Two runways at San Francisco International Airport will alternately be closed next week for federally mandated upgrades, but the construction work is expected to be the last time the airstrips are shuttered during daytime hours.
The upgrades are part of the Runway Safety Areas initiative, which requires U.S. airports to comply with certain safety standards by the end of 2015.
One of the runways, which are undergoing federally-mandated construction, will be closed Tuesday at 12:01 a.m. until 12:59 p.m. Wednesday, SFO officials said. A parallel runway will close Thursday at 12:01 a.m. and reopen Saturday at 8 a.m.
The temporary closure of runways at San Francisco International Airport could lead to flight delays if the weather doesn't play ball, officials said.
“In the event of unfavorable wind conditions during these closures, SFO may experience some delays in aircraft arrivals during peak hours,” airport officials said.
A second set of parallel runways will close next year for construction.
