Which state has the highest number of non-Interstate freeways?

[Poiponen13]

Which state has the highest number of non-Interstate freeways? At least I know that California has many, but does it have most? Which other states have also many, and which have fewest? Also, are there any states that do not number exits on such freeways?

[hotdogPi]

I believe it's California simply because it's the largest state by population. Florida also ranks up there, but Florida tends to do all-or-nothing for a given route, while California likes its short freeway segments.

[MATraveler128]

We also have several in Massachusetts. Although I'd argue Texas is probably up there also.

[Poiponen13]

It would be nice that a table showing number of non-Interstate freeways by state would be added to AARoads Wiki.

[Max Rockatansky]

Undoubtedly California.  Almost entire Fresno freeway network consists of state routes (and one relinquished stub of US 99).  The Central Valley has a ton of random freeways which spawn in and out of existence from more conventional highways.  All the big metro areas are strewn with state route freeways.

[wanderer2575]

Michigan (parts and entireties):

M:  5, 6, 8, 10, Connector 13, 14, 39, 47, 53, 59, 60
(I don't count 37 and 66 because their freeway segments are entirely concurrent with Interstates.  The short freeway segments of 25, 55, 85, and 153 are essentially just long ramps.)

US:  10, 23, 31, 127, 131

[SkyPesos]

Ohio (only part of most of these routes are a freeway, and excluding concurrencies with interstates):

US: 20, 22, 23, 24, 30, 33, 35, 50, 52, 62, 422

SR: 2, 4, 7, 8, 10, 11, 16, 32, 79, 82, 104, 126, 129, 161, 315, 562, 711, 823, 844

Substantial freeway (9): 2, 2A, 3, 8, 9, 15, 20, 25, 72

A Tiny Bit O'Freeway (7 or 8): 17, 32, (34 - no longer signed there), 66, 184, 187/189, 190, 349

Unsigned, but more than a long ramp (3): 571, 695, 796

[Dough4872]

I imagine Pennsylvania is up there on this list, have a lot of freeways here that are US and state routes. Also got two freeways that are quadrant routes (Airport Connector and President Biden Expressway).

[formulanone]

Florida has at least 20...

Turnpike (91), Extension (821), 112, 408, 417, 429, 528, 589, 618, 836, 869, 874

Stubby ones: 451, 453, 970, 878

826 has a non-freeway section, but about 20 miles of it is entirely freeway/limited access.

Jacksonville has US 1 Alternate for a few miles. FL 9B is tipped to be Future I-795, but still unposted with an Interstate shield.

Southern Boulevard (FL 80/US 441/98) has a few grade separations in a row, but also some driveway access. Collier County Road 886 is a similar example.

Short sections of 414, 924, and 934 (?) are limited-access for a few exits.

US 1 between Florida City and Key Largo, acts like a Super-2, not quite fitting the bill. 293 is another Super-2 facility, but with no hard divider. Similarly, 538?

Loads of random grade separations that are vaguely a mile long apiece between access points, but I wouldn't count those.

Just a few in Nevada (with some approximate lengths):

US 95 north (west) of I-15 in Las Vegas (23 miles)
US 395 north of I-80 from Reno to the California border (16 miles)
SR 171, the airport connector from I-215 to the entrance to the tunnels under the airport (less than 1 mile)
SR 613, Summerlin Parkway (6 miles)
Clark County Route 215 (37 miles)

The exits on SR 171 and SR 613 are not numbered; the rest of those freeways have numbered exits.

Forgot about 18, I think because it's undivided - but the 18/138 interchange has always been one of my favorites from a design standpoint.

50 and 101 were on the list, forgot about 199. I didn't include 244 since it's functionally a ramp with no additional exits.

I'll go back and add non-state-owned freeways. Could also include Central Expressway in Santa Clara/Sunnyvale, La Cienega Boulevard in Los Angeles.

So...where's the summary of this thread to answer the question?

[Great Lakes Roads]

Indiana-

U.S.: 20, 24, 31 (have exit numbers between Indy and South Bend), 41, 50
SR: 23, 37, 641, 912 (have exit numbers)

[Revive 755]

Also, are there any states that do not number exits on such freeways?

I think numbering exits on non-interstate freeways seems to be the exception in most states.  Iowa is the only state I am aware of that consistently numbers the exits for almost all freeway segments.

As for listing other states:

Illinois

Full Freeway
* IL 6 (has exit numbers)
* IL 255 (has exit numbers)
* IL 390 (has exit numbers)

Freeway segments
* US 20 around Rockford and again around Freeport (no exit numbers)
* US 34 around Galesburg (no exit numbers)
* US 41, multiple segments in Chicagoland (no exit numbers)
* US 50 near the Indiana border (no exit numbers)
* US 51 south of I-72 in the Decatur area (no exit numbers)
* US 67 around Jacksonville (no exit numbers)
* IL 38 (no exit numbers)
* IL 53 (no exit numbers)
* IL 83 (no exit numbers)
* IL 92 in Moline (no exit numbers)
* IL 137/the Amstutz in Waukegan (no exit numbers)
* IL 336 Super-2 segment around Macomb) (no exit numbers)
* IL 394 (no exit numbers)

Missouri

Full Freeways
* MO 364 (has exit numbers)
* MO 370 (has exit numbers)

Freeway Segments
* US 36 with multiple segments (no exit numbers)
* US 50 with segments around Jefferson City and into the KC area (no exit numbers)
* US 54 with multiple segments (no exit numbers)
* US 60 with multiple segments (no exit numbers)
* US 61 with multiple segments (no exit numbers, though I thought there was once an Exit 269 at I-70)
* US 65 with multiple segments (no exit numbers but does have enhanced mile markers on Springfield area and Branson area segments)
* US 63 with multiple segments (no exit numbers)
* US 67 with multiple segments (no exit numbers)
* US 71 segments in the KC area (no exit numbers)
* US 169 in the KC area (no exit numbers)

* MO 76/former MO 465 section (no exit numbers)
* MO 141 with a couple short segments in the St. Louis area (no exit numbers)
* MO 152 in the KC area (no exit numbers)
* MO 179 (short segment around Jefferson City (no exit numbers)
* MO 210 in the KC area (no exit numbers)
* MO 249 in the Joplin area (no exit numbers)
* MO 360 in the Springfield area (no exit numbers)
* MO 367 in the St. Louis area (no exit numbers)
* MO 752 for a very short segment around St. Joseph (no exit numbers)
* Forest Park Parkway through Clayton (no exit numbers)

I don't count the US 63 Rochester bypass since that was a recent rerouting.

But shouldn't US 63 south of US 52 count as freeway? There's certainly some exits there.

[hbelkins]

Prior to the arrival of I-69 and the Kentucky congressional delegation's desire to put interstate numbers on Kentucky's parkways, we had plenty. Then throw in the Owensboro bypass, the southern and western portions of New Circle Road in Lexington, the KY 841 portion of the Jefferson Gene Snyder Freeway, and a few short segments of US 23.

Virginia's map of freeway portions (blue) on roads that are otherwise four-lane surface arterials (red) is interesting. Little short segments of bypasses around certain towns are shown as freeways.

[J N Winkler]

Also, are there any states that do not number exits on such freeways?

I think numbering exits on non-interstate freeways seems to be the exception in most states.  Iowa is the only state I am aware of that consistently numbers the exits for almost all freeway segments.

While the MUTCD has mandated exit numbering on non-Interstate freeways as of the 2009 edition, there has indeed been little progress nationwide toward compliance.

Besides Iowa, California numbers exits on nearly all of its freeways.  SR 33 near Ventura is a rare (possibly unique) exception.



Kansas does not number exits on any non-Interstate freeways.

The following state and US highways have freeway segments:

*  US 24 (north Topeka)

*  US 36 (Hiawatha-Highland)  (Super Two only)

*  US 36 (Missouri River-Wathena)

*  US 50 (Hutchinson)

*  US 54/US 400 (Cunningham bypass)

*  US 54/US 400 (Garden Plain-Kingman)

*  US 54/US 400 (Wichita-Andover) (known locally as Kellogg Avenue)

*  US 54/US 400 (Augusta-Leon)

*  US 59 (Ottawa-Lawrence)

*  US 69 (Shawnee Mission-Fort Scott)

*  US 69 (18th Street Expressway)

*  US 75 (south Topeka)

*  US 75 (north Topeka)

*  US 81 (Salina-Minneapolis)

*  US 169 (Humboldt-Chanute) (Super Two only)

*  US 169/K-7 (Spring Hill-Osawatomie)

*  K-4 (Topeka, known as Oakland Expressway) (Super Two only)

*  K-5 (I-635-Fairfax)

*  K-7 (near Kansas River-Olathe)

*  K-7 (Bonner Springs)

*  K-10 (west Lawrence) (Super Two only)

*  K-10 (Lawrence-Shawnee Mission) (Super Two only west of US 59)

*  K-14/K-96 (Hutchinson-Sterling, the segment near Hutchinson known as the Bob Dole Bypass) (Super Two only)

*  K-18 (I-70-Manhattan)

*  K-61 (Hutchinson; however, the length known locally as "Ken Kennedy Freeway" is not a freeway)

*  K-61 (Inman bypass)

*  K-61 (McPherson south bypass)

*  K-96 (northwest Wichita; State Fair Freeway)

*  K-96 (northeast Wichita; Northeast Freeway)

*  K-254 (Wichita)

This does not include Interstate overlaps or isolated grade separations, of which there are many in Kansas.  No state or US route is developed to freeway standard throughout its entire length.

All of the Interstates other than the Turnpike have prohibition signs that are functionally equivalent to the start-of-motorway ("chopsticks") signs used in European countries.  Among the non-Interstate freeways, only K-10 (Lawrence-Shawnee Mission) and US 81 (Salina-Minneapolis) have them.  The Turnpike uses just a tiny "Pedestrians Prohibited" sign.

Here is a non-exhaustive list for Colorado:

• US 6, 6th Avenue Freeway (10 miles)
• US 24 in Colorado Springs (2 miles)
• US 36, Denver-Boulder Turnpike (20 miles)
• US 285 in Denver (11 miles)
• CO 21, Powers Boulevard (6 miles)
• CO 47, César Chávez Memorial Highway (3 miles)
• CO 58, Golden Freeway (5 miles)
• CO 115 at Fort Carson (3 miles)
• CO 470 (27 miles)
• E-470 (47 miles)
• Northwest Parkway (8 miles)
• Peña Boulevard (11 miles)
• South Academy Boulevard I-25 to MEP Pkwy (2 miles)

Of course, short limited-access segments and glorified ramps were not included.

The only freeways on this list with exit numbers are the 470 loop, CO 21, and the spurs into Golden and DIA. Powers Boulevard is strange because its exit numbers run parallel to I-25's. The plan might be to reroute I-25 around the city.
