San Francisco International Airport (SFO) has kicked off a new $2.6 billion expansion project for Terminal 3 West (T3 West) as part of its efforts to enhance airport facilities.

This project, which includes a seismic retrofit and substantial renovations, is expected to be completed by fall 2027.

Seismic Retrofit and Enhanced Facilities

The T3 West project goes beyond just expansion; it also involves a seismic retrofit to ensure the terminals strength in case of an earthquake. This 650,000 square foot area of Terminal 3 will undergo a makeover with a new exterior look that will welcome passengers arriving for their flights. Alongside these enhancements there will be new security checkpoints and expanded check in areas that include self-service bag drop zones. A fresh security checkpoint will be positioned on the mezzanine level specifically designed for passengers coming in via the AirTrain.

Connectivity and Passenger Experience Upgrades

To enhance connectivity and passenger experience, the T3 West project will introduce a connector providing travelers direct access to the Customs Hall, in the International Terminal.

The expansion will also include three new gates that can accommodate wide-body planes marking the much needed upgrade, from the current setup which lacks any gates suitable for such aircraft. This improvement is vital for servicing long distance flights and certain domestic routes. These gates will be used by United Airlines and other airlines that operate at SFO.
