Bush Airport runway work may cause delays for weeks

Runway construction at George Bush Intercontinental Airport was already spilling into schedules Thursday, when the Federal Aviation Administration reported a ground delay tied to the work and average departure delays reached 77 minutes by 9:15 a.m. The delay was expected to last until about 1 p.m. before being lifted later in the day.

Houston Airports temporarily closed Runway 9/27 for a 90-day resurfacing and lighting-improvement project, a major piece of maintenance on a 10,000-foot runway made up of about 1.5 million square feet of concrete. The work includes grinding, retexturing and regrooving the surface, along with the installation of 380 new LED runway lights. Houston Airports said the project is meant to improve runway friction, visibility, drainage and long-term performance while keeping four runways open for operations at Bush Airport.

That matters in Harris County because Bush is not a small local field. The Houston Airport System handled 63.1 million passengers in 2024, and IAH sits about 23 miles north of downtown Houston. In 2025, the airport served 26 passenger airlines and 189 nonstop destinations, a network that makes even a temporary runway closure capable of rippling through business travel, family visits and tight connection windows across Houston and beyond.

The most vulnerable travelers are those flying through Bush during peak departure periods, especially in the afternoon when airport construction has been affecting traffic. Passengers with short layovers, outbound connections on packed domestic banks or international itineraries with little slack are the ones most likely to feel gate holds and late pushes from the terminal. Even when flights do not cancel, delays at a hub with Bush’s scale can quickly cascade from one itinerary to the next.

Houston Airports has urged travelers to arrive early, reserve parking and follow directional signage while construction continues. That advice is especially important for anyone heading to the airport during the weeks ahead, when the runway project will continue alongside other major work, including the Terminal B Transformation Program. At a hub that moves tens of millions of passengers a year, a single runway closure can be enough to turn a normal trip into a longer day.
