I can’t verify the exact mileage between exit 261 and exit 250 from the available information, but on I-75 that exit-to-exit span is roughly 11 miles because the exit numbers are about 11 apart.

Quick estimate

  • Exit 261 to exit 250 = about 11 miles.
  • The actual driving distance can vary a little depending on ramp placement and how the exits are numbered in that state.

Note

If you want the most precise road mileage, I’d need the exact state section of I-75, since I-75 runs through multiple states and exit numbering can differ by region.
