Title: "Isolated" freeways
Post by: getemngo on June 12, 2014, 07:50:32 PM
In metro Detroit, M-53 has a freeway portion that does not connect to any other freeways - not at its north end, not at its south end, no interchanges. The closest it comes is with M-59, whose freeway section ends a mile west of M-53. M-53's freeway will likely never touch another freeway, unless traffic volumes someday justify extending it north to I-69.

How many other freeways out there have no connections with any other freeways?

Isolated freeway "systems" also count - for example, PA 611 and US 202 around Doylestown, PA have an interchange, but you can't reach any other freeways from the two. Essentially, these are freeways from which you can't access the Interstate Highway System without using surface roads somewhere.

Would NJ90 count, Without crossing the bridge you have only NJ73, a county road, US130 to connect to. NJ 33 has an isolated freeway section that only connects to US9

Many bypass routes.  Also, the US 40 freeway in Baltimore wasn't supposed to be this, but it is.

Perhaps the category should be narrowed to exclude freeways that continue on in expressway/semi-expressway form on one or both ends.  That said:

* The Elgin-O'Hare Expressway in Illinois, although construction is currently underway on the eastward extension that will connect it to I-290.

* The Amstutz Expressway/IL 137 in Waukegan - Originally intended though to connect to I-94 at the IL 137 interchange, although the east-west section along the east-west part of IL 137 didn't survive the EIS process.  The isolated north-south section was supposed to be much longer though.

* IL 8/IL 116 from Washington Street in Peoria to Main Street in East Peoria

As mentioned, there are many such roads along bypasses.  The most interesting to me is the bypass around Seymour, Texas.  It's built as a freeway, although it carries fewer than 3,000 vehicles per day and is in an isolated area that's losing population, which makes it seem like it may have been a bit overdesigned.

I never considered that to be a freeway, although I can see it now.

An isolated system that I'm surprised hasn't been mentioned is I-2, I-69C, and future(?) I-69E in South Texas.

It's not surprising that most of these are bypasses. A fun one will be Georgia's Athens Perimeter once its last traffic light is removed, since it's essentially a beltway example of this!

Would NJ90 count, Without crossing the bridge you have only NJ73, a county road, US130 to connect to.

Why wouldn't you count the bridge? Because it crosses a state line? It's still a freeway that has a full interchange with I-95.

Yeah, there's too many expressway examples to list, and I'd prefer to stay away from those. (I guess my first post breaks this rule, since M-53 has an expressway section at the northern end of its freeway section... but it doesn't break the spirit, since it is a surface highway when it reaches both I-696 and I-69.)

The Humelstown Bypass in PA for US 322.  At both ends it connects to expressway segments of either US 322 or US 422 with also US 322 exiting at its east end for a two lane road.

PA 309 north of Hatfield, PA.  It may be a bypass, but it is actually an isolated freeway as its endpoints are far from the business center along the route it replaces as well as part of a larger network of the PA road system.  PA 309 is a major corridor between Philadelphia and Allentown which is mostly four lanes of both freeway and expressway grade.  This section is isolated from the rest of the state's freeway system as arterial environment exists on both ends.

US 15 near Gettysburg is also more than a bypass of the historic borough as it is quite lengthy and in fact extends a few miles north of where Business US 15 terminates.

If you're talking about freeways that don't connect to the larger freeway/Interstate network, there are a a ton in PA alone (some of which have already been mentioned)

US 6:
Youngsville bypass
Warren bypass

US 11:
Duncannon bypass (with US 15)
Selinsgrove bypass (with US 15)

US 15:
Gettysburg bypass
Duncannon bypass (with US 11)

US 22 :
Armagh bypass
Lewistown to Amity Hall

US 30:
Greensburg bypass
Everett bypass
West York bypass

US 119:
Kittanning bypass (connects to US 422 freeway only)

US 202:
Doylestown bypass

US 219:
Meyersdale bypass
Somerset to north of Ebensburg
Bradford bypass

US 220:
Mill Hall to Jersey Shore

US 222:
Kutztown bypass

US 322:
Milroy to Amity Hall
Hummelstown bypass
Cornwall bypass

US 422:
Prospect bypass
Butler bypass
Kittanning bypass (connects to PA 28 freeway only–which arguably doesn't connect directly to any other freeways)
Indiana bypass

PA 8:
Wesley to Pecan

PA 28:
Etna to Kittanning  (arguably–because it doesn't connect directly to the PA Turnpike)

PA 56:
Johnstown

PA 248:
Bowmanstown to Walnutport

PA 309:
South of Quakertown to Souderton

PA 611:
Doylestown bypess

Not signed as a numbered route:
Harvey Taylor Bypass - Harrisburg

Depending on how you look at it, the entirety of I-99/US 220 (and the connected US 30, US 322, and PA 26 freeways) are also "isolated"  because there isn't a direct connection to the PA Turnpike at the southern end, and the I-99 freeway ends before you reach the I-80 ramps at the northern end.

Post by: Concrete Bob on June 13, 2014, 06:34:08 PM
There are a few of those in Bakersfield.  First there is the Alfred Harrell Highway.  Then there is the Route 178 Crosstown which ends about a mile and a half or so from 99.  There is also the Westside Parkway, as it stands in its current form (of course that will change, so it may not count).

I think Wayne Gretzky Drive in Edmonton, AB would qualify as well. 

Would US 84 north of Santa Fe, NM would qualify?  All of the Alaska freeways?

Map (Google got the coloration correct) (https://www.google.com/maps?q=Hillsboro,+MO&hl=en&ll=38.362118,-90.341263&spn=0.468409,1.056747&sll=38.668356,-90.802002&sspn=7.460832,16.907959&oq=hillsbo&hnear=Hillsboro,+Jefferson+County,+Missouri&t=m&z=11)

Never planned for a tie in to either I-55 or I-270 on the north end, may have been connected to by a freeway to I-55 if the Outer Belt proposals for the MO 109/Rte W/Rte MM/Rte M corridor had been fully realized.

Does having an interchange make it a freeway?  If so, there's a Very Short Section of freeway on US-127 at the M-57 interchange.

And to stretch a point, the I-75 freeway between St. Ignace and Sault Ste. Marie is isolated, as it has a non-freeway bridge at either end.

PA 56 connects to US 219 at the east end

PA 248 - just an interesting note...at the east end, they had to "cantilever" part of the westbound lanes over the eastbound lanes to fit the highway into the gap in the mountain.

It's debatable.  I don't count them for my exit lists, though a couple interchanges in a limited access area makes me think about it.  I do appreciate it when maps mark single interchanges on a limited access section of otherwise non-freeway with the freeway color though.

Va. 7 (Harry Flood Byrd Highway) between Round Hill in the west (near the crest of the Blue Ridge) and Va. 9 near Clarke's Gap and Hamilton qualifies for this list. 

Va. 37 around the west side of Winchester barely qualifies, but IMO it does since it lacks full freeway-to-freeway connections with I-81.

The "new" Warrenton Bypass (parts of U.S. 15, U.S. 17 and U.S. 29) has full freeway access control, but does not connect to any other freeway.

South of Warrenton, the Culpeper Bypass (parts of U.S. 15 and U.S. 29) also qualifies.

Maryland has the Salisbury Bypass (parts of U.S. 50 and U.S. 13) that is full freeway, but has no connection to any other freeway and the (short) Vienna Bypass (part of U.S. 50) and bridge over the Nanticoke River, which also lacks connection to any other freeway. 

One might be able to make the case that Md. 5 where it bypasses Hughesville should be on the list.

Md. 4 (Pennsylvania Avenue Extended and Southern Maryland Boulevard) between Md. 258 (Bristol) in Anne Arundel County and the at-grade signalized intersection at Dower House Road near Andrews AFB in Prince George's County qualifies, though it seems that Maryland SHA is finally going to get rid of the three wreck-prone intersections on Md. 4 between Dower House Road and I-95/I-495.

For Indiana, the Vincennes and Kokomo bypasses should count. And small portions of the Bloomington (from SR 48 to SR 45) and Muncie (from US 35 to SR 32) bypasses should also work.

As for non-bypass isolated freeways, two separate sections of the Lloyd Expressway (west of US 41 and east of US 41, but not including the interchange with US 41.) And even when the Lloyd/41 interchange is rebuilt it will still be isolated unless it is ever connected to I-69 as a full freeway. I guess the SR 49 highway (a bypass but also a through-way as well) from US 30 to Vale Park interchange is another decent stretch of freeway. Finally SR 641, but only temporarily until a connection with I-70 is made.

Perhaps the category should be narrowed to exclude freeways that continue on in expressway/semi-expressway form on one or both ends.  That said:

* The Elgin-O'Hare Expressway in Illinois, although construction is currently underway on the eastward extension that will connect it to I-290.

* The Amstutz Expressway/IL 137 in Waukegan - Originally intended though to connect to I-94 at the IL 137 interchange, although the east-west section along the east-west part of IL 137 didn't survive the EIS process.  The isolated north-south section was supposed to be much longer though.

* IL 8/IL 116 from Washington Street in Peoria to Main Street in East Peoria

You can add to the Illinois list,

* Lawrenceville/Vincennes Bypass (US-50)

* Elgin Bypass (US-20)

* Lake Shore Drive (US-41) north of the Loop

Truman Parkway east from GA 204 to President Street yes, but GA 204 itself is not a freeway at all. There is an interchange at US 17, but the route is at grade on either side of the exit.

Pacific Highway/old US 101 directly connects with I-5, so it's not isolated from the local freeway network at all.

The old I-15/US 395 freeway (Kearny Villa Road) between Miramar Road and Route 163 ALMOST is, but does have a direct ramp from the southbound side to 163 south.

-WI 54 (Mason St Fox River bridge) in Green Bay;
-Campus Dr in Madison;
-US 51 in the Windsor-De Forest area, also in the McFarland area;
-US 14 from just south of the Beltline in Madison to Oregon;
-(until the WI 29 and US 53 freeways were completed in the Eau Claire area in the 2000s, US 53 from the City's north side area to the Rice Lake/Haugen area was an isolated freeway as per the definitions of the O.P. - ditto WI 29 from WI 124 in Chippewa Falls to just east of WI 27 at Cadott);
-US 53 from the north edge of La Crosse through Holmen (its interchange at I-90 includes ramp intersections).
-WI 64 in the Somerset/New Richmond area (note, when the currently under construction Saint Croix River bridge is complete, it will still be isolated - MN 36, which it will feed into, is a suburban surface arterial street);
-WI 26 from NE Janesville to the north end of Milton, from the south end of Fort Atkinson to the north end of Jefferson and around Watertown.

(Note, I am not including several stretches of WI 29, US 10, US 151 NE of Madison, etc, where one and/or the other ends of the major four lane highway directly connect to a system-connected interstate or compatible highway via a true freeway-to-freeway interchange with no intermediate signalized or STOP sign intersections nor roundabouts.  The freeway sections of US 151 west of Madison are thus 'isolated' under this criterium.)

I question some of the earlier California examples listed.  I don't believe that Pacific Highway, Kearney Villa, or La Cienega Blvd are long enough to be considered freeways.  They are merely express portions of local streets (or possibly expressways in the California sense of the term) with no at-grade crossings. 

Also, in California there are Freeway Entrance signs when entering a freeway.  These roads don't have them.  Nor are there end freeways signs at the end.  Even short freeways like the Marina Freeway have these signs.

La Cienega may come close (and in fact was a historical alignment for the never built 170 southern extension) but the light on northbound La Cienega at Stocker kills the freeway treatment.

Simply using "freeway entrance" signs as a strict determiner whether a route is a freeway or not in California is a little bit of a misnomer; by California standards, that would include the one-interchange Skyline Boulevard/Route 35 segment from Hickey Boulevard to Westmoor Avenue in Daly City.  (Conversely, the north part of Junipero Serra Freeway along Route 1 in San Francisco isn't given the freeway entrance signs at all, even though there are three interchanges north of 280!)  The examples brought forth here all have multiple interchanges in a row, which I think is sufficient for purposes of the thread.

1. Pacific Highway wouldn't count anyway as isolated (it's connected to I-5) but it was built as a US 101 freeway alignment in the 1940s.  It DOES have four interchanges before I-5: a Y at Barnett Avenue, Witherby Street, the frontage road, and Washington Street.

2. Kearny Villa was the I-15 (originally US 395) freeway until 1984 and has two interchanges (Miramar Way, Harris Plant Road) before reaching Route 163. 

3. La Cienega, which IS an isolated freeway through Kenneth Hahn State Recreation Area, has actually  four interchanges as well: Wrightcrest Drive (southbound), the recreation area road, Stocker Street (northbound), Slauson Avenue.

You can add Ronald Reagan Parkway (http://www.southeastroads.com/ronald_reagan_parkway.html) east of Atlanta as a bona fide isolated freeway too.

GA 204 is mis-marked on the state highway map as a freeway–or GDOT considers it a freeway between Gateway Blvd and King George Blvd, but hasn't erected any restriction signage to that effect, unlike the US 19/41 Griffin bypass and, apparently, at least some of the US 41 Barnesville bypass (see here (https://www.flickr.com/photos/87345328@N00/9639508493)) and GA 166 south of Carrollton.

There are plans to replace the King George intersection with an interchange, which I suppose would effectively make GA 204 more of a freeway - but it'd no longer be isolated, since it would now connect to Veterans Parkway.

Also in Savannah: the Jimmy Deloach Pkwy extension parallel to Augusta Road is being built as a freeway and will be isolated from I-95 and I-516, at least for now (presumably GDOT's long-term plan is to extend it to I-516, since the extension is designed to allow a southern extension at GA 307).

More isolated ones: Liberty Expressway in Albany GA (part US 19, part US 82); GA 28 (Calhoun Expressway) and GA 104 (Riverwatch Pkwy) in Augusta; and part of Sugarloaf Pkwy near Lawrenceville (although the GA 316 freeway is sneaking eastward at a glacial pace, and eventually should get to the GA 10 Loop in Athens).

Then you have the two oddballs involving the two SEC schools in Mississippi: US 278/MS 6 and MS 7 in Oxford, which only connect to each other at a substandard, and now signalized interchange, and the US 82 freeway between some random point northwest of Starkville and the AL/MS state line, although there are two stubby bits of MS 25 and MS 12 that are de facto freeways that connect at the west end.

You've also got the similarly-weird case of the US 51 freeway between Union City and South Fulton, TN, which only connects to two freeways (the TN stub of the Purchase Pkwy and the TN 22 freeway between Union City and Martin) in substandard ways. And when I-69 is built around Union City, the TN 22 connection will actually become even more circumspect.

In Maryland, US-29 is an isolated freeway for about 3 miles.  It's between:  a very unusual at-grade intersection with Old Columbia Rd. (which not only does not allow cross-street traffic through, but allows exactly one left-turn movement) and a signalized T-intersection with Rivers Edge Rd.  North and south of there, US-29 is a "wishy-washy" freeway, with a mixture of interchanges and at-grades.  I think there's a long-range plan to make it all freeway between White Oak and I-70.

The Osceola Parkway in Kissimmee may be isolated if you consider the small section of highway from just east of FL 535 to just west of Polynesian Islands Boulevard.  The section east of 535 to the toll booth cannot be a freeway because it has u turn pockets and is allowed for future development to have driveways and at grade intersections along the road.

Between FL 535 and Polynesian Islands Boulevard it is a raised structure built on top of an artificial hill with absolutely no access to and from Polynesian Islands Boulevard ( Osceola crosses over Polynesian Isles) and both FL 535 and Poinciana Boulevard have interchanges. 

I would say it counts being at both ends Osceola Parkway is arterial.  That is what makes this a contraversial toll road because of its design unlike other toll roads.

I-587 does have an overpass.  And a ramp to a park-and-ride.

In Ohio:

  • US-127 around Greenville is a "wishy-washy" freeway, alternating between interchanges and at-grade intersections.  At OH-121, there's an oddball hybrid of the two; a grade separation and a single ramp that meets 127 at-grade, covering all movements.
  • Someone else mentioned US-23 through Delaware, OH.  It's also freeway as it passes Marion.  There are also several wishy-washy sections along the way, especially around Upper Sandusky.  Same with US-30 and OH-15; a (arbitrary?) mixture of interchanges and at-grades.

Those are called expressways.  Since expressways often do have chunks a few miles long that meet full freeway standards, such isolated freeways embedded in expressway corridors are supposed to be excluded from this thread.

Between my parent's house and their neighbor's house, the street I grew up on has no cross streets or driveways.  Therefore, this is an isolated super-2 freeway.  :pan:

If it's poorly maintained, going faster than 55 might be unsafe. I have never been there, so I'm not sure.

Given the lack of interchanges, it could be argued that I-587 isn't even a freeway.

Which brings up another good question, Does a freeway necessarily need interchanges, or can it be a section with no grade crossings without interchanges?

I can see both arguments.


I would think it has to have Interchanges, otherwise, it is just a road with no Intersections.  Then again, they gave a freeway designation, and an Interstate number to a glorified ramp in NW Indianapolis.

The portion of Hwy 11 around Monroe itself is in need of resurfacing; the 4-lane portion eastward towards Juda is newer and in much better condition.

Not sure how much it counts as a "isolated" freeway; there's a pedestrian trail crossing (formerly a railroad crossing) at-grade. Granted, for the level of traffic the bypass gets, it's probably adequate.

I remember US 1 in Southern Pines, NC is not connected to the rest of the state's freeway system.  It turns arterial at both of its ends.

The US 30 freeway near Downingtown, PA was isolated before it was extended to connect with US 202.

The US 1 Freeway between the MD State Line and just north of Kennett Square is still isolated from other freeways.

NJ 29 partially counts in my book, between S Warren St and Lee Ave it has a freeway section that is only connected to US1 south, northbound requires the use of either NJ 129, or NJ33.

Oregon says hi. We even have some at 50 and 45 (though the 45 is debatable whether or not it's a freeway).

The betsy ross bridge and approach on the NJ side is 45mph, with 50 once you get past US130.

I-78 is 50mph on the NJ Turnpike Extension.

I-95 through PA is 55mph even in the rural sections outside trenton

Quote from: CrystalWalrein on June 14, 2014, 10:12:56 PMlso, A-70 around Saguenay, Québec, and a short segment of ON 11 north of Thunder Bay.

What's interesting is that, while being only a bypass, A-70 still bears an Autoroute designation... and is a several hours' drive from the closest Autoroute.

Well, what you are saying can be true from one point of view. The closest autoroute is A-20 in Rivière-du-Loup (127 kilometres as a crow flies), but is several hours away as you would have to take an hour-long ferry to go from one to the other

Meanwhile, A-73 is 141 km (ACF) southward, but a mere 1h40 by car ― which is not, IMHO, "several" hours.
------------------

Also, I would point out this 148-kilometre section of NB-8 and NB-11 (two designations, but actually acts as a single continuous road) between Jeanne-Mance Corner and Tide Head in northern Acadie, although I know some purists like their freeways with a median.

The Bend Parkway has always struck me as odd. It was built in the late 20th century/early 21st but yet it was built through the city. I always thought modern freeways were built around cities?

Also, the right turn slip ramp (http://goo.gl/a3kGU4) from Reed Market towards the Parkway..WHY?

Maybe someone mentioned it? The ones that come to mind are the freeway loops/bypasses in Albany, Georgia and Athens, Georgia. Since they're not interstate highways, Georgia decided to keep the sequential number sequence on them when everything was converted in 2000 (just like GA 400 in Fulton and Forsyth Counties).

That one and R-132 through Boucherville (which retains the 100 km/h limit after A-20 exits itself at the city line; granted, it's a canceled autoroute, A-430).

Yeah that's a sketchy ramp. It's marked with a yield sign, and it's hard to see cars coming at you because bushes are in the way, and there's no acceleration lane at all for it after the turn. It doesn't get much traffic though. Probably my biggest gripes with the parkway though are the 45 MPH speed limit, which makes it really dangerous because everyone's going 60 in the left lane and if it's crowded, 40-45 in the right lane, which is really dangerous, as well as the traffic signals on the south end (which they're working to fix, except the one at Powers) and especially the north end (Cooley and Robal). There's long term plans to extend the parkway along the railroad tracks to bypass the shopping center at the north end, but their latest plans have the bypass intersecting current US-97 north of Bend...with another traffic signal! Could they really not find the money for one flyover ramp (it doesn't need to be a full interchange)? It will be many years before this happens, though. Oh, and they should add more/longer accel/decel lanes on the RIROs. Oh, and get rid of the damn at grade crosswalks!

And with the rapid growth of Bend the past 20 years, there's no way our arterials would have been adequate for local traffic if the bypass was built around the east side of town. I wasn't around pre-parkway (well, not in my memory anyways), but my Dad told me horror stories about 3rd St being backup up for a mile at the underpass where it drops to two lanes (total). And Bend has grown even more since the parkway has been built. If it wasn't there now, Bend's traffic would be atrocious, even with an eastern bypass.

And on topic with the thread, you can add the US-97 bypass around Klamath Falls (northern half is super-2, southern half 4 lanes). Not sure if the short Redmond bypass counts (there is only one grade separated interchange).

For those interested in the current proposal for a northern bypass: http://www.us97solutions.org/PDF/East_DS2_Modified_Alternative.pdf

It's not an "isolated freeway" but I find it interesting how the US 69 freeway peters out in Fort Scott, KS.  It goes from a full freeway to a dangerous 4 lane arterial type road with little warning.
