Runway 28L will be closed from 8 p.m. Friday through 8 a.m. Monday to allow construction crews to modify lighting and signs and install infrastructure for new runway status lights, according to airport spokesman Mike McCarron.
The closure will cut the arrival rate in half at the airport, from 60 aircrafts per hour to 30, McCarron said in a statement.
Travelers should expect delays during peak arrival times, especially for flights originating within two hours of SFO.
Travelers expecting to fly in or out of SFO this weekend should contact their airline regarding possible delays.
The runway closure and construction are the first part of a federally mandated runway safety project. The project is expected to be completed by the fall of 2014.
