While we're at it, does US 25 exist in Ohio? Kentucky maintains the entire bridge into Cincinnati, and their definition of US 25 takes it to the North end of the bridge.
The entire river is in Kentucky, so that definition squares with the logical end.
Huh? The bridge doesn't end right at the riverbank.
http://transportation.ky.gov/Planning/State%20Primary%20Road%20System%20Lists/Kenton.pdf"US 25, from the Boone County Line via Elsmere, Erlanger, Edgewood, Crestview Hills, Lakeside Park, Fort Mitchell, Fort Wright, Park Hills, and Covington and the Clay Wade Bailey Bridge to the end of state maintenance at the end of the bridge structure (0.026 mile north of the Kentucky - Ohio State Line), a distance of 8.998 miles."
Plus this gives the impression that 25 doesn't make it all the way to 3rd St.
That gives me the impression that it does make it there, since you're now junctioning it. But I'm not claiming it ends at 3rd Street, only the north end of the bridge.
There's also KY 17 in Ohio (unfortunately an outdated description): "KY 17, from an intersection with KY 16 at Nicholson, via Madison Pike in Independence, Covington, and Fort Wright, and in Covington: via Madison Avenue, East 20th Street, Greenup Street, the "yoke" approach, and the Roebling Bridge to the end of state maintenance at the north curb line of Pete Rose Way in Cincinnati, Ohio (including the southbound one-way couplet of the "yoke" and Scott Street to the junction with East 20th Street)(also including the roadway over the railroad-owned tunnel near approximate MP 21.3), a distance of 14.805 miles."
