Honolulu Closes a Runway Tonight and Keeps Going Until Spring

Daniel K. Inouye International Airport begins intermittent nightly runway closures tonight, 8 September, and the Hawaii Department of Transportation expects them to continue through April 2027. From 8 September to 26 October, Runway 4L-22R closes nightly from 10pm to 8am. Runway 4R-22L then takes its turn from 26 October to 9 November on the same overnight schedule. Runway 8L-26R closes nightly from 8 to 10 September, and is then shortened to 7,000 feet from 10 September until 13 November.

The work covers the Runway 8L Rehabilitation Phase 1 Project and the Taxiway A Reconstruction Project, which together involve realigning runway lights and markings and carrying out environmental sampling. HDOT has said additional closures and restrictions will be announced as they are scheduled, which means the published calendar is a starting point rather than the full picture. Travelers with Hawaii itineraries into the spring should expect the schedule to be revised more than once between now and April.

The 10pm-to-8am window is the awkward part. Honolulu’s overnight hours carry the mainland red-eyes, the transpacific arrivals from Asia and Oceania, and a significant share of the freighter traffic that keeps the islands supplied. Removing a runway from that window does not necessarily cancel flights, but it reduces the airport’s ability to absorb delay: a single late arrival or a weather hold has fewer places to go, and the knock-on effects compound through the early-morning departure bank.

Honolulu has had a difficult stretch on the airfield generally, and HNL is the connecting point for most interisland travel, so disruption there rarely stays contained to one airport. The practical advice for anyone flying to or through Hawaii before spring is unglamorous but effective: avoid the tightest overnight connections, build a buffer on the day you need to be somewhere, and check the HDOT airports notice page before travelling rather than relying on the airline to have flagged a construction restriction in advance.
