Interchanges between Conventional Roads

[NE2]

Note: Expressways in Santa Clara County are considered conventional roads as they have at-grade intersections often controlled by signals and have lower speed limits (35-50 MPH).

This thread should be a showcase of all those oddball, isolated interchanges that don't involve freeways or expressways.

So what's your point?  I did note in my post that expressways in Santa Clara County are more like conventional roads than limited access freeways.  Remember, expressways and freeways are not equal nationwide.  They may be in some states but not in others (like California).

Expressways in Santa Clara County are definitely expressways in the sense that they have a mix of intersections and interchanges. In other words, they're expected to have interchanges, so listing those interchanges is pointless, even if one thinks listing interchanges on conventional roads has a point.

So you would consider Lawrence Expwy in Santa Clara county equal to the Dan Ryan Expwy in Chicago? Lawrence has signal lights at at-grade intersections while the Dan Ryan is an interstate!  I guess this really boils down to is what's VTK's definition of an "expressway".

I took 'conventional roads' to mean something that is neither and expressway nor a freeway.  Otherwise, there's nothing really exceptional about an interchange being there.

CA-152 and Casa de Fruta is a stretch...  That's like saying US-101 and any exit north of Santa Rosa pretty much.

This one confuses me every time I look at it:

The name of a road doesn't determine what its type is.  You could call I-80 'America Street', but that wouldn't make it less of a freeway.  You could call the street I live on 'Freeway 109', but that wouldn't make it one.

That varies from state-to-state or country-to-country.  In California, freeways and expressways have different legal definitions and I don't think it's legal to name a city street a "freeway" unless certain requirements are met.  Other states consider freeways and expressways the same type of road.

[kphoger]

California may consider things to be such and such, as may Europe (let's hop over to SkyscraperCity for those discussions), but web forums tend to use generally accepted U.S. terminology, by which an expressway is a four-lane highway with at least some at-grade intersections and/or entries/exits, designed for moderate- to high-speed travel.

Once again, though....this is beside the point of the thread.  Expressways and freeways are places one would expect to find interchanges.  How about examples from more minor roads?

* Page Mill Road & Alma Ave (Palo Alto)

Page Mill is an expressway here.

KP, you're half right. For instance, in Wisconsin, expressway and freeway have very specific meanings. Expressways have a mix of interchanges and at grade intersections. For example, US 12 around Madison is a freeway but US 12 near Baraboo is considered an expressway.

CA-152 and Casa de Fruta is a stretch...  That's like saying US-101 and any exit north of Santa Rosa pretty much.

Excuse me, but what do you mean by this?

Much of US-101 north of Santa Rosa isn't technically a freeway, but it has interchanges much like CA-152 does at Casa de Fruta.  I don't really consider it much of a 'conventional' road, but I'm not sure what the OP's intent of 'conventional' was.

Not quite sure about that one. The exit ramps look like they function as surface streets (complete with names!) that end at Roosevelt at RIROs.

It's an odd duck, to be sure, but I'd definitely count it.  NY 59 & NY 303 meet with similar "street-ramps".

I wouldn't even call it all that odd...there are oodles of junctions like this elsewhere downstate, on Long Island, and in the Buffalo area, just in New York alone.

Note: Expressways in Santa Clara County are considered conventional roads as they have at-grade intersections often controlled by signals and have lower speed limits (35-50 MPH).  Both routes 152 and 156 are conventional two lane highways.  Once the two routes come together, Route 152 east of the interchange is a 4-lane expressway.

Sounds like a bit of an edge case. Other factors to consider: direct private access (yes/RIRO/none), predominant guide signage type (MUTCD chapter 2D or 2E), breakdown lanes, clear zones...

Hmmm...

Direct Private Access... yes (variety of direct and RIRO)
Guide Signage Type... definitely not Chapter 2E (more like conventional road signage)
Breakdown Lanes... no
Clear Zones... no

This used to be my neck of the woods.  Geez, that was like eight years ago....I feel old....  Anyway, they certainly function as ramps.  Roosevelt and Route 59 are major highways through there, and–believe me–most traffic on those 'streets' is going between the two.
