As long as they are still signed from the freeway, I'm going to leave them in. I realize the signage on the route is minimal to nonexistent, but for the most part, the routes are pretty obvious. On the other hand, they don't add mileage, as they're all US or GA routes anyway.
Removing I-75 Bus Cordele, as it's not signed from I-75 any more (I couldn't find any signs on GMSV as of July or newer).
Removing I-75 Bus Valdosta (signs appear to have been removed between 2013 and 2019).
Leaving I-75 Bus Tifton (signs still on I-75 as of October 2024, per GMSV), as well as I-95 Bus Darien (unless I see they are removed when I drive through there next week).
Pull request coming soon.
