States with speed limits of 70 mph or more in urban areas

I was wondering, which states have roads with speed limits of 70 mph or more in urban areas?

The ones that come to my mind off the top of my head are Colorado, Florida, Kansas, New Mexico, North Dakota, and Texas.

Green Bay freeways except WI 172 have 70 MPH limits, plus WI 54/57 and WI 29 increase speed limits from 65 to 70 as one approaches the city.

Virginia has one segment that might qualify—the I-66 HO/T lanes outside the Beltway have a 70-mph speed limit for their entire length. But that's the only place in Virginia, and it doesn't apply to the entire road (the general-purpose lanes are posted at 55, 60, and 65 mph for various parts of the same stretch of highway). So I wouldn't count Virginia for the list.

Some freeways in Detroit city limits have 70 mph limits. I-75 north of I-94 for example. And in the metro area itself, outside Detroit, most freeways are 70 mph.

I-276 in the Philly suburbs comes to mind posted at 70.

    Illinois has has a couple:
    • I-90/Jane Adams Tollway is 70 in the Rockford area and stays 70 until near O'Hare
    • I-55 and I-74 are 70 around Bloomington-Normal
    • When there was not any construction, I-57 was 70 through Kankakee and the Champaign-Urbana area.
    • I-280 stays at 70 through Rock Island (compared to the 65 mph posted it gets in Iowa, or compared to I-80 in Iowa around the Quad Cities)

The Indiana Toll Road is 70 through at least part of Gary.


In Missouri I-229 is 70 east/south of 6th Street.



In Nebraska US 75/Kennedy Freeway could qualify - it stays 70 until north of Chandler Road



Doesn't I-39/I-90 stay at 70 through Madison, WI?

To the extent that Missoula, Montana is an urban area, I-90 has an 80 mph limit through there.  I couldn't get the hotel in Downtown that I wanted so I had to get the Motel 6 one exit away.  So I had to enter the freeway and accelerate to 80 just to get off at the next exit.  Later I had to do 80 on twisty mountain roads around triple trailers.  80 isn't as fun as I thought it would be.

Also in Wisconsin, the 70 MPH on I-94 starts/ends at Moorland Rd in Brookfield, which is still technically urban. And all of the interstate multiplex in the Madison area is all 70 MPH.

The Florida Turnpike has 70 throughout the Greater Orlando  which has parts urban.   In fact one part was 55 during the 65 max days due to the 65 placement only allowed in sparsely populated areas.
Every day is a winding road, you just got to get used to it.

I-565 gets pretty deep into Huntsville, AL, before the speed limit drops from 70 down to 65 where the viaduct through downtown begins.
It's all fun & games until someone summons Cthulhu and brings about the end of the world.

I also collect traffic lights, road signs, fans, and railroad crossing equipment.

I-15 on at least the south side of the Wasatch Front, including in Provo and even approaching downtown SLC, is 70.

NY doesn't post 70 mph, but if you consider that 65 mph is their equivalent of 70+ mph in other states, there are quite a few examples, including:

  • NY Thruway in Syracuse area
  • NY/I-690 from western terminus to Solvay
  • NY 5/NY 695 in Camillus/Fairmount
  • I-490 from Exit 25 to NY Thruway

Plus a bunch more that are kind of fringe urban, like I-490 west of Exit 6, NY 531, NY 400, and I-190 on Grand Island. And 65 mph could easily be justified on I-290 based on some of these other examples.


roadman65

In New Jersey where, 65 is the 70 there, has 65 mph on I-78 west of Exit 56 in Newark.  That particular stretch of I-78 from the industrial area of Newark to the industrial areas of Hillside/ Union s highly urbanized above the freeway cut.

I think we should be careful with "65 is the 70 there" because states with 70 tend to also post 65 (in fact, a few can be frustratingly stingy with 70, like NH, MD, PA, or both Carolinas).  It does not follow that if NY or NJ were to raise their maximum speed limit that all of those 65 zones would go up to 70.

I agree with that, certainly not all of NY's 65 zones would be raised to 70 mph. In fact one could argue that the Thruway is the only road in the state that truly needs to be higher than 65. Though 70 would also be great on parts of I-81, I-84, I-86, and the Northway, they'd likely end up with 65 zones before and after the 70 zones, so I'd rather they remain 65 than flip-flop in a manner that's hard to keep track of.

Calling 65 the 70 of NY was more a case of that being what we're stuck with since they don't post anything higher, but it is nice that it is used somewhat liberally in suburban/exurban areas.

CA 99 hits 70 MPH north of Shaw Avenue in Fresno.

Very, very little Interstate mileage in Utah is posted at less than 70 MPH. This includes urban mileage. Sub-70 Interstates are basically limited to I-70 over the San Rafael Swell and I-80 between I-15 and Echo. Heck, I have seen 75-80 MPH work zone limits with "work zone" plaques in Utah. Conversely, Utah won't post a non-Interstate higher than 65, so your best rural US Route will never be posted at a higher speed limit than what currently exists in downtown Salt Lake.

California is fun with this. Despite being relatively stingy with 70 MPH limits by western standards, you're unlikely to find a limit below 65 on a divided highway that isn't an urban or suburban arterial, including substandard city center freeways. But I-5 has a few spots with 70 in relatively dense suburban areas north of Tracy, including within the city limits of Lathrop and Woodland.

Idaho, I-84 on the east side of Boise is 80 MPH east of Broadway Avenue, which means that the easternmost Boise exit is in an 80 zone, and 80 MPH extends into city limits.

Nevada, despite being an 80/70 state, will not post above 65 in the urban areas of Reno, Las Vegas, Carson City, or Elko. The only incorporated city in Nevada with a limit of 80 MPH is West Wendover. Lovelock, Winnemucca, Battle Mountain, Carlin, Wells, and Mesquite have 75 MPH within city limits and near the downtown areas, Fernley has 70. Boulder City has 75 within its limits, but this is a technicality as its city limits extend halfway to Searchlight along US 95.

I-49 is 70 MPH throughout the ever-expanding Northwest Arkansas metro.

For Tennessee, the speed limits tend to drop to 55-65 mph as you enter the urban areas around Memphis, Chattanooga, and Knoxville.

However, all of the interstates (8-10 lane urban freeways) feeding into downtown Nashville stay at 70 mph deep into the suburbs. The speed limits don't drop to 65 mph until just a few miles outside the city core.

Knoxville used to be the polar opposite, with 55 mph posted for what seemed like probably a dozen miles in either direction going away from downtown, but they recently raised most of that to 65 mph (and 60 mph on I-40 through downtown).

North Carolina is interesting... the mainline interstates (I-85, I-40, I-73, etc.) drop to 65 mph several miles outside the Raleigh, Greensboro, and Charlotte beltways (I-540/NC-540; I-840/I-73/I-85; I-485), however the beltways themselves are all posted at 70 mph.

The only exception would be I-87 in Raleigh, which is posted at 70 mph all the way to the inner beltway (I-440), and I believe I-40 has a few miles inside the soon-to-be-completed NC-540 interchange at US-70 (future I-42) posted at 70 mph before dropping to 65 mph.

Although it feels like a rural interstate, the northern portion of I-295 between either end of I-64 passes through miles of Richmond suburbs. That highway is posted at 70 mph throughout with the exception of a few miles around I-95.

A bit more questionable, but I-81 maintains its 70 mph speed limits through Bristol and Winchester, which is interesting considering its hard drops to 60 mph near Roanoke and Harrisonburg, and 65 mph zone near Staunton.

Virginia is very generous with 70 mph speed limits in rural areas, with the strange exception of I-77 south of I-81, however you are correct that they shy away from them for the most part near urban areas, generally sticking with 55 mph and 60 mph, and sometimes 65 mph - and is inconsistent at times which of the three gets used.

Define "urban" in this case. The closest I'd say we have is E-470 down in Parker. And that's most certainly suburban.

From what I remember, the high speed limit coming down from the north was further into urbanized area than one would think, too.

Either way, I-15's a good one.
