Freeways that meet without an interchange

[Bigmikelakers]

Just browsing through Google Maps tonight and noticed something strange. In San Jose the 880 and CA 87 dont have an interchange. Are they any other instances of freeways meeting without an interchange? Has to be very rare.

[wytout]

In CT, CT 40 (the Mount Carmel Connector) and Route 15 (Wilbur Cross Parkway).  Both roads are controlled access, divided expressways.
Route 40 is carried over the wilbur cross w/ no interchange.

I know we're gone through this before but I didn't find it in a quick search on "Freeways no connect"

This is not a rare condition in PA thanks to the PTC.  Many across the state don't have interchanges.

Current:
PA 28
US 119
US 219
US 220/I-99
I-70 (Breezewood)
I-81
PA 283
US 422
and Jake's favorite I-95 (connection under construction)

Former:
I-79
US 222
I-176

Northeast Extension:
I-78
I-80 (close - a double trumpet, but a stoplight with PA 940 in the middle!)
I-81 near W-B Scranton Airport though the two do meet at the northern terminus of the turnpike.

EDIT:
The connector between PA 283 and Harrisburg Airport also crosses over the main E-W turnpike without an interchange.

The big one in Florida is where the Turnpike goes under SR-417, Orlando's eastern beltway, without an interchange. To make a connection you have to drive a number of miles along surface streets. They have the pavement stubs for future ramps along the 417 but no current plans that I'm aware of to actually finishing it.

[1995hoo]

The three that immediately pop to my mind:

–I-295 and the New Jersey Turnpike's Pennsylvania Extension
–NJ-42 and the New Jersey Turnpike
–I-195 and I-895 in Maryland (though I should note that I-195 was built later, and I-895 is the Harbor Tunnel Thruway with no exits on the one side, and there are other expressways that provide the connections with minimal to no out-of-the-way travel)

A couple similar threads from last September.  Several of the locations already mentioned here were also mentioned in the first thread:

Thanks.  I knew they existed as I contributed to them, but I didn't know what keywords to use.

US 222 has always had an interchange with the Turnpike.  There is a picture on my US 222 page which shows the connector after it just opened, and you can see that the concrete for 222 ends just to the north of the Turnpike.

[sandwalk]

A few I can think of off the top of my head......

- Interstate 57 and Interstate 294 in the south Chicago suburbs
- Ohio Turnpike (I-80/I-90) and Interstate 475 near Toledo
- Ohio Turnpike (I-80/I-90) and Interstate 271 between Cleveland and Akron
- Ohio Turnpike (I-76) and Ohio State Route 11 Freeway near Youngstown

Maybe we should exempt toll roads from this discussion and just talk about toll-free freeways that don't connect.

[mgk920]

Maybe we should exempt toll roads from this discussion and just talk about toll-free freeways that don't connect.

I was thinking, too, that we should omit tollways and only include freeways.

There is a case in the Wheeling, WV area of two freeways overcrossing each other with no direct connection.
See:
http://maps.google.com/?ie=UTF8&ll=40.071651,-80.740607&spn=0.00954,0.021973&t=k&z=16
(east-west is I-70, north-south is OH 7)

Another one relating to the Ohio River and its tributaries, does the I-579 freeway technically extend far enough south to overcross I-376 in downtown Pittsburgh, PA?

The big one in Florida is where the Turnpike goes under SR-417, Orlando's eastern beltway...

I've often wondered why there is no interchange for that pair. Two Expressway Authorities in a pissing match, I suppose.

I've heard that I-95 and I-276 are to be connected, but haven't heard or seen anything about this, including driving through the area on both roads recently. Has construction actually started? How is this interchange going to work?

Also, I-95 does not connect to I-76 WB in Philadelphia. If you are traveling SB on I-95, you have to take I-676 (Vine St Expressway) to connect to I-76 WB. If you are traveling NB on I-95, you have to take PA-291 (George Platt Br) I believe.

And then of course there's Jersey, but there's too much to change with those freeways to go on about right now...

I-579's southern terminus is the PA 885/Boulevard of the Allies interchange, with the rest of the highway south designated SR 3069.

The only construction that has been going on are the widening of bridges along I-276 to accomodate a six-lane Turnpike to the future interchange.

[Quillz]

Not a freeway, but NIMBYs successfully prevented CA-210 and CA-83 from intersecting.

Also, doesn't really count, but CA-23 and CA-118 do not have an interchange, the freeway simply curves and continues onward as the other numbered highway. But this was because a full freeway interchange was planned at one point in time, but was never built.

Actually, after looking at your picture and Google, I'd say that the Turnpike and US 222 still don't connect in Freeway-freeway style as the connection from US 222 is a diamond interchange.

Or, I put it in the same class as I-80/476

Both pairs of highways connect, but neither has a free flowing connection between them for all movements.

Didn't the South Pasadena NIMBYs also prevent the 710 from having an interchange of any kind with the 110 if it ever gets extended?

[Quillz]

They might have, I'm not completely sure. I do know Caltrans is considering advanced tunneling techniques to send the 710 under South Pasadena, though.

[ftballfan]

Even though this is off-topic, has IDOT considered a tunnel to get IL-53 past Long Grove without routing it way out of the way? From what I have seen on here, IL-53 is widely supported in most of the rest of Lake County.

[rte66man]

I-30 and TX360 in Arlington. While I-30 used to be the DFW Turnpike, it has been a free road for decades.  Besides, there has never been a full freeway connection.  You still have to go through numerous traffic signals.

It is not a completely limited access interchange, but they still connect unlike 76 with 28, 219, 81, etc.  If this one doesn't count, then neither does the Toll I-376 interchange.

[Kacie Jane]

I would agree that neither US 222 nor the western/northern I-376 connections count as freeway-to-freeway interchanges.  They're freeway-to-connector (via 90-degree turns)-to-freeway interchanges, and certainly not what one expects when they see two blue lines crossing on the map.  (Although the I-376 connection is closer for some of the movements, at least.)

Definitely qualify for this thread.

If those qualify, then there's a very long list of others.  All of these are interchanges connecting two freeways, but they aren't free-flowing free-to-freeway interchanges.

I-35/Kansas Turnpike and US 54/US 400/Kellogg Freeway in Wichita, KS (the current configuration is only temporary, as the US 54 freeway will be extended east):

Do volleyball interchanges count?

I-380 and IA-100 (Collins Rd) meet at a volleyball interchange in Cedar Rapids. Although Collins technically isn't a freeway, it could easily become one.
