San Francisco International Airport (SFO) announced plans to close Runway 28L for 20 days in September to construct a new base layer below the runway surface. The closure will begin on Saturday, September 7, 2019, and is expected to reopen on Friday, September 27, 2019. Airport officials advise travelers arriving or departing SFO during this period to expect delays and cancellations, as the closure will reduce the Airport’s overall runway capacity.
SFO recommends that travelers opt for early morning flights before 9:00 a.m. PDT during this period, as delays are expected to begin after 9:00 a.m. PDT each day during the closure, and continue for the remainder of the day. Both domestic and international flights may be affected by this activity.
