.

Why It Matters Off the Tarmac

TUS sits on Tucson's south side and is one of the region's biggest economic engines. Per the Tucson Airport Authority's 2024 economic-impact study, its two airports — TUS and the reliever Ryan Airfield — together support a roughly $10.9 billion annual impact across Southern Arizona and more than 42,000 jobs, and TUS moved more than 3.8 million passengers in 2024 — up about 3.9% — coming in just under 4 million (about 3.9 million) in 2025 rather than crossing that mark. The field is also home to the Arizona Air National Guard, which flies from it and is one reason the new runway has to carry military aircraft as well as airliners. For anyone buying or selling nearby, the airport is both a jobs anchor and a permanent neighbor: in the 85706 ZIP code around it, the median sale price was roughly $263,000 over the trailing year on 477 sales per Realtytrac — well below the broader metro — against a typical Tucson home value near $326,000 (Zillow) and a metro median around $320,000 (Redfin) in mid-2026. A bigger, safer, busier airport reinforces the south-side and southeast-side job base a lot of that housing depends on.

Quick reference (July 7, 2026): Tucson International Airport's Airfield Safety Enhancement (ASE) Program is a $400-million-plus, 8-to-10-year rebuild of the airfield to meet current FAA safety standards, funded by FAA grants and airport revenue. It replaces the old 8,400-by-75-foot inner runway with a new 11,000-by-150-foot south parallel runway plus a center taxiway. The end-around taxiway finished in December 2022 (~$25.7M); old runway 11R/29L closed November 30, 2023 and the new south runway is now planned for completion in 2027 (pending additional FAA funding); Granite Construction is delivering it under a construction-manager-at-risk contract (WSP program manager; Jacobs and Dibble design), with the ~$70M GMP 4 package launched November 2025. The new runway will be designated 12R/30L. Schedules on projects this size move — confirm current status with the Tucson Airport Authority before relying on any single date.

The Ground Under the Planes

It's easy to fly in and out of Tucson and never notice that the ground under the planes is being rebuilt from scratch. But the ASE Program is one of the largest public-infrastructure efforts in the metro right now — a decade-long, $400-million-plus reworking of the field that ends with a longer, safer commercial runway on the south side. The near-term milestone is the new south runway, now planned for completion in 2027 pending additional FAA funding; the longer story is a modernized airport with more capacity anchoring the south-side economy. For residents, commuters, and anyone weighing a move to the south or southeast side, it's worth knowing what's taking shape past the end of the runway lights.
