Regional terminology for frontage roads

[TheHighwayMan3561]

Wisconsin: Frontage Road

They even have a standard sign for it

Same with your northern/western neighbors, except those standard signs are green.

In Michigan they are called service drives.

Unless they have the name of a road that the freeway replaced.  Examples in the Detroit area:
Stephenson Highway (I-75)
11 Mile and 10 Mile Rd (various sections of I-696)
Schoolcraft Rd (I-96)

Those are continuations of local streets. A good example of what you are saying would be the Lodge and James Couzins the freeway keeps the Lodge name while the service drive switches to James couzins. This is because the freeway at that point used to also switch to James Couzins. Most people familiar with the roads around Metro Detroit are going to know those roads by the names they have and most freeways are called by their name rather than their number too.

Exactly as I said - they kept the name of the road that the freeway replaced.  They aren't continuations of local streets, they were the local streets until the freeways came in.

Stephenson, 10 Mile and 11 Mile are all local streets I don't know what you are trying to say but just because they end up as the service drives for 75 and 696 doesn't mean they should stop being called those streets especially when in 10 and 11 Mile's case they pick up on both sides and aren't the service drive anymore.

Going back to the subject, here in the Phoenix area while Frontage Road is the most common and is the official ADOT term, I have heard Access Road from a small number of people.  Elsewhere in the state it seems like Frontage Road is by far the most common.

Since this has been revived, "Service Road" is the most common terminology in New York, but there's not many examples to begin with.

I've seen them posted in Missouri as "Outer Road."

Yes.  In fact, I think this is the only way I've seen them posted in Missouri.  I've also heard people in Missouri refer to them as such.

That's what we call them, yeah, like "South Outer Forty."

There are only a few in West Virginia, and most are officially named "Frontage Road", and they are very seldom marked.  But we usually referred to businesses on them as "on the Main Highway".  A primary example is the McDonalds at the Mineral Wells exit of I-77 near Parkersburg.

That seems to be the most common term on the East Coast from approximately North Carolina northward.  Access Road is more common in Georgia especially the Atlanta area, while Frontage Road is more common in Florida.

Most people just call them frontage road or surface street from what I can tell in California.
