San Francisco International Airport (SFO) has launched a major project to modernize the western half of Terminal 3, marking a significant step in enhancing the airport’s infrastructure and services. The $2.6 billion Terminal 3 West Modernization project aims to renovate 650,000 square feet of space while adding 200,000 square feet of new facilities, including expanded security checkpoints, more retail and dining options, and improved passenger amenities.
The renovation includes a seismic retrofit to ensure safety during earthquakes and updates to accommodate future passenger growth. San Francisco Mayor London Breed emphasized that the upgrades reflect the city’s commitment to sustainability, innovation, and creating a welcoming experience for visitors and residents alike. The project is expected to bring 500-600 jobs during its peak, with a significant portion of contracts awarded to local businesses.
One of the standout features of this project is the commitment to eco-friendly construction. SFO is aiming for LEED Platinum certification, which means the design incorporates energy-efficient elements such as daylight harvesting, displacement ventilation, photovoltaic cells, and waste heat recovery. In addition, the materials used will be low-carbon, further demonstrating the airport’s commitment to reducing its environmental impact.
A new six-story building will house airline lounges and operational offices, enhancing the airport’s capacity to serve more travelers. The project will add a Federal Inspection Service (FIS) sterile connector for those arriving internationally to provide direct access to the Customs Hall in the International Terminal. This expansion is slated to open in phases, with the western half expected to debut in fall 2027, followed by additional facilities in early 2028 and 2029.
Passengers will continue to have access to the airport during construction via a temporary walkway that will be operational by the 2024 holiday season, ensuring that the renovations do not disrupt travel. With these updates, SFO aims to raise the bar for airport experiences, offering travelers enhanced convenience, safety, and sustainability.
