San Francisco International Airport (SFO) has launched a $2.6-billion project to modernise its Terminal 3. The modernisation plan involves the revamp of the existing 650,000-sq-ft western half of Terminal 3, including a seismic retrofit, an expanded security checkpoint and new passenger amenities.

The project will also create 200,000 sq ft of additional space, allowing for expanded food, beverage, and retail concessions. The expanded section is expected to open in late 2027. 

“For millions of people around the world, SFO creates their very first impression of the San Francisco Bay Area,” said Mayor London Breed. “We want our residents to be proud of their hometown Airport and for visitors to experience what makes our region great the moment they step off an airplane. This Terminal 3 West Modernization project is another major step that will ensure SFO continues to reflect the innovation, sustainability, and diversity that make San Francisco such an amazing place.”

The Terminal 3 West Modernisation project will create a welcoming new exterior façade greeting travellers curbside, more space for check-in, including state-of-the-art self-bag drop, and new security checkpoints, including one on the mezzanine level for AirTrain passengers.

For arriving international guests, direct access to the Customs Hall located in the International Terminal will be provided via a new Federal Inspection Service (FIS) sterile connector.

The project also includes a new six-storey building which will house both airline lounges and operational office space. The renovated and expanded western half is expected to open in fall 2027, with the six-story building opening in early 2028. A renovated check-in lobby on the eastern end of Terminal 3 is expected to open in early 2029.

During the construction, a temporary walkway will allow passengers to traverse from various terminals and boarding areas around the project site. This temporary walkway, comprising 11 sections currently being fabricated, will be open by the holiday 2024 travel season.

SFO is targeting LEED Platinum certification for this project. Sustainability features will include daylight harvesting, displacement ventilation, on-site photovoltaic cells, waste heat recovery, low carbon steel and concrete, energy smart baggage handling, dynamic glazing, recycled water, hydration stations, health-friendly materials and green building education.

At its peak, the project is anticipated to employ 500-600 workers, and is targeting to award over $173 million in contracts to Local Business Enterprises (LBE).

“We are excited to launch this renovation and expansion project for Terminal 3,” said SFO Airport Director Ivar C Satero. “Our goal is to create an extraordinary airport experience for our guests, leading the way in sustainability and innovation, and we expect this project will once again raise the bar for what travelers can look forward to at SFO.”
