MileCheckKansas holds the longest single-state stretch of I-70 in the country — about 424 miles of it — and out there, the mile marker is often the only landmark. Here's how the numbering works, why the Turnpike counts its own miles, and how to see your exact position plus live KDOT conditions in real time.
How Kansas numbers its highways
Kansas mile markers count up from the west and the south. On I-70, mile 0 sits at the Colorado line and the numbers climb all the way to Kansas City. One wrinkle: the Kansas Turnpike — the tolled run carrying I-35 from the Oklahoma line through Wichita, then I-335, I-470, and I-70 up to Kansas City — keeps its own continuous milepost sequence, separate from the free-road numbering on the same interstates. If you're on the Turnpike, report Turnpike miles. Mile marker data for every Kansas highway is bundled into MileCheck and works offline.
The corridors people actually drive
- I-70 crosses about 424 miles from the Colorado line through Hays, Salina, and Topeka to Kansas City — the longest I-70 stretch in any state.
- I-35 and the Kansas Turnpike link Oklahoma, Wichita, Topeka, and Kansas City.
- US-54 and US-50 cross the southern half; US-81 runs the old Meridian Highway north–south through Salina.
- US-83 serves the far west, where towns are forty miles apart and the milepost is the address.
Where mile markers matter most: the long, identical middle
West of Salina, I-70 runs through country where one mile looks a lot like the next hundred. There's no "just past the big curve" out here — location is a milepost, full stop. When you call in a breakdown, a crash, or a cattle truck on its side, the dispatcher's first question is the mile marker, and MileCheck puts the answer on your screen before you dial.
Whiteouts close I-70 every winter
Western Kansas is whiteout country. Wind-driven snow closes I-70 by mile range most winters, sometimes for a day or more, and KDOT gates the on-ramps until the plows win. The closure announcements come as mileposts — "closed from Colby to Salina" is really "closed from one mile range to another." Knowing your own milepost tells you whether you're ahead of the gate or behind it, and which exit town is your best stop before the road shuts.
Live KDOT alerts, in one place
MileCheck pulls live road alerts straight from KDOT: closures, roadwork, and restrictions, tied to the mile marker and direction so you can see what's ahead of you on your route. The alert and your own position sit on the same screen, no state website juggling required.
Everyday and emergency
Whether you're crossing the full 424 in one push, riding the Turnpike between Wichita and Topeka, or stopped on the shoulder somewhere west of Hays, the mile marker is the location Kansas roads run on. MileCheck shows yours in real time, down to a tenth of a mile, even where the cell signal drops — and it works on CarPlay and Android Auto.
