SFO announces weekend closure of runway intersection for maintenance

San Francisco International Airport (SFO) is to close the intersection of two runways to perform maintenance work from 29-30 September at the intersection of Runways 28L and 1R which could lead to flight delays.

Airport crews will perform work on the structure below the pavement in preparation for the holiday traffic and rainy winter weather.

Runway 28L will be closed from Saturday, 29 September at 12:01h until Sunday, 20 September at 07:00h and runway 01R will be closed from Saturday, 29 September from 12:01h – 19.00h.

These runway closures are anticipated to affect normal operations, and the airport said that delays “may be likely during this period”.

Airport director, Ivar C. Satero said: “The intersection of our runways are among the most heavily-used surfaces at SFO.

“This weekend runway maintenance work will ensure this high-traffic area remains available during our busy holiday travel season and through wet weather conditions. I appreciate the patience and understanding of travelers during this closure.”

SFO has a total of four runways, comprised of two pairs of parallel intersecting runways. In 2017, SFO made a series of improvements to Runway 28L, installing new long-lasting LED centerline lights and revising taxiways to improve operational efficiency.
