Noticed another one of these signs on I-77 northbound approaching I-70 that was a bit different in its approach. Instead of showing the time time to various route numbers, it showed the time to the control cities for the 3 directions of the upcoming interchange (Cleveland, Columbus and Wheeling.)
Unrelated note, but I'm probably the only one annoyed by this: Why is Wheeling the primary control of I-70 east from Columbus eastward instead of Pittsburgh? Like I know I-70 doesn't go through Pittsburgh's downtown, but it does enter the metro area, which imo is good enough for a control city if the city is well-known to most travelers. Actually, I don't think Pittsburgh is signed at all on I-70 east; after Wheeling, it's Washington, PA. It is used as a control westbound though.
The reason it is signed westbound--and only on the PA Turnpike--is because of that. Once I-70 leaves the Turnpike, it is Washington, PA, Wheeling, and then Columbus. Wheeling is fine as a control point on I-70 East from Columbus.
Also, I went on Google Maps on checked out what I will call the "variable time signs" there south of Cambridge (just north of the Byesville interchange). The sign has
Canton, Wheeling, and Columbus listed on it. There is also one at the US 22 overpass southbound with Marietta (47 mi/46 min), Wheeling (52 mi/47 min), and Columbus (85 mi/79 min) listed. I have also noticed that the mileage sign on US 22 for the SB I-77 ramp has Marietta 48 and Columbus 84. I tend to believe that the newer sign has the more accurate mileage.
Now returning to
I-71.
