Marked County Road Concurrent with US Highway

[Avalanchez71]

How many marked county roads are out there with the county pentagon signed along with the US highways? 

US 85/CR 12 Zahl, ND as an example.

There are some of them in New Jersey, though not always with pentagons.

Can't think of any for California.  There is a couple that multiplex state highways but in general the Letter County Routes are sparsely signed.

Replacing a post I deleted because I misread the title (I'd posted a concurrent state/county highway):

Also in Wisconsin, here is a 3-way (US/State/County) concurrency north of Antigo:  US 45, WI 47, and County J.  Hwy J isn't well marked on 45/47 (if at all, other than at each end), but this is a concurrency for about 3 miles, until J veers east at the north end, and west at the south end.

Not with a pentagon since Olmsted County doesn't use them, but MN/DOT gives Olmsted CSAH 12 equal treatment along its overlap with US 52.

US27 and CR561 used to be duplexed in Minneola, Florida. Now it's "To CR 561". (I think I've seen another in Florida, but can't remember where.)



What is it with CR 551 in New Jersey?





Wisconsin Dells:


I think I've seen a few more in Wisconsin, but can't recall them right now.
