As Caldwell Executive begins the anticipated final week of construction on Monday, 21 September, 2026, there will be a few changes to access for certain areas of the airport.

✈️ Caldwell Executive Airport Update: Taxiway Charlie Project ✈️
Please be advised of temporary routing and traffic changes starting Monday, September 21, 2026.

🚧 Gate 5 & Taxiway Charlie: Paving trucks will be exiting through Gate 5. For everyone's safety, a ground flagger will be directing traffic at the A5 and Taxiway Charlie intersection for a 4-to-6-hour window. Please follow all ground instructions.

🚧 Midfield Aviation Access: The temporary asphalt on the east side of Midfield Aviation is being removed. During the final days of this project phase, access to Midfield will be restricted to a single one-way route (in and out) via the north-south taxi lane from Gate 4.

Those users situated to the East of Midfield Aviation may need to access Taxiway Alpha East of A5, taxi West on Alpha to A3. Maneuver south around the General Aviation ramp and back around to the West side of Midfield Aviation with access off the North-South taxi-lane at Gate 4.

Thank you to all our tenants and pilots for your continued patience as we work to improve our airport infrastructure! Please plan accordingly and fly safely.

Attention EUL.

The contracting company is opting not to pave today and will plan on completing the two intersections for Phase 1 on Tuesday, 08 September and mark the taxiway Tuesday evening. Then move into Phase 2 on Wednesday.

Phase 1 area will be closed through September 8 and opened on Wednesday September 9 with Phase 2 also closing on September 9. Current plan is to have Phase 2 complete on October 1.

They are planning to hold their Phase 2 Milling Day next week (Thursday) 10 September 2026.

During the phase 2 closure there will be temporary pavement placed on the east and west side of the Midfield Aviation fuel station to allow users access just south of Charlie during the schedule work period.

Please reach out to the airport office with any questions you may have.
