SFO renovations to affect Terminal 1 access

San Francisco International Airport is closing several areas in and around Terminal 1 starting Friday to facilitate a $2.4 billion renovation project.

The closures, which are expected to last for the next two years, include part of the roadway lane closest to the terminal on both the arrival and departure levels and the connecting walkway between International Boarding Area A and Terminal 1.

Passengers traveling between Terminal 1 and Terminal 2 or the International Terminal are advised to use the AirTrain.

The Southwest Airlines ticket counter will also be relocated to a location closer to those for Frontier and Delta Airlines.

Regular passenger operations are expected to continue in Terminal 1 during the renovation project, which began in June and is expected to take place in phases through 2024.

The project will create an interim Boarding Area B to accommodate passenger activity while a new structure is completed.

The project, which will create a new Terminal 1 Center and Boarding Area B with 24 gates, will also create a new central security checkpoint, consolidated baggage handling system, new dining and retail areas and post-security connecting walkways, according to airport officials.

Terminal 1 opened in 1963 and is the oldest passenger terminal in use at SFO.
