San Francisco International Airport will close Runway 28L for five months as part of a taxiway improvement project

The project will require the closure of Runway 28 Left to realign two taxiways, “Delta” and “Tango”, which aircraft use to exit from Runways 28 Left and 28 Right. Construction crews will remove existing taxiways and reconstruct Delta and Tango as separate, non-intersecting taxiways. The new configuration will improve safety and bring the layout of the taxiways up to the latest standards, according to SFO.

The five-month closure of Runway 28 Left is scheduled to begin on Tuesday, January 16, and is expected to reopen no later than Monday, July 1, in advance of the Independence Day weekend and peak summer travel season. 

Under normal conditions during this runway closure, SFO will operate all arriving flights on Runway 28 Right. Because the closure will reduce the airport’s overall runway capacity, SFO advises travellers that delays are possible during the closure period. SFO is working with airlines and the FAA to adjust flight schedules to minimise delays. From January to April, SFO anticipates approximately one-third of flights may experience delays from 30-60 minutes, particularly during peak demand periods. Both domestic and international flights may be affected by this activity. Airlines are currently reviewing schedule adjustments for May and June.

The San Francisco International Airport Commission awarded the contract to Golden Gate Constructors to complete this project. The project is federally funded, with an estimated construction cost of $55m.
