Edmonton to Sioux Falls: 1,250 Miles Across the Prairie

The drive from Edmonton, AB to Sioux Falls, SD spans ~1,251 miles (2,013 km) via AB-2 S → I-15 S → I-90 E → I-29 S. Expect 19–20 hours pure driving—two long days or three relaxed ones. You'll cross the Rockies' eastern front, the Montana hi-line, the Badlands, and the Missouri River at Chamberlain.

Border crossing at Sweetgrass/Coutts adds 30–90 minutes. Winter? Check passes (Marias, Lookout) and carry chains. Summer? Thunderstorms roll the plains. Fuel in Shelby, MT or Bismarck, ND—services thin between. A straight shot through big sky country.
