Every road trip involves the same argument: what's going to be at the next exit? We built Pit Stop to answer that from the passenger seat, which meant mapping every business at every interstate exit in the country. Along the way we ended up with something nobody seems to have published before: an actual census of the American exit ramp.
So we counted. Here is who really runs the interstate.
That's 42% of every exit in the country, more than any restaurant, hotel, or other gas brand. McDonald's is the top food brand at 6,588 exits (33%), with Subway just behind at 6,286.
| Brand | Exits with at least one location | Share of all US exits |
|---|---|---|
| Shell | 8,176 | 42% |
| McDonald's | 6,588 | 33% |
| Subway | 6,286 | 32% |
| Starbucks | 5,014 | 25% |
| Chevron | 3,747 | 19% |
| Holiday Inn brands | 3,575 | 18% |
| Taco Bell | 3,492 | 18% |
| Burger King | 3,474 | 18% |
| Dunkin' | 3,407 | 17% |
| Wendy's | 3,101 | 16% |
The national numbers hide the real story: America's food chains have carved the interstate system into territories, and the borders are sharp.
Dunkin' owns the East Coast. On I-95, the 1,900-mile spine from Maine to Miami, Dunkin' has a location at 50% of all 908 exits. Half the East Coast's exit ramps. No other brand controls any major interstate at that rate.
Starbucks owns the West Coast. On I-5 from the Canadian border to San Diego, Starbucks is the top food brand at 43% of exits, and McDonald's doesn't even make second place (Subway does).
McDonald's owns everything in between. The golden arches are the top food brand on I-75, I-10, I-70, and I-80: the north-south and east-west workhorses of the middle of the country.
| Interstate | Exits | Top food brand | Share of exits |
|---|---|---|---|
| I-95 (Maine–Florida) | 908 | Dunkin' | 50% |
| I-75 (Michigan–Florida) | 598 | McDonald's | 44% |
| I-5 (Washington–California) | 749 | Starbucks | 43% |
| I-10 (California–Florida) | 966 | McDonald's | 34% |
| I-70 (Utah–Maryland) | 704 | McDonald's | 33% |
| I-40 (California–North Carolina) | 832 | Subway | 30% |
| I-80 (California–New Jersey) | 831 | McDonald's | 27% |
| I-90 (Washington–Massachusetts) | 734 | Subway | 27% |
Waffle House has 218 interstate-exit locations in Georgia alone, then 149 in South Carolina, 148 in North Carolina, 113 in Texas, and 110 in Tennessee. Cross into Ohio and Dunkin' outnumbers Waffle House nearly two to one. Florida is the border skirmish: 99 Waffle Houses against 203 Dunkin's. The South's kingdom ends where the drive-thru coffee empire begins.
| State | Waffle House | Dunkin' | Winner |
|---|---|---|---|
| Georgia | 218 | 107 | Waffle House |
| South Carolina | 149 | 56 | Waffle House |
| North Carolina | 148 | 116 | Waffle House |
| Texas | 113 | 91 | Waffle House |
| Tennessee | 110 | 62 | Waffle House |
| Louisiana | 87 | 10 | Waffle House |
| Florida | 99 | 203 | Dunkin' |
| Ohio | 86 | 157 | Dunkin' |
When a chain has a location at half the exits on your route, it stops being a restaurant and becomes infrastructure. It's why road food feels the same for a thousand miles at a time, and it's why finding the independent diner 0.3 miles off the ramp takes a local, or an app that knows every exit. That's the whole reason Pit Stop exists: the chains are easy to find; the good stuff isn't.
