What do you call the small road parallel to the main road?

[Revive 755]

In Missouri, they're signed as "outer roads".

I refer to them as outer roads for this reason.

Same with me.

I voted "other" because "nothing" wasn't an option. We don't generally have those here.

They are officially "Frontage Roads" in Nevada DOT's log of state-maintained highways, and that's the term I have always used.

In Puerto Rico, they are called "Calle Marginal".

Not in Spain, where they are called vía de servicio. Thus, "service road".

In Mexico, they're called or carriles laterales or calles laterales or simply laterales.

In Puerto Rico, they are called "Calle Marginal".

In Cleveland along I-90, they are called "Marginal Roads" too.

They're even mentioned on this exit sign: https://goo.gl/maps/EXHTrmXE1UGGbRqd7

"Frontage Road" for me too.

They call them "feeder roads" in Louisiana, probably pulling from the Houston area. But ever since I moved to North Texas they've been "frontage roads."

Where in Louisiana is this term used? Never heard of "feeder road." Up here along I-20 you will see a mix of terms used. When I was growing up, they were called service roads. But now the LA Dept. Of Total Destruction (LaDOTD) has been putting up signs calling then Frontage roads.

I've always called them frontage roads, but have heard some of the other terms used as well.

I do like the argument for denoting feeder roads as those that are typically one-way and have many ramps with the parallel freeway.

Same here. (Although it's worth pointing out that NDOT's state-maintained highways log has a lot roads classified as "frontage roads" that are not traditional frontage roads as defined in this thread. Most NDOT-maintained roadways not classified as state highway or higher that fall within the bounds of a freeway interchange area are typically classified as a frontage road, including the actual intersecting roadway of an interchange. For example, here's the entire 0.15-mile extent of FR WA55 , which consists of Keystone Avenue within the area of its interchange with I-80–so not a frontage road, but the actual road intersecting. There's countless similar examples. My guess is NDOT didn't want to come up with another roadway classification for these insignificant road segments that are still state-maintained.)

Often, if the frontage road doesn't have another specific road name, NDOT or the local maintaining agency will sign it as "Frontage Road" on street name signs.

Frontage road.

Even in Texas, where they supposedly call them feeder roads, the highway signs say 'Frontage Road'.

No, "FEEDER" is just used south of US-190; primarily in the Houston region.  In North Texas it is either Service Road or Frontage Road.  Frontage road works fine for us because that is what the signs used to say.

Service road (that's what the QEW uses). I'm used to hearing frontage road too though from this forum.

[roadman65]

If Agent Steel were here, if he disliked the OP,  he would say something like. " Just another Road."  

It depends on the people who live around it.

Specifically, Service Road is used in the DFW area, Access Road in San Antonio, and Frontage Road in the rest of Texas.

Back in the summer of 1967, when I was 11, my parents and I traveled across the USA by car from Fort Wayne, IN to visit my mother's brother & family in San Buenaventura, CA (better known as Ventura). The Interstate System as we know it today was only about 1/3 to 1/2 way completed, so we used both freeways and U.S. Highways to cross the country. Roughly, we took US 30 to the Chicago area, then I-80, US 30 & US 6 to western Nebraska, & then I-76/US 6 to Denver, where we visited friends of my parents and spent half a day doing touristy things (such as visiting the Denver Mint). From there, we took the then-tolled Denver-Boulder US 36 route up (literally) to Boulder & Rocky Mountain National Park. After cresting the Continental Divide, we exited the park on US 34 and then picked up US 40 in Granby, CO. Following highway 40 for the next two days, and what was then built of I-80 from east of Salt Lake City on, we eventually spent night five of the trip in Auburn, CA. On day six we entered Sacramento and picked up old US 99 (which was still being converted into CA 99, after the Great CA renumbering of 1964).

Driving south on the 99 through the Big Valley, I noticed a lot of signage for "Frontage Road" throughout that day's journey. My 11 year-old brain thought, "This must be one LONG road!" Of course, as I later learned, these signs were just referring to the freeway's local service/access roads that paralleled the highway. But to me, ALL such paralleling roads will always and forever be FRONTAGE roads, no mater what the FHWA, State and/or local DOTs, and local residents prefer to call them!

How about switching designations on a BGS?  Exit 86 on I-81/I-77 near Fort Chiswell, Virginia was originally marked "Service Road" on the BGS, but nowadays sports the moniker "East Lee Highway" and "Chapman Road" along with shields for SR-F044 and SR-F045.  Needless to say, VDOT uses the "F" on the shields to designate "Frontage Road".

By the way, the exit is actually for "Ready Mix Road" since the two frontage roads are, of course, alongside the Interstate.

Frontage Road is what I would call it. Usually frontage roads are maintained by counties and cities if I am not mistaken?

I don't believe this is true in Texas, but I'm not 100% certain.

It was labeled as I-80S back then..... Until 1975 or so.

In Texas by TxDOT almost universally.
