Interchanges between Conventional Roads

[colinstu]

Here's my contribution. (Milwaukee!)

http://goo.gl/maps/AFzn Forest Home Ave and how it interacts with 76TH ST and Layton Ave...and (I894/I43 too).

http://goo.gl/maps/0u3P WI-145 has a bunch of stuff. Interchange with Good Hope Rd, 107th St, 91St st, Silver Spring Dr, 76th st, and some other partial access stuff. Was supposed to be a corridor out of Milwaukee... hasn't really taken off.

http://goo.gl/maps/0dlA Miller Park Way (WI-341) and Frederick Miller Way (Canal St kind of). Here purely to move big traffic in and out of the parking lots.

http://goo.gl/maps/k2B5 Silver Spring Dr + Green Bay Ave
http://goo.gl/maps/9cLM Silver Spring Dr + Teutonia Ave
http://goo.gl/maps/j0Qb Silver Spring Dr + Sherman Blvd (Cloverleaf! damn I didn't even know this existed!)
http://goo.gl/maps/Jkku Silver Spring Dr + 76TH ST
http://goo.gl/maps/rHQW Silver Spring Dr + Appleton Ave

http://goo.gl/maps/3MFu Capitol Dr + Port Washington Rd
http://goo.gl/maps/GZwT Capitol Dr + Pilgrim Rd
http://goo.gl/maps/DAkv Capitol Dr + Redford Blvd / CH F
http://goo.gl/maps/yfQI Capitol Dr + WI-16 (WI-16 is pretty highway-ish so I won't include anymore of it)

Well that's all that I'm pretty much aware of / can find.

I've driven around the burbs of Chicago too... I know a bunch of shit exists there... and I'm sure it's already been linked.

EDIT: Found another. http://goo.gl/maps/I0UG Brown Deer Rd + Green Bay Rd

One I had completely forgotten about, even though i drove through it last year. IN 37 and IN 64 at English.

A couple I'm surprised have not been mentioned yet:

University Drive (US 72) @ Sparkman Drive in Huntsville:

I wouldn't really count that stretch of WI 145 for this example, as WI 145 is a freeway for that stretch. Also, your WI 16-WI 190/Capitol Dr. example doesn't really count, as WI 16 also is a freeway in that area. Otherwise, great finds.

I also found that you missed another example nearby to one you gave, at Brown Deer Rd. and N. 76th St.

Boulevard Pie-IX (Highway 125) and Boulevard Henri-Bourrassa in Montréal-Nord.

https://maps.google.ca/maps?q=Boulevard+Pie-IX+%26+Boulevard+Henri-Bourrassa,+Montr%C3%A9al-Nord,+QC&hl=fr&ie=UTF8&sll=49.891235,-97.15369&sspn=29.326445,79.189453&hnear=Boulevard+Henri-Bourassa+Est+%26+Boulevard+Pie-IX,+Montr%C3%A9al-Nord,+Communaut%C3%A9-Urbaine-de-Montr%C3%A9al,+Qu%C3%A9bec&t=m&z=16

It will be torn down very soon and converted into a signal-controlled intersection. Many factors are causing this, including the new toll bridge on A-25 (drivers were previously routed to the bridge on Pie-IX), NIMBY residents and traffic calming measures.

Had forgotten about this one until I crossed it this afternoon.

US 68 and OH 350 near Cuba, south of Wilimington:

[roadman65]

How about the current Huey P. Long Bridge northern approach with Jefferson Highway near New Orleans?  Right now it is a complete intersection, but it was and will be again an interchange when the new bridge gets done.  It used to  be Jefferson Highway over Clearview Parkway and the northern bridge approach, it will be the other way around once this project gets completed.  Neither roads are freeways, but some may argue that the HPL Bridge itself is a freeway, but it has surface arterials on both ends, so technically its a freeway by coincidence cause the bridge cannot be at grade with other roads.

Hmmm, get people to use the toll bridge by making the existing route less attractive

Here's another one.

http://goo.gl/maps/IUgd State Street and Hawley Road.

This is pretty much only here because State St is in a valley, but hey they're both "only" roads.

Might be stretching the definition a bit, but University Ave @ Old Middleton Rd, 1/2 diamond in Madison, WI.

There are a few in Madison, WI:
Campus Drive at Highland Ave. is a half diamond
Stoughton Rd. (US 51) at Cottage Grove Rd.
Stoughton Rd. at Milwaukee St.

I wouldn't really count those. Campus Dr is an expressway, bypassing the older residential portions of University Ave. Stoughton Rd/US 51 for the most part an expressway thru Madison/Blooming Grove/Monona. Between the interchange with WIS 30 and the signals at Buckeye Rd, the two you list are the only access points along a stretch with a posted speeds of 45-55.

All the ones with Sunrise Highway were for a potential upgrade of Sunrise into a limited-access highway, and anything east of NY 109 doesn't count for this thread. The same goes for Conduit Avenue/Boulevard, which was supposed to be upgraded into part of the Bushwick Expressway. I'm not entirely sure that this was proposed for NY 25 though.

Did anybody mention Horse Block Road(Suffolk CR 16) and Long Island Avenue in Medford, New York? Well, I'm mentioning it now.

[roadman65]

Valatie, NY has both US 9 and NY 9H interchanging there.  I do not know if someone mentioned it already, but this one flips the bill for this topic.

[amroad17]

US 20 and NY 19 south of LeRoy, NY.  With a rail line paralleling NY 19 on the west side, all traffic exits/enters on the east side.  There is a road that intersects in the southeast quadrant and there are driveways in the northeast quadrant.

[bdmoss88]

In Alabama, US80 has interchanges with AL5 and AL17. Both in the middle of nowhere and I'm not sure why they exist. Also I'm not sure the one at US43 and AL24 in Russellville is entirely necessary.

[mcdonaat]

In Louisiana, US 171 interchanges with US 190/LA 12, although the low traffic on both roads would be better served by a light. http://goo.gl/maps/SUjg2

There's a railroad there too...

There is a railroad right there. However, moving the road slightly to the north negates any need for a full interchange.

But there's still need for a bridge over the railroad. So why not take advantage of it?

It isn't on the map yet, but there's an interchange being built at US 285 and FM 1776 in Texas.  These are two very lightly-traveled roads in the middle of nowhere.  The highest traffic count is 1,300 vehicles per day on 285 south.  1776 traffic counts under 600.

Both roads have 75 mph speed limits.  It was converted to a four-way stop as an intermediate measure because of very severe accidents.  For some reason drivers on 1776 have been frequently running the stop sign at full highway speed for years.

In Nebraska:
Dodge Street (US 6) has an interchange with Saddle Creek Road, although that may be based on topography.  OTOH, there are a number of turn-right-to-go-left situations on Dodge which have nothing to do with topography, like going west at 33rd Street, 42nd Street and at UNO (University of Nebraska at Omaha).  Eastbound Dodge gets one at Happy Hollow.  Saddle Creek gets one going north at 50th Street.

For some reason unexplained to me, NE 92 at Yutan in Saunders County has an at-grade interchange at Yutan.

In Iowa:
I vaguely recall there being one in the northern part of the Des Moines area.  I think it is on Merle Hay north of I-80, but can't remember the cross road.

Sioux City  has a number on Business US 75, including one with Business US 20.  There's also one with Floyd Blvd and Transit Ave on Business US 75.

I think the one on US 59 and Iowa 92 by Carson was missed previously.

In Kansas:
I think US 24 and Topeka Blvd was not mentioned.  It persists in being a cloverleaf interchange in spite of itself.  I'm not sure if US 24 is supposed to be a freeway, expressway, or just a surface road in Topeka.

North Texas has them all over the place.

US 380 and SH 289 at the north end of Frisco: http://maps.google.com/maps?hl=en&ll=33.218997,-96.801733&spn=0.002293,0.004823&t=h&z=18

SH 56 and FM 1417 in Sherman: http://maps.google.com/maps?hl=en&ll=33.627913,-96.64513&spn=0.004565,0.009645&t=h&z=17

And farther south in Plano, a phantom one where the exit ramps were constructed but the main flyover never was: http://maps.google.com/maps?hl=en&ll=33.016383,-96.79499&spn=0.004597,0.009645&t=h&z=17

[cwm1276]

Illinois 2 and Springcreek/Auburns Streets
and
Illinois 2 and Whitman

The Whitman interchange is being discussed to become a regular intersection

[hobsini2]

A new one has been just finished this month in Downers Grove IL between Belmont Rd and Burlington Ave/Warren Ave. This had previously been a signal with a railroad crossing just south of the intersection. When IDOT built the underpass for the railroad, they also made Burlington/Warren an underpass.
