FYI, 1L and 1R are shut down for the next three to four months: SFO will temporarily close two runways during the summer of 2014 to complete the final phase of a multi-year, federally mandated Runway Safety Area (RSA) construction project. Construction is scheduled to begin on May 17, 2014 and is planned to last through September 2014. During the 2014 RSA runway closures, the Airport will operate exclusively on its two major runways, Runways 28L and 28R. During good weather, minor delays may occur during peak periods of traffic demand, such as 9:00 a.m. to 12:00 noon. During bad weather, delays may be similar to those experienced during winter months. The Airport has consulted with airline partners, the FAA and the business community to develop a flight management plan during the construction phase in order to minimize inconvenience to air travelers.
