Reagan National’s Runway 1/19 will be closed for milling and resurfacing each night, weather-permitting, from 11:00 p.m. to 6:00 a.m. The project — the first such work on the 6,869-foot runway since 1990 — is expected to wrap up before the end of the year.
There are no scheduled departures at DCA after 10:00 p.m., but there are about a dozen regularly-scheduled nighttime arrivals that will need to land on another runway after 11:00 each night, according to airport officials. The runway that’s most likely to be used is Runway 15/33, which points northwest/southeast. Depending on prevailing winds and weather, arriving flights will either be directed to approach from the northwest — thus flying over Rosslyn and the Pentagon — or from the southeast, over Southeast D.C. and the Potomac.
