"Isolated" freeways

[Stephane Dumas]

TCH-1 and BC-5 was until they got linked with the South Fraser perimeter highway, a sort of hybrid freeway/expressway with BC-99.

TCH-1 (16th avenue east), is a freeway who stop short from AB-2 and AB-201 in Calgary.

Ring road in Regina and Circle Drive in Saskatoon.

A-70 in Saguenay and A-20 at Rimouski but there a plan to link the orphan gap with the main line.

there some freeway orphan gap of TCH-1 at Corner Brook and St.John's.

The garden state parkway has an isolated section between Exit 0 and exit 9, between 9 and 11 it is an at grade road with cross traffic, thereby isolating the "Freeway" section between the start and exit 9 from the rest of the highway.

Not for much longer, as replacing the at-grade intersections with interchanges is well underway.

True, but until then it counts, right?

I only just remembered this one today...


US-101's bypass of Sequim, WA is up to freeway standards, and is completely isolated.

[lordsutch]

Does GA 204 count near Savanah?  If I am not mistaken it is not a direct freeway to freeway connection between it and I-95 sort of like I-99 to I-80 in PA.

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.

You can add Ronald Reagan Parkway 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) 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.

[Dr Frankenstein]

lso, 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.

I didn't have time to check 'upstream', but would I-587 (NY) be considered 'isolated', as per the criteria of this thread?

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

[Brandon]

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.

If it doesn't have any interchanges, it can only be a freeway if it has at least one overpass/underpass (and even then, not always).

[amroad17]

^ That sounded Alanlandish!

[billtm]

Not sure if this was already mentioned before, but I-22 is isolated... for now.
Also, something that wasn't mentioned was that in Indiana, the Logansport bypass is isolated.

[lepidopteran]

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.

[roadman65]

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.

Whether or not it's connected to I-87 or not depends on whether you think that it goes through the roundabout to the toll plaza.

[lordsutch]

Not sure if this was already mentioned before, but I-22 is isolated... for now.

Only by signage, and the freeway continues west to US 45 which is a freeway (and semi-coincidentally is where the I-22 designation technically ends per FHWA; MDOT just hasn't erected signs yet).

[bugo]

New York I-587 is about as worthless as Wyoming I-180.  Both are as worthless as tits on a boar hog, which is a saying my dad has been saying all my life and HB mentioned that he had heard.

[SteveG1988]

US 301 approaching the summit bridge has a section built to freeway standards, there are no exits along it, but there is an overpass. it starts at a 4 way intersection with DE71 and running to a Four way with Bethel Church Road on the other side of the canal. This freeway was built for later expansion of US301 to a full freeway

[CrystalWalrein]

Actually, AK 1 south of Anchorage and Minnesota Drive have no free-flowing connection to each other. Neither does the Johansen Expressway in Fairbanks....

[Jim]

I'd have more respect for I-587 if its parent did.  I-87 doesn't even acknowledge I-587's existence.

Plus many New Yorkers do not even acknowledge I-87 being its part of the NYS Thruway, people often call it "The Thruway."

Now known as Oak Hill Drive in Pasadena Old 118 and I-210.

Actually it's Oak Grove Drive. I know because I went to La Canada High School, right next to the 210 Freeway.

[lepidopteran]

In Ohio:

• Harshman Ave. in Dayton is a freeway between the RR and the at-grade intersection with Airway Rd.  Actually, it's more of an arterial that had a Jersey barrier placed in the middle.  It has a full interchange with Springfield St.


• 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.


• US-24 around Defiance.  Also around Napoleon; it almost doesn't count because the new "Fort-to-Port" upgrade of 24 to I-475 in Toledo is full freeway (I'm pretty sure), but there's a lone at-grade between this and the Napoleon bypass.


• US-6 becomes a freeway just for its crossing of the Maumee River near Napoleon.  If the missing movement in its interchange with US-24 were included, it, too, would connect to the new Fort-to-Port section and not count.


• 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.

CT 187/189 in Windsor/East Granby.

Ehhhh... I dispute that being a "freeway". It's a section of divided highway that has an interchange. The speed limit is only 50 and it's less than a mile from the 187/189 trumpet to the intersection where they split apart again.

I will grant you, for Connecticut that is special. But in the greater scheme of things if "it's divided and it has an interchange but no driveways or intersections for some length" qualifies something as a freeway, there are a bajillion little segments of ARC roadways, urban overpasses, and random roads wherever that also count.

Here is a similar length segment of road that is divided and has an interchange but no driveways or intersections. Is this a freeway? No, it's an interchange on a divided highway.

It was actually supposed to be part of a freeway that the NIMBYs killed off.  http://www.kurumi.com/roads/ct/woodsriver.html
