Example; US Route 199 touches what was once it's parent US Route 99 (now Oregon Route 99) in Grants Pass. A lot of these highways (mostly US Routes) have come up in recent threads, what other examples are out there?
US 166
US 138 still ends at US 6 (former US 38) in Sterling, CO.
US 180 basically intersects several times with former alignments of US 80, though its eastern terminus is not too far from the current western terminus of US 80 in the Metroplex.
In California, Route 330 (itself former Route 30) intersects what used to be Route 30, now Route 210 near Highland. Route 107 intersects I-405 (former Route 7).

US 166
I have a photo of that exact junction from my August roadtrip!

What about US 310? US 10 still exists, but not in Montana.
I'd have to look up exactly where US 81 went, but US 281 crosses former 81 in San Antonio TX.
US 266's former alignment met US 66, but when I-40 replaced the majority of it, they got separated.
At the US highway level, Indiana does not have any disbanded parent routes, but they do exist on the state highway level.
IN 134 and IN 234 both connect to US 136, which used to be IN 34.

Similarly, IN 143 connects to US421, which used to be IN 43 (a functional route farther south, but locally disbanded). Indiana state routes probably have a few more examples of this. I can't think of any more US Route examples besides US138, the x66's, US310, and the x99's. Do the Washington State Routes starting with 5 count if they no longer connect to I-5?

There are other examples like IN 143 that connect to a disbanded portion of a route that still exists. There are also routes like IN 121 whose parent has been disbanded but doesn't connect to the disbanded route. The two I listed are the only two that connect to an entirely disbanded route.
