ASE Airport Modernization Facts: August 2025
Following years of planning and voter approval in November 2024, the Aspen/Pitkin County Airport (ASE) Modernization Program is moving into the design phase.
The project’s centerpiece is a new passenger terminal to better serve travelers, locals and airport staff. Over the next 18 months, a new terminal will be designed to reflect the community-led and values-driven “Common Ground Recommendations” adopted by the Pitkin County Board of County Commissioners (BOCC) in December 2020.

Project Timeline and Milestones

Anticipated over five years, from 2025 to 2029, the phased project schedule is designed to minimize impacts to travelers, residents, and local businesses.
The accelerated schedule is ambitious and will require significant resource commitments to complete the runway reconstruction by the end of 2027. Below is a summary of the project status:
Where We’re Going
- Pursue and secure FAA funding approvals (after Supplemental EA is approved)
- Design new runway and new terminal (mid 2025 – late 2026)
- Hire construction contractors for runway (early 2026) and terminal (mid 2026) projects
- Close airport to reconstruct runway and start terminal construction (April 2027 to Q4 2027)
- Anticipated completion of the new terminal by 2029, at which time the existing terminal will be deconstructed
