County roads that are 4 lanes.

[SteveG1988]

Cr541 in Burlington county NJ has 4 lanes with a full cloverleaf, does NJ have any fully expressway quality county routes?

I don't think so, but Nicolls Road (Suffolk CR 97) on Long Island is in certain areas, as is the Central Westchester Parkway (Westchester CR 150).

In Washington State, roads are maintained by the city within which they lie.

WSDOT maintains roads that are State Routes, Interstates, or US highways, and, should any of those run through a city, in conjunction with said city.

All roads that do not meet any of those requirements are maintained by the county. In Pierce County, the largest county-maintained road is (to my knowledge) Canyon Road at 6 lanes (though up to 7 at some locations).

With that said, I'm sure the OP is looking for County Routes, not county-maintained routes. Given that, I have no contributions due to Washington lacking such roads.

OP, would a better question be along the lines of "county routes that are divided highways"? That way, it doesn't have to be a freeway (à la CCR 215 in Las Vegas) but disregards urban city streets.

Bronx River Parkway in Westchester is county maintained, all of which is at least expressway grade, south of Sprain Brook is 6 lanes and limited access.

[Lyon Wonder]

There's Sam Cooper Boulevard in Memphis, most of which is up to interstate standards and was originally supposed to be part of a never-completed inner-city I-40 until the idea was dropped due to opposition and turned over to local control.

[myosh_tino]

There's a ton in Santa Clara County, California.  San Jose and its metro area loves making country road expressways.

Yup, yup, yup! 

CR-G2 --- Lawrence Expwy, 8 lanes (http://goo.gl/maps/lgRPI)
CR-G4 --- San Tomas Expwy, 8 lanes (http://goo.gl/maps/LCCdb)
CR-G21 --- Capitol Expwy, 8 lanes (http://goo.gl/maps/6chfC)

However, not all county routes are expressways.  CR-G10 is Blossom Hill Road located in south San Jose and it is 6 lanes wide.

We even have County routes with short freeway segments in NJ:

We like our County roads.

Begin argument over what constitutes a short freeway segment:

NJ may "love" its county routes, but the residents seem to ignore them. I've lived and/or worked in 5 counties all over the state and have never talked to a person who uses the route numbers, even though they are much better signed now than they used to be. It doesn't help that most county routes have names (unlike many state routes). I'm aware of one that (maybe) has portions that don't have a name, CR 510, though Google labels the sections I'm thinking of "Mendham Road", and locals just call it "old 24" or even just "24". (That part of CR 510 used to be NJ 24 before the NJ 24 freeway was built between I-287 and I-78). Am I wrong? Are there places where these numbers are used?

I've heard of many people who refer to Amwell Rd (CR 514) as simply 514. Same with Georgetown-Franklin Turnpike (CR 518) being referred to as 518. Heck, I even refer to as Mercer County 604 as '601' simply because I use it to get to Somerset County 601 (although I'm fully aware that 604 turns left at Cleveland Lane). At least in central Jersey, the county route numbers are definitely used.

541 also has a Turnpike interchange and widens to 6 lanes at a few points between Sunset Rd (in Burlington Twp) and the Turnpike.  Speaking of which, I wish the NJTA would sign county routes at Turnpike interchanges.

...

Interesting.  In Illinois, roads are maintained by a series of different groups depending on who owns what.

State routes, US highways, and interstates are maintained by IDOT, even within municipalities.  There is an exception below.
Tollways are maintained by ISTHA, but not the Skyway - see below.
County highways are maintained by the county, even within municipalities.
Municipal streets are maintained by the municipality they are in.
If the area is unincorporated, the lesser streets and roads will be maintained by the township.
Some are maintained by a home owners' association, but streets like these are rare.

Now, the major exception: Chicago.

State routes and US highways in Chicago are maintained by the city, including Lake Shore Drive.  All of the expressways are maintained by IDOT (including the Ohio/Ontario Feeder Ramp and the Chinatown Spur).  The Skyway is owned by the city but leased for operation and maintenance.

Nobody knows the 600/700 routes or refers to them by number, with the possible exception of NJ residents who frequent this forum.  I have heard people refer to the 500 series that continue the numbering across county lines, usually in more rural areas.  For example, around my area you will hear references to 530, 539 and 537 quite a bit.

NJDOT has made an effort by posting County routes on signal mast arms for intersections with County routes.  However, they have gotten some of these wrong, at least around the Ocean County area, by inadvertently posting the County 'road' number and not the 'route' number.  Most Ocean County 600 series routes are not posted, and they also have internal 'road' numbers which can change in each municipality on the same route.  I've seen some of these 'road' numbers (sometimes 1 or 2 digits) posted at signals on state highways using the County 'route' shield.  I recall there was an article in the local paper about this issue not too long ago.  The fact that some counties like Monmouth still use 1 and 2 digit 'route' numbers probably contributed to this.

Yes, it is county maintained, but it doesn't have a county route number and does have state parkway route shields.  I for one consider it to be in the gray area in terms of whether or not it counts as a county route.

Per Wikipedia, it carries CR 9987. I'd check that against the state highway inventory.

[Charles2]

Birmingham metro area:

Jefferson CR-99 (Green Springs Hwy.-Columbiana Rd.) connects the south suburbs of Homewood and Vestavia Hills
Shelby CR-17 (Valleydale Rd.): approximately 3 miles of this road are up to 8 lanes wide.

[cpzilliacus]

I believe that all of Maryland's suburban counties have at least some four-lane county-maintained roads (most of the state is not incorporated), and the state only maintains roads with a route number (with some screwball exceptions where a route number is not posted). 

Some examples:

Anne Arundel County:  Riva Road west of Annapolis; Forest Drive west of Annapolis; the west end of College Parkway;
Howard County: Broken Land Parkway; Snowden River Parkway; most of Oakland Mills Road;
Montgomery County: Shady Grove Road on both sides of I-270; Randolph Road and East Randolph Road; Cherry Hill Road;
Prince George's County:  Sheriff Road east of D.C.; Brightseat Road south of Md. 202 (six or more lanes); Cherry Hill Road between Md. 212 and the Montgomery County border;

[D-Dey65]

There are a ton in Florida.  Some of them that come to mind off the top my head are:

Hernando County
CR 570 Wiscon Road

The only part of Wiscon Road that I know of that's two lanes is near the Lowe's and Wal-Mart in Brooksville, and really, those are just turn lanes.

You certainly have four lane segments of County Road in Pasco County like
CR 1; Little Road (which widens to six lanes south of Fivay Drive)
CR 77: Rowan Road and Seven Springs Boulevard.
CR 587; Massachusetts Avenue.
CR 595 Grand Boulevard, in some parts of New Port Richey.
Unmarked CR 611: Mitchell Boulevard.
Unmarked CR 996: Trinity Boulevard, but only to Little Road.

That's all I can think of right now.

Jeff. Co's CR 17 in West Virginia. It heads through a big shopping plaza before it switches to a two-lane through rural country.

[NWI_Irish96]

CR 17 in Elkhart County, IN, is 4 lanes for 19 miles.

[Bitmapped]

Obviously, 4-lane county roads are going to be common in built-up areas.

Looking in more rural areas, here are two examples of divided highways maintained by counties in Ohio:
* In Wayne County east of Wooster, CR 30A encompasses a short stretch of old US 30's divided highway alignment.  US 30 was relocated onto a freeway bypass near 2005.  In Google Street View it's shown as striped as one lane in each direction with an extra wide shoulder for buggies: http://goo.gl/maps/YBiP8

* Near Lordstown, Bailey Road is a county-maintained divided highway to connect GM's Lordstown plant to I-76.  I'm not sure why the I-76 interchange was built here rather than east at SR 45. http://goo.gl/maps/Eq1PY

[CrystalWalrein]

Atlantic-Brigantine Boulevard and Brigantine Avenue (Atlantic CR 638) in Brigantine up to 18th Street South. CR 563 in Northfield. Monmouth CR 55.

[D-Dey65]

I just remembered some others in Hernando County;

CR 574; Spring Hill Drive.
CR 572; Elgin Boulevard, but only between Mariner Boulevard and east of Barclay Avenue (speaking of which...)
CR 587: Mariner Boulevard.
CR 585; Anderson Snow Road north of Industrial Loop and Barclay Avenue south of Elgin Boulevard.
CR 589; Deltona Boulevard between Sewell Street and Northcliffe Boulevard.
CR 493; Sunshine Grove Road from SR 50 to just north of the Star Road/Ken Austin Parkway intersection.

I should've known these since I've used them for the past 15 years.

CR 17 in Elkhart County, IN, is 4 lanes for 19 miles.

I've been wondering for some time now if InDOT intends that to become IN-19 in the near future.  It connects to M-217, and M-205 was decommissioned between US-12 and IN-19.

I don't think the city of Elkhart is willing to take control of the existing IN-19 through town, so I doubt that the Nappanee/Bristol street sections of IN 19 get decomissioned anytime soon, but it does seem logical that CR 17 would become a state highway at some point. 

If the city of Goshen and Elkhart County were willing to take over the northernmost 3 miles of IN 119, then IN 119 could be rerouted onto CR 17 from that intersection up to the state line.  Or CR 17 could just get called IN 215.  The most logical thing to do would be to rename the existing IN 17 to something else which would free up CR 17 to become IN 17, but I don't see that having any chance of actually happening.

Supposedly the intent is still there to improve CR 17 all the way down to US 6, though there are no actual plans in place to do the work.

I believe Bailey Road was selected as the exit due to the proximity of Ohio 45 to the Ohio Turnpike interchange along I-76.  North Jackson (@ 45 & Mahoning Ave - old Ohio 18) is not that large and When 76 (actually 80S at the time) there was even less development.  Access to the GM plant was equally available from 45 and Bailey Road

Would you call Charlotte Route 4 a "county road?"
