GMP 4 encompasses the construction of a third full commercial runway at TUS, which will substantially improve both operational capacity and airfield safety. Concurrent ASE projects are progressing on both inboard and outboard taxiways, further strengthening airport infrastructure and ensuring compliance with current FAA safety standards. Granite’s Swan Plant, located within five miles of the airport, will supply 77,000 tons of cement treated base and 135,000 tons of concrete aggregates.
“Throughout this ongoing project, Granite has consistently demonstrated a commitment to the Owner's interests, often identifying unnecessary work and offering credits back as a gesture of partnership, something increasingly rare in today’s industry,” said WSP 
This announcement builds on Granite’s earlier work under GMP 3, which included the demolition of the General Aviation runway and foundational civil improvements such as earthwork, storm drain installation, and fencing.
“Granite has been the workhorse of the ASE Program since its inception,” said Granite Area Manager, Zach Thompson. “Our proximity to the airport and longstanding relationship with TAA have positioned us to deliver consistent, high-quality results. GMP 4 is a testament to our team’s commitment to safety, collaboration, and excellence.”
This phase of the project began in August 2025 and is expected to be completed December 2026.
