Speed limits on non interstate freeways in your state

[Roadgeekteen]

In Massachusetts, non-interstates can be 65, like MA 24, MA 140, US 44, and MA 146 (I think that's it). But there are still some, like US 3 and MA 3, that are still strangely not 65. I'm also wondering what the highest speed limit on a non interstate freeway is, not counting the Texas tollways.

Pretty sure non-Interstate Freeways, and even Rural Expressways, max out at 65 MPH in IL

There are few non-interstate freeways in Missouri as far as I can tell. Most heavily travelled US highways are expressways or have been overtaken by interstate highways; the last of which I can think of is US 40/61 through St. Louis and St. Charles Counties, which was upgraded to interstate standards and signed as I-64 in the 1990s and early 2000s. The speed limit was 60 for everything but the northernmost 9 miles of the route, where it was 65, and it remains that way today.

Also in the St. Louis area is MO-21. The northern section was originally a two-lane highway and was deemed unsafe, so it was completely rebuilt as a freeway from Fenton to Hillsboro. Speed limit is 60 or 65, I think. Some expressways have speed limits of 65, too, especially if they're signed as US highways.

I thought that Missouri had some expressways at 70?

Yeah I think you're right – I've just never seen one.

I can second this.

Iowa is the same as Illinois - non-interstates only get posted at 65.

I thought that Missouri had some expressways at 70?

Yes:

* MO 13 between I-49 and the far western fringes of Clinton
* US 54 mostly from Mexico to near Jefferson City (with the exception of near I-70, possibly near Fulton as well)
* US 63 between US 54 and Macon (with an exception near Columbia, possibly others)

There may be others, but US 60 between Poplar Bluff and I-55 is certainly not one of them (though IMHO it should be).

I'm surprised that the long US 20 freeway in Iowa is not 70.

I've only been down that stretch from Kingdom City to Fulton; south of there it's probably 70 but it was only 65 when I was there.

Regarding MO and IA...I'm shocked none of the non-Interstate portions of the AotS are signed for 70. Why not the new terrain MO/IA 27 section that includes the Des Moines River Bridge? It is clearly built to higher speed design, even if not fully grade separated

[ilpt4u]

I think Indiana is 60? Any Hoosiers, feel free to correct me

[Revive 755]

^ It's been years since I've been on the stretch, so it would not be impossible that the speed limit was reduced to 65.  At least of 2018 there was a 70 mph stretch north of Kingdom City and as of 2019 it was posted at 70 just south of Kingdom City.

As for the Avenue of the Saints not having any sections posted at 70: I recall reading an article years ago (think it was on the relocation of the NB lanes of MO 13 north of Springfield) that MoDOT did not like posting expressways at 70.  Some of them were posted at 70 to avoid issues with the legislature IIRC.

[Max Rockatansky]

Either 65 or 70 MPH on CA 99.  65 MPH on CA 41, 168, 180, and 198. 

[Great Lakes Roads]

I think Indiana is 60? Any Hoosiers, feel free to correct me

Nope, 65 mph on U.S. 31 around Kokomo and between Plymouth and South Bend, U.S. 24 east of Fort Wayne, U.S. 20/31 bypass in South Bend/Mishawaka/Elkhart area and Indiana State Road 641 in Terre Haute.

Indiana State Road 912 is signed as 55 mph on the existing freeway section in Gary/East Chicago.

[Roadgeekteen]

I think it's 70 on CA 99 and parts of US 101.

[wanderer2575]

In Michigan, a freeway is a freeway.  Interstate or non-interstate route status is irrelevant with regard to determining speed limits.  Portions of the US-10, US-31, US-127, and US-131 freeways have had their speed limits increased to 75 MPH, while portions of the interstates remain at 70 mph or lower.

I stand corrected. I do believe, perhaps incorrectly again, that Rural Divided Expressways are limited to 60 MPH. Thinking like the western end of the Lloyd, much of US 41/IN 63, the Hoosier Heartland Highway, the not-I-69 remaining segments of IN 37, to name a few

[JREwing78]

Wisconsin is inconsistent on this one. It doesn't have a whole lot of non-Interstate freeway mileage to begin with, at least with the transition of US-41 to I-41. US-41/141 between Abrams and I-43 is posted for 70, as is US-14 between Madison and Oregon, US-12 between Elkhorn and the IL line, and US-53 north of Eau Claire.

Other roads with longish freeway stretches (WI Hwy 29, Hwy 26, US-10) are posted for 65 mph; I suspect it's to minimize confusion by not constantly adjusting speed limits when the roads transition from limited-access freeway to controlled-access expressway and back again.

More often, WisDOT will post 65 mph speed limits on roads that are 4-lane divided with controlled access (but with fully limited access for city bypasses).

The only non-interstate freeway in MO that is signed at 70 I can think of is James River Freeway west of Scenic Ave in Springfield.

The Missouri Department of Revenue Driver's Guide states the following:
Rural Freeways (regardless of interstate status)-MAX 70 MPH
Rural Expressways (not to be confused with Freeways)-MAX 65 MPH
Freeways & Expressways in urban areas (I've seen a few urban freeways signed at 55)-MAX 60 MPH
Unless otherwise posted.

The law for Indiana is 60 mph on non-limited-access divided highways, 65 mph on non-interstate freeways, 70 mph on interstate highways.

[sprjus4]

For Virginia, the law currently allows up to 70 mph on any limited access highways.

However, with the exception of the US-29 Lynchburg Bypass that's 70 mph, all non-interstate freeways in the state max out at 65 mph. The majority of the interstate highway system is 70 mph.

[Flint1979]

For Michigan 65 is the highest. On state and US highways in the northern lower peninsula and upper peninsula.

More south in the lower peninsula 55 is the highest you'll see off the interstate. The southern part of the state is more populated than the north by a lot.

Nope. It's 75 on parts of US 127 and other US highway freeways in the Lower peninsula.

Those are freeways that are up to interstate standards.

I said non-interstate freeways.

I think it's 70 on CA 99 and parts of US 101.

Yes, there is a lot of 70 MPH on 99 north of Bakersfield to around the Fresno City Limit.  There is another couple 70 MPH zones between Fresno and Merced.  US 101 has a freeway segment with 70 MPH near San Lucas but much of the highway is an expressway signed 65 MPH.  101 was a little outside of my normal "day-to-day" area to include in my original post.
