The parallel road alongside a freeway

[txstateends]

Yes, we all know of such a thing, although they aren't found everywhere.  The debated regional treatments have been covered here before, I think, but I just found these linkies that stir the pot a bit, and try to give an origin to the term 'feeder road'.  Warning, the podcast in the second link is a bit cringeworthy at times, especially in the musical interludes.

You mean service drives?  Like along the Detroit freeways?

[abefroman329]

I've never seen one outside Atlanta, and I find the fact that they're one-way and it requires such a long detour to go back in the other direction to be a giant pain and far more trouble than it's worth.

In Virginia its half of the previous arterial like the frontage road alongside I-64 near Williamsburg, VA.  It used to be the EB lanes of defunct VA 168 where VDOT made the former WB lanes of the road  into part of today's freeway.  However, at one time that was the sole carriageway of VA 168 as its former WB roadway was added later.

Most states where a freeway took over an existing arterial or expressway has them to access the businesses that were not in the way when the freeway ROW was being transformed.  For example, most of the I-70 Frontage Roads in Missouri were once part of US 40 that is now on the freeway except from Booneville to Columbia where I-70 did get put on its very own path.  Also I-70 east of Wentzville, where US 40 runs with I-64 (also an upgraded arterial to freeway from the original US 40 & 61), that I believe was another old route.  I am not sure its number, but I heard from Alex that it might of been an ALT US 40 designation there.

Missouri calls them Frontage Roads

Seems 'Outer Road' is used more often in eastern Missouri, if not overall in Missouri:

WB Route E near I-55 Exit 111

Route HH near I-55 Exit 69

Imperial Main Street west of I-55 Exit 186

US 50 at I-44 Exit 247

"South Outer 364" in St. Charles County

"North Outer Fourty" near Chesterfield

East Outer Road east of US 61 at Frankford

Outer Road along I-29 at US 136

That may be what the official name is. But I lived in St Louis from 1987 until two months ago and we always referred to them frontage roads unless it has a regular name.

Dunn Road and Pershall Road

[url=https://www.google.com/maps/@38.6260868,-90.4510564,16z?hl=en Des Peres Road, Cedar Valley Road, and Municipal Center Drive

If I heard someone refer to Outer Road, that is what I would assume is the official name. It's a handy reference (and normally preceded by the number before Road). But I think that's a quick way for the state to name the road rather than a generic term for use.

I'll bet you've seen them closer to home, they're just not called anything special in Chicago.

Example on the Ryan: https://goo.gl/maps/S9Adbg7uwQr
Example on the Ike: https://goo.gl/maps/RdmmBfUYK6w

As for Detroit, they're Service Drives (as noted before), and they're pretty consistent throughout the freeway system.

Might be worth noting that the Lodge Service Drive turns into the James Couzens Service Drive at the Wyoming curve but the freeway itself keeps the Lodge name. I know at one time the Lodge turned into the James Couzens at that curve but they never switched the service drive names when they switched the freeway name. And even further, the service drive switches names again after 8 Mile while the freeway keeps the Lodge name before turning into Northwestern Highway after the Mixing Bowl interchange which is the service drive name that it became after 8 Mile.

I’ve never seen one outside Atlanta, and I find the fact that they’re one-way and it requires such a long detour to go back in the other direction to be a giant pain and far more trouble than it’s worth.

Obviously you’ve never been to Texas. Those things are all over the place out there. In fact, they are so ubiquitous out there that they’re commonly called  “Texas style frontage roads”.

They’re called “frontage roads” here in Utah. Never anything else like “service drive”, “access road” or “feeder”. One-way frontage roads with slip ramps are rare in the state, though they do exist on the US 89 freeway in Farmington, and there are plans to install them on several future freeways. However, two-way roads running alongside a freeway are quite common. These are always called “Frontage Road” unless the city has come up with another name for it.

[jakeroot]

"Frontage road" here in WA, and in OR as well. Not always roads with freeway ramps, and some that are two-way.

To be honest, they're quite rare. In WA, the only examples of this type of road are signed with the term "Frontage":

- "South Frontage Road", WA-509 in Tacoma (legit frontage road): https://goo.gl/Yjkz95
- "North Frontage Road", WA-509 in Tacoma (other side of above): https://goo.gl/4AWcMV
- "Frontage Road", in Auburn (two-way, no freeway ramps): https://goo.gl/rQDhro
- "Frontage Road", in Kent (same as above): https://goo.gl/htJp6y

[TheStranger]

The parallel road west of the Eastshore Freeway (I-80/I-580) in Emeryville is simply called "Frontage Road" if I recall:

The Chrysler Service Drive also changes to Stephenson Highway north of I-696.

[D-Dey65]

Hey, in New York they're known as "service roads," even when they're two-way. I tend to call the ones that run in the same direction as the lanes in the main roads as "service roads" and the bi-directional ones as "frontage roads," even in New York.

[jeffandnicole]

In NJ: Frontage Road: https://goo.gl/maps/gHkzb7mRHJ42 

Otherwise, NJ has very few true parallel roads.  One along 295 near Exits 21-22 is termed an Access Road in their documents: https://www.state.nj.us/transportation/refdata/traffic_orders/speed/crownpoint_east.shtm

Right, plus, for example, Bryn Mawr where it runs alongside the Kennedy.

That is mostly correct, I have been to Texas, but only to change planes at DFW and IAH, and did not leave the airport.

I looked it up and saw the same thing you did. I agree, although an argument could be made for splitting Iowa along US 20.

[sparker]

From the '50's to the late '80's, a number of exits on US 99, and later CA 99, in the San Joaquin Valley were simply signed as "Frontage Road", as that was the first surface facility the ramps reached (some of them were barely more than RIRO's).  Starting in the '80's, though, many of these were either removed or re-signed with the names of the closest intersecting road in order to provide improved local navigation.

As with the Midwest in general, there are several different definitions, hence the smiley face.  Some definitions skip Michigan.  Others include Michigan but skip the Dakotas.  Then there's the Weather Service which includes both.

Of course, if you go back to my initial post, I didn't say that all of the Upper Midwest uses Frontage Road.  But you seemed to take it as such.
