Flying J #631 (Lehi)

What they do. Who they serve.

Flying J #631 sits just off I-15 in Lehi, serving the northbound corridor through Utah's Silicon Slopes tech region between Provo and Salt Lake City. Open around the clock, this Pilot Flying J provides 24-hour diesel fueling and ample truck parking for drivers staging loads or breaking up the long haul along the Wasatch Front. The location handles high volumes—over 1,800 reviews reflect steady traffic from regional and long-haul fleets working the I-15 spine. Amenities lean toward fuel and parking rather than full-service repair, making this a solid fuel-and-rest stop for drivers who need a safe place to stage overnight or grab diesel before pushing north into Salt Lake or south toward St. George. The Lehi stop works well for owner-operators and fleet drivers running frequent Utah routes who value reliable access and proven uptime on a critical interstate segment.
