Silicon Slopes, sorted from the Lehi end.

Two different things sharing one name. It is a nickname for a stretch of the Wasatch Front, credited to Josh James and trademarked in the middle 2000s, with no official boundary, which is why different people use it to mean anything from Ogden to Provo down to the corridor either side of the Point of the Mountain. It is also a nonprofit organisation of the same name, headquartered at 2600 West Executive Parkway in Lehi since 2017, which runs an annual summit. A company being in Silicon Slopes tells you nothing about whether it is in Lehi.

Adobe, whose campus off the interstate opened in December 2012 at about 280,000 square feet on roughly 38 acres. Ancestry, which moved its headquarters here from Provo in 2016. Podium, founded in 2014 and headquartered in Lehi. MX Technologies. And Texas Instruments, which runs a 300 millimetre wafer fab bought from Micron and is building a second beside it. Qualtrics is in Provo and Domo is in American Fork, so neither belongs on a list of Lehi employers even though both appear on them regularly.

No, and this is the corridor's most repeated error. The building carries a genuine architectural feature, a column free bridge section of about 90 feet, but what it crosses is a road inside the Adobe campus. No part of the building spans the interstate. The confusion comes from how the campus reads from a moving car heading north, where the angle makes the bridge look like it is crossing the freeway rather than a service road on the site.

The first one is and the second one is not. Texas Instruments bought the existing 300 millimetre fab from Micron with the sale closing on 22 October 2021 and it opened in December 2022. A second fab, known as LFAB2, broke ground on 2 November 2023 with a published investment figure of about 11 billion dollars and roughly 800 direct roles, and production has been expected in 2026. Summaries in circulation have described the second fab as complete since 2024, which it is not.

Not in Lehi, despite the organisation being based there. The 2026 summit ran from 4 to 7 February in downtown Salt Lake City, in partnership with the city's visitor organisation. The nonprofit itself has been headquartered at 2600 West Executive Parkway in Lehi since 2017. That split between where an organisation sits and where its flagship event happens is worth checking before anybody plans a trip around it.

It is credited to Josh James, who trademarked the phrase in the middle 2000s. The Slopes half of it points at the Wasatch range behind the corridor rather than at anything about the industry. Because it began as a branding exercise rather than as a designation, it has never had an official boundary, and the practical result is that the term stretches or shrinks to fit whoever is using it. For anything that matters, use a city name instead.

It holds the densest part of the corridor the nickname describes, which is why the shorthand often means Lehi even when it is not said. Adobe, Ancestry, Podium, MX and two Texas Instruments wafer fabs sit inside the city, mostly in the band of office and industrial ground alongside the interstate. But the corridor runs well beyond the city in both directions, and the neighbouring towns carry names people frequently misplace into Lehi, so the honest answer is that Lehi is the thickest part of a line rather than the whole of it.

The Silicon Slopes nonprofit's headquarters, opened in 2017. It is the organisation rather than the corridor: a body that runs programmes and events for the state's technology community, including the annual summit, which since 2026 has run in downtown Salt Lake City rather than in Utah County. It is a useful address to know precisely because the name attaches to so many things that have nothing to do with it.

It sets the direction and the hours. A dense band of office and industrial ground runs alongside the interstate through the middle of the city with its own interchanges, so peak flows follow what the buildings do rather than what the residential streets do. Three road projects sit on top of that: the technology corridor widening finished in October 2020, a 2.8 mile freeway to freeway connection at 2100 North runs until the end of 2028, and the Mountain View Corridor gained its first link between the two counties in December 2025.
