Interchanges between Conventional Roads

[vtk]

Here's one I randomly discovered while looking through Google Maps: Route 79 at US 40 in Hebron, Ohio, which seems to be pretty recent - part of a bypass with just this exit, at-grades at all other junctions north and south of there:

http://maps.google.com/maps?q=E+Main+St+%26+Wooster+St,+Hebron,+OH&hl=en&ll=39.960001,-82.482412&spn=0.013141,0.019419&sll=39.961974,-82.475545&sspn=0.013141,0.019419&vpsrc=6&hnear=E+Main+St+%26+Wooster+St,+Hebron,+Licking,+Ohio+43025&t=k&z=16\

---

A couple of other NorCal examples:

- Taylor Boulevard and Pleasant Hill Road, Pleasant Hill.  This was slated to be included in the original corridor for unbuilt Route 77.

http://maps.google.com/maps?q=Pleasant+Hill+Rd+%26+Holland+Dr,+Pleasant+hill,+CA&hl=en&sll=37.923347,-122.095463&sspn=0.013524,0.019419&vpsrc=0&hnear=Pleasant+Hill+Rd+%26+Holland+Dr,+Walnut+Creek,+Contra+Costa,+California+94597&t=h&z=17

It may be short, but that bypass portion of OH 79 is definitely an expressway by Ohio standards.

In your second example, I'd say Taylor Blvd looks a bit like an expressway, particularly north of that interchange.  It doesn't seem to use Chapter 2E signage though...

Here's an example turned up by another thread: NY 15 & NY 252. NY 252 looks like a half-assed attempt at an expressway, and the interchange looks like a half-assed attempt at a SPUI.

I don't know if this technically counts but Northwest Highway (us 14) and Illinois 68 Dundee road on the western side of Palatine as your heading out of the city is an interchange.

Here's an example turned up by another thread: NY 15 & NY 252. NY 252 looks like a half-assed attempt at an expressway, and the interchange looks like a half-assed attempt at a SPUI. 

Nothing of the sort; this interchange predates SPUI nascency by decades. It's a diamond interchange with Texas U-turns, the only oddity being that the entrance ramps to NY 252 are controlled by signals. Well, that and all of the ramps have driveways intersecting them, hence the need for U-turns. Actually, when you put it that way, it's almost more like a mini-frontage road system than an interchange (although it serves that function also).

I won't disagree that Jefferson Road (as we call NY 252) here is a little half-assed, if only because the marked 45 mph speed limit is almost impossible to actually attain.

The recent widening is definitely half-assed, it would be so much better if they did 3 mainline lanes between Marketplace and Hylan Dr. The rest of the road moves well, but it is almost worse now there by leaving that one place small.

That part of the road wasn't included in the project, for whatever reason.

(I realize that's probably your point, so I'd just say that it wasn't half-assed, it was non-assed. )

One more from MN that I came across this weekend:

Jackson Street at George Street in St. Paul (the ramps are not signed for George Street at all though)

[tchafe1978]

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.
Aberg Ave. at Packers Ave.

There are several in the Milwaukee area as well, I haven't looked them all up yet, but a few off the top of my head:
Capitol Dr. (WIS 190) at WIS 74/County F
Capitol Dr. at Pilgrim Rd. has jughandle ramps
Capitol Dr. at Port Washington Rd.

Those are the ones I can remember right now, there are several along Brown Deer Rd (WIS 100), Green Bay Rd (WIS 57), Appleton Ave. (US 41), and Loomis Rd (WIS 36) but I can't remember all the exact intersections.

[codyg1985]

Here's a very compact cloverleaf at US 31 and AL 149 in Vestavia Hills, AL.

There's several at Redstone Arsenal, and one at Savannah River Site.

I believe that cloverleaf in Homewood as jdb1234 pointed out (not Vestavia Hills) is one of the oldest cloverleafs in the United States

[berberry]

Oldest in Alabama anyway, if this article is correct.  I hope you're not too attached to it because it sounds like that interchange might be going away.

AbE:  Oh yeah, check the part of the article where it says that the cloverleaf interchange has become obsolete.  Seems the highway folks are switching over to something called "ramps".

?

Nooooooo! I hope this isn't replaced.

Jackson Street at George Street in St. Paul (the ramps are not signed for George Street at all though)

Either Google's wrong in saying the two don't intersect, I'm crazy, or you're referring to Pennsylvania Ave. 

[hbelkins]

NY 78 and NY 324 near Buffalo...

9th Street and Oak Street in Louisville. It was built in 2003 as part of the 9th Street Extension project. 9th originally ended at Kentucky Street. As far as I can tell, not many people travel the new roadway, and the interchange was really not needed. A stoplight would have worked just as well.

It looks like one of the few conventional road/conventional road SPUI examples, too!

Actually I think this is Robert Street and George Street, which definitely has some weird ramp things. At least it used to.

US 158/NC 87/Business US 29 in Reidsville, NC is a weird case: at times appearing to be a conventional boulevard, but then having Super Two-like segments at key junctions.  Aptly named "Freeway Drive" -

http://maps.google.com/maps?q=Freeway+Drive+%26+Vance+Street,+reidsville,+NC&hl=en&ll=36.353327,-79.691412&spn=0.013808,0.019848&sll=36.355107,-79.690554&sspn=0.013808,0.019848&vpsrc=6&hnear=Freeway+Dr+%26+Vance+St,+Reidsville,+Rockingham,+North+Carolina+27320&t=k&z=16

Although Wendover Avenue in Greensboro is clearly a freeway west of US 220, there is one segment through the urban core that briefly contains two interchanges, before reverting to city street on either side:
http://maps.google.com/maps?q=Summit+Ave+%26+3rd+Street,+Greensboro,+NC&hl=en&ll=36.088089,-79.776621&spn=0.013855,0.019848&sll=36.08743,-79.777157&sspn=0.013924,0.019848&vpsrc=6&hnear=Summit+Ave+%26+3rd+St,+Greensboro,+Guilford,+North+Carolina+27405&t=k&z=16

Here's another Greensboro example, at Merritt Drive and Patterson Street:
http://maps.google.com/maps?q=Halifax+Road+and+Merritt+Drive,+Greensboro,+NC&hl=en&ll=36.054381,-79.853911&spn=0.00693,0.009924&sll=36.054355,-79.854662&sspn=0.00693,0.009924&vpsrc=0&hnear=Merritt+Dr+%26+Halifax+Rd,+Greensboro,+Guilford,+North+Carolina+27407&t=k&z=17

Here are two folded diamonds (well, actually three) between conventional roads, that I drive by quite often. the first one is in Hawkesbury, ON, between ON-34 and old Trans-Canada Highway 17 (now Prescott & Russell County Rd 17).

http://maps.google.com/?q=45.59629,-74.62069

Then there is Old Québec Route 9C in Châteauguay (Chemin Saint-Bernard) which used to be an important bypass (or was supposed to be one...) of the city. Parts of it have been twinned, and interchanges have been built.

http://maps.google.com/?q=45.38083,-73.75236

Actually, west of the shown area, you can see that twinning work had been done; in fact another bridge was even twinned, but the north carriageway is not open to traffic and has probably never been. I think it might be a bike trail or something now.

EDIT: Fixed "been" typo.

Was this ever planned as part of Autoroute 30?

Actually I think this is Robert Street and George Street, which definitely has some weird ramp things. At least it used to.

It is, and they still exist AFAIK.  Functionally the same thing as several locations in DC:  Dupont Circle (with Connecticut Ave NW passing underneath), Scott Circle (with 16th St NW passing underneath), Washington Circle (with K St NW/US 29 passing underneath), South Capitol St at M St SW/SE, North Capitol St at New York Ave/US 50, and North Capitol St at T St NE/NW and Rhode Island Ave/US 1.  South Capitol at Malcolm X Ave is more of a traditional tight diamond, with I-295 just to the east.

Elsewhere in DC, a partial interchange existed at New York Ave/US 50 and 9th St NE.  However, a recent bridge replacement project (shown under construction on the aerial) eliminated the direct ramps and replaced them with a connector road between New York Ave and Mt. Olivet Rd.

An elaborate mix of ramps exists between South Capitol St, Suitland Pkwy, Howard Rd SE, and Anacosita Dr SE.  If the city finds funding for their planned Frederick Douglas Bridge replacement (South Capitol over the river), this will be replaced with a traffic circle.

Speaking of Suitland Parkway, it's a limited-access route (originially built as "Military Rd", connecting the then-new Andrews AFB to central DC) with a mix of intersections and interchanges.  Interchanges exist at Alabama Ave SE, Branch Ave/MD 5, Silver Hill Rd/MD 458, Suitland Rd, and the Andrews AFB North Gate.  DC has plans for an "inside the median interchange" at Martin Luther King Ave SE.

Semi-related, there are three segments of road in DC that were originally built in the '50s intended to be freeways, but are basically classified as short expressway segments now.  These are North Capitol St between Michigan Ave and Harewood Rd, Military Rd NW between Oregon Ave NW and 14th St NW, and East Capitol St between RFK Stadium and 40th St NE.

Is the North Capitol Street expressway part of what was planned to be I-95?

Maybe in the early stages, but the final plan for I-95 followed the rail line to the east.

As NE2 says, I-95 would have passed to the east of there where the railroad tracks are. See this map on Scott Kozel's site. The segment of North Capitol Street to which froggie refers is in the upper right quarter of the map where you see a cloverleaf interchange depicted (follow the red ink down from the top and look to the left when you hit the word "Brookland").

[froggie]

It was planned as a separate route from I-95 and then I-70S (today's I-270).

Here's a better map (1966): http://bp0.blogger.com/_BZaPGsbLyHM/RjvDr1eUTmI/AAAAAAAAAFY/bxHlvCnULtU/s1600-h/1966+NCF+Title+Page+Map+cropped+1280.gif
http://wwwtripwithinthebeltway.blogspot.com/2010/12/cap-north-capitol-street.html has a couple links at the end showing that North Capitol was to be a separate connecting route, continuing north from Hawaii Avenue to near the 95-70S split.

http://wwwtripwithinthebeltway.blogspot.com/2006/11/original-northern-radials.html (1959) doesn't have a legend (perhaps tan for freeway and black for arterial?), but appears to show an intermediate loop on Military and a radial on East Capitol.
