The Local

The New SLC Salt Lake City

Rebuilt from nothing over twelve years, without ever closing

The airport, and the walk to A West.

Four miles from downtown at 4,227 feet, a Delta hub carrying about seventy percent of its traffic, 28,158,007 passengers in 2025, and a 5.1 billion dollar rebuild that has been running since July 2014 with a final phase scheduled for October 2026. Here is what has actually opened, why the walk got famous, and what the 1,175 foot tunnel did about it.

Southern Utah is my home turf. Salt Lake City is not, so these pages are researched rather than lived: checked against city, county and venue sources, and dated so you can see how fresh they are. For the on-the-ground work here I lean on a Salt Lake County partner agent.

Start here


Four miles from downtown, which is the whole argument for it.

Salt Lake City International sits about four miles west of downtown on the old lakebed, at a field elevation of 4,227 feet, and it is frequently described as the closest major airport in the United States to its own city centre. That is roughly ten to fifteen minutes by road outside the peak and about twenty to twenty five minutes on the light rail from the terminal to the middle of town.

It is a Delta hub carrying somewhere around seventy percent of the airport's total traffic, with more than 330 flights leaving daily to a hundred nonstop destinations. In 2025 it handled 28,158,007 passengers, and it is the busiest airport in the Intermountain West by a wide margin. For anybody weighing a move to this valley from a long way away, that connectivity is a genuine and underrated part of the case.

What makes it worth a page rather than a paragraph is that the entire thing was demolished and rebuilt while it kept operating, over twelve years, at a cost of 5.1 billion dollars. It has been billed as the first new hub airport built in the United States in this century, and the final phase was scheduled for October 2026, which means anybody flying through it right now is still walking through a building being finished around them.

They knocked it down without ever closing it.

The reason the layout has felt provisional every time you have flown through since 2020 is that it has been provisional every time you have flown through since 2020. Here is the sequence.

PhaseWhenWhat it delivered
Programme startJuly 2014The decision to replace rather than extend the 1960s terminals
Phase 115 September 2020The new terminal, the first gates, and a completely different arrivals experience
Phase 2October 2023More of Concourse A and the concessions that came with it
Phase 3October 2024The central tunnel between the concourses, on 22 October
Final phaseScheduled October 2026Eleven more gates and six more concessions
At completion94 gates, 101 concessionsA total programme cost of 5.1 billion dollars

Phase dates are as announced by the airport. A programme running twelve years across a live operation has moved before, so confirm the current state at slcairport.com rather than assuming a gate is where it was last time you flew.

The reason for the rebuild rather than a refurbishment was the old terminals themselves. They were built for a different era of aviation and for a different understanding of what the ground under this valley does in an earthquake, and extending them would have been money spent on a building that still had both problems. The decision taken in 2014 was to build a new airport beside the old one and move into it in stages.

What that produced is genuinely good and slightly disorienting. The building is bright, the security hall is enormous and the ceiling heights are the sort of thing you notice. It is also, still, a construction project, and the single most common complaint about it has a specific and now partly solved cause.

The famous walk


A tunnel of 1,175 feet that fixed about half the problem.

When Phase 1 opened in 2020 the two concourses were connected in a way that sent passengers on a long surface level walk between them, and it became the thing everybody said about the new airport within a month of it opening. It was not a design failure so much as an unfinished sequence: the connection that was meant to solve it had not been built yet.

It opened on 22 October 2024. The central tunnel runs 1,175 feet between concourses A and B, it carries moving walkways, and the design provides for two trams to run in it as well. At about eighty million dollars it is an expensive piece of corridor, and it is the reason a connection through here is now a manageable thing rather than a jog.

It has not made the airport small. The far western gates are still a genuine walk from security, the concourses are long by design because that is what a hub needs, and the trams are the part that turns the tunnel from good to properly solved. If you are connecting with a tight window, or travelling with anybody who does not move quickly, treat this as a large airport and give yourself the time you would give one.

The practical version, for a tight connection

Check which concourse both flights use before you land, because a same concourse connection here is short and a cross concourse one is not. Use the moving walkways rather than walking beside them. If you are met by a wheelchair service, request it at booking rather than at the gate, because the distances are exactly the sort that make it worth having. And build in the time you would allow at any hub airport rather than the time you would allow at a regional one, because the passenger numbers say hub even when the mountains outside say otherwise.

The thing people photograph


Two and a half acres of fabric shaped like a canyon.

The airport commissioned a serious art programme as part of the rebuild, and the two pieces most travellers actually notice are both by Gordon Huether. The larger of them is The Canyon, which runs along both walls of the new terminal for 362 feet, about the length of a football pitch. It uses roughly two and a half acres of composite fabric and the equivalent of about seven miles of aluminium tubing, and it is lit so that walking through it reads as walking through slot canyon country.

The second is in the tunnel. The River Tunnel takes the 1,175 foot connection between the concourses and turns it into the rivers and streams of Utah, in blue, which is a sensible thing to do with a corridor that people were previously grumbling their way along. It is the rare case of public art with a direct operational job: it makes a long walk feel shorter.

Both are worth thirty seconds of attention rather than none. In an airport where the mountains are visible from most of the windows, the interesting decision was to bring the landscape inside rather than rely on the view, and it works better than it has any right to.

Getting to it and away from it


A train to the door, and a free lot for whoever is collecting you.

The light rail Green Line runs from downtown to a station at the terminal, which takes about twenty to twenty five minutes and requires no transfer. For a central stay it genuinely replaces a rental car for the airport leg, and it is the single reason a visitor can do a Salt Lake City weekend without driving. Anything beyond the downtown grid still assumes a vehicle.

By road it is about ten to fifteen minutes outside the peak, and the approach is straightforward because the airport is on flat lakebed ground with no hill or bridge in the way. Published parking has started around five dollars an hour with daily rates running roughly ten to fifty five dollars depending on which lot you use, and those numbers move, so take them from the airport's own site rather than from a listing.

The piece worth knowing if somebody is collecting you is the free waiting lot. The Park and Wait Lot sits south of the terminals near economy parking, it costs nothing, and it exists so that a driver does not circle the terminal roadway waiting for a text. Text from the baggage carousel rather than from the aircraft, because the walk from a far gate to the kerb is long enough to matter.

One local quirk: the weather that closes this airport is not usually snow. Salt Lake City is practised at snow, and the field is cleared through storms that would stop airports elsewhere. What causes the delays here is more often the same winter pattern that sits over the valley for days at a time, which brings low visibility with it, and the summer thunderstorm cells that build over the mountains in the late afternoon. If you can choose, a morning departure in July and August avoids the second of those entirely.

Quick answers


The airport, answered.

About four miles west, which is why it is frequently described as the closest major airport in the United States to its own city centre. That works out at roughly ten to fifteen minutes by road outside the peak, or about twenty to twenty five minutes on the TRAX Green Line, which runs from downtown to a station at the terminal with no transfer required. The field sits on the old lakebed at an elevation of 4,227 feet.

The New SLC programme totals 5.1 billion dollars. It began in July 2014, Phase 1 opened on 15 September 2020, Phase 2 in October 2023 and Phase 3 in October 2024, with a final phase of eleven more gates and six more concessions scheduled for October 2026. At completion the airport is designed to carry 94 aircraft gates and 101 concessions, and it has been billed as the first new hub airport built in the United States this century.

Because the connection meant to shorten it had not been built when the terminal opened. Phase 1 in 2020 sent passengers between the two concourses on a long surface level route, and it became the thing everybody said about the new airport within a month. The central tunnel that solves it opened on 22 October 2024. The concourses themselves are still long by design, because that is what a hub needs, so treat this as a large airport when you plan a connection.

A 1,175 foot underground connection between concourses A and B, opened on 22 October 2024 at a cost of about eighty million dollars. It carries moving walkways, and the design provides for two trams to run in it as well. Its artwork is Gordon Huether's The River Tunnel, which renders Utah's rivers and streams in blue along the length of it. It is the reason a cross concourse connection here is now manageable rather than a jog.

Yes, and a dominant one. Delta carries about seventy percent of the airport's total traffic. More than 330 flights depart daily to a hundred nonstop destinations, and the airport handled 28,158,007 passengers in 2025, which makes it the busiest in the Intermountain West by a wide margin. For anybody weighing a move to this valley from a long way away, that connectivity is a genuine and frequently underrated part of the case.

The largest of Gordon Huether's installations for the rebuilt terminal, running along both walls for 362 feet, roughly the length of a football pitch. It uses about two and a half acres of composite fabric and the equivalent of around seven miles of aluminium tubing, lit so that walking through it reads as walking through Utah slot canyon country. In an airport where the mountains are visible from most windows, the interesting decision was to bring the landscape indoors.

The Park and Wait Lot, south of the terminals near economy parking. It costs nothing and it exists so that a driver collecting somebody does not have to circle the terminal roadway. The practical tip is to send the text from the baggage carousel rather than from the aircraft, because the walk from a far gate to the kerb is long enough to matter. Paid parking has started around five dollars an hour with daily rates running roughly ten to fifty five dollars by lot.

Rarely. The city is practised at snow and the field is cleared through storms that would stop airports elsewhere. Delays here more often come from the winter pattern that settles over the valley for days at a time, which brings low visibility with it, and from summer thunderstorm cells that build over the mountains in the late afternoon. If you have a choice in July and August, a morning departure avoids the second of those entirely.

Yes, and the canyon end of that question belongs to the Salt Lake County pages rather than this one, because the resorts are shared by the whole valley rather than owned by this city. What matters at the airport end is that the terminal is four miles from downtown and the canyons are a further drive southeast, so the airport is close to everything by the standards of a ski destination. Start with the Cottonwood canyons page and the canyon winter access page.

Four miles from downtown is worth more than most people price in.

A rebuilt hub airport within fifteen minutes of the city centre changes what a move to this valley actually costs in time, and it is one of the few advantages here that does not depend on which side of the valley you land on. Everything else does. Tell me what you are weighing and I will put you with a Salt Lake County partner agent who works the specific side you are looking at.
