What Is Being Built
Turner Construction Company announced the Terminal 3 West Modernization groundbreaking on 5 September 2024. The job is a $2.6 billion design-build contract with Gensler and TEF Design.
The work renovates 650,000 square feet of the western half of Terminal 3 and adds 200,000 square feet. It includes a seismic retrofit, an expanded security checkpoint, a new curbside facade, more check-in space with self-bag drop, and a Federal Inspection Service sterile connector running to the Customs Hall in the International Terminal.
A new six-story building houses airline lounges and operational office space. At peak the airport expects 500 to 600 workers on site, and it targets more than $173 million in contracts to Local Business Enterprises.
The Corridors
Turner built two temporary passenger corridors to route travellers around the work. Its release puts the West Corridor at 1,000 feet and the East Corridor at 400 feet. Both were fabricated as 11 modules at a nearby air cargo yard, then moved across the airfield over 11 consecutive nights.
Turner calls the approach "one and done". The plan moves passengers once across the whole build.
SFO said the walkway, in 11 sections, would open by the holiday 2024 travel season, and it opened on 5 November 2024. SFO's own release measures the two sections at 440 feet, from Gate E2 to the rotunda food court, and 1,000 feet, from the food court to the walkway into the International Terminal G gates. Turner's release gives 400 feet for the second corridor. Measure the route the group will walk.
No published source carries a removal date for the corridors. SFO publishes three opening dates around them: the expanded section in fall 2027, the six-story building in early 2028, and the eastern check-in lobby in early 2029. Put those dates in front of the venue and ask which one ends the corridor.
Where a Coach Stops
SFO lists charter pick-up and drop-off in the courtyards on the Arrivals/Baggage Claim Level. Charter service must be pre-arranged with the operator. The airport's charter page, updated on 28 August 2026, names 20 operators.
Hotel courtesy shuttles use a different kerb. SFO puts the hotel courtesy shuttle zones on the center island of the Departures/Ticketing Level roadway at Harvey Milk Terminal 1, Terminal 2 and Terminal 3, and on the center island of the Arrivals Level roadway at the International Terminal. That page was updated on 1 September 2026 and names 30 hotels.
The coach and the courtesy shuttle use different levels of the same terminal. A run of show that carries one address for both puts them on different floors.
The departures curb carries its own restriction. SFO has closed the Departures Level curbside and the drop-off lane between Doors 6 and 13, and it directs drop-offs to Terminal 2 or to the Terminal 3 arrivals level. Baggage claim carousels 1 to 3 are closed, and the AirTrain station serving Terminal 3 stays shut until the new facility opens in 2027.
The Walk
The record gives corridor lengths and no walking time. Measure the route on a site visit and log it twice: from the coach courtyard to the group check-in desk, and from the shuttle island to the same desk.
The AirTrain removes the roadway from the calculation. Grand Hyatt at SFO sits at the airport entrance, connects to every terminal by AirTrain, and holds 11 meeting rooms and more than 14,000 square feet of event space. A group based there moves from a guest room to the platform and rides to the terminal.
Group check-in counters for international flights sit in the International Terminal. Domestic group check-in goes through the airline. Baggage assistance is available on request at departure, and the airport publishes a passenger services listing for the locations.
Questions for the Venue
Ask which terminal the group uses on arrival and which on departure, and write both into the contract. Ask for the current coach address and the level it sits on. Ask for a walking route from that address to the group's first meeting room, with a timed trial on the day of the site visit.
Ask which construction milestone changes the route, and what notice the venue gives before a change. Ask what the venue charges for a coach that waits. Ask who holds the group's bags between check-out and the coach.
Questions for the Ground Handler
Ask for the permit position on the courtyard. Ask how many minutes the handler builds into the terminal roadway. Ask whether the handler has run a coach group through Terminal 3 since the corridors opened.
Ask for the fallback kerb when the courtyard is occupied. Ask who pays when a coach is turned away. Ask for the driver's staging and rest plan, because a courtyard drop-off and a courtyard pick-up can sit hours apart on the same day.
Terms to Hold to 2029
Attach the airport milestone dates to the contract as a schedule: fall 2027, early 2028, early 2029. Attach a re-walk to each date.
Attach the coach address as an exhibit and date the exhibit. Name the person at the venue who confirms that address in the week before arrival.
Hold the corridor question open in writing. No published source gives a corridor removal date, and a contract signed in 2026 runs into 2027 and 2028.
Where the Record Stops
The Turner release gives no corridor removal date and no walking time. The airport's Terminal 3 construction page lists the closures in force and gives 2027 for the new AirTrain station. The shuttle and charter pages give addresses and no timetable.
