Greenville-Spartanburg International Airport to Close Runway 4/22 for Two Weekends in September for $27.7M Rehabilitation Project
Why It MattersThe closures illustrate how airports balance federally funded runway rehabilitation with minimal disruption to airline schedules amid projected regional traffic growth.
Greenville-Spartanburg International Airport (GSP) will shut down Runway 4/22 for two full weekends in September, September 11–13 and September 18–20, each a 60-hour closure, as part of Phase 2 of a $27.7 million runway rehabilitation project. The runway was last paved in 2009 and had its shoulders addressed roughly 30 years ago; the work will repair more than 6,500 feet of runway and 11,000 feet of shoulder and safety areas, restore concrete panels and refresh markings.
Phase 1 began July 27 with overnight preliminary work after each day's final scheduled flight to avoid disrupting service, while Phase 3 will bring nightly closures from 11:30 p.m., running September 14 through November 12. During the two weekend closures no passenger or cargo flights will operate and the terminal will be closed to the public, though the project schedule allows Friday flights before 8 p.m. and airlines have arranged to accommodate the shutdowns.
The project is funded mainly through a $25 million federal appropriation grant, with the GSP Airport District covering the remainder from airport operating revenue. GSP recorded more than 3 million passenger trips and 64,593 tons of cargo in 2025, and officials project passenger activity to grow about 5% a year over the next decade.
