Double/Triple add-lanes (no merge)

[jakeroot]

In Richland, WA, at the WA-240/Columbia Center interchange, the right turn onto southbound Columbia Center drive from eastbound 240 is a "free" double right turn. There is no merge involved, no signal, no crosswalk...just a free double right turn.

Another example from Washington (and closer to what I'm sure is the norm for this setup)...WA-704 @ WA-7 (Mountain Hwy): https://goo.gl/NJuoHk



I'm sure more of these exist, but I'm curious if any triple lane examples do as well? They're hard to justify due to the incredible amount of traffic a single free right turn can handle just by itself, but this is North America. Surely at least one city has built a triple free right turn.

Note:

* Freeways can be involved, as long as the movement isn't freeway-to-freeway or service road-to-freeway (at most, freeway-to-service road, as above).
* Crosswalks may be involved (signalised or otherwise)
* Lanes may merge/end after the turn (the turn could be marked with those add-lane W4-3 signs)

Just gonna reply to my own thread because I find them that interesting...

Here's some more examples of what would count. Some of these seem like freeway-to-freeway but they're not. I'm really not being picky here. If the maneuver could be marked with "FREEWAY ENTRANCE" signs, it wouldn't count. That's about it. I changed the guidelines to include roundabouts. I was trying to avoid including town-center style intersections (like the big circle at N Las Vegas Blvd and 5th/Main), but I see no reason to exclude them since they're not freeway-related.

Hwy 99 at Marine Drive (Vancouver) -- trumpet off-ramps are both two lanes and have no merge: https://goo.gl/5DDpqE...



Fern St at Mt Seymour Pkwy (Vancouver) -- almost a straight movement following the Keith Road extension to the west of here: https://goo.gl/v6r3s6...

East end of the NY 7 expressway in Troy.
I-890 Exit 4 had a few of these before it was reconfigured, can't remember how many of these remain now.

Jeez, that's a lot of lanes being added and dropped! Very retro design there. Props, though: no signals. Just lots of weaving, I'm sure.

Which is why that thing was completely reconfigured in 2016-17. Got rid of that inner loop and redundant EB Exit 4B, though based on recent GSV, the 2-lane merge out of the GE plant remains.

I don't know if this one on NY 9R in Saratoga meets OP's intent, as one of the lanes immediately ends.
Couple in Buffalo at the west end of the NY 33 expressway, too.

The first thing that came to mind was the entrance to Harrisburg Area Community College, although the right lane turns into a right turn lane for the PSECU building.

That counts! Very traditional example otherwise. Nice find.

I'm not totally sure if this one counts. Of the three right turn lanes, the rightmost one is a clearly "free" movement. The middle lane has a signal, but does result in an added lane. I think the no-turn-on-red prohibition might disqualify it, though. I feel like posting it here anyway though just because of the general weirdness of this setup, particularly the very close proximity to that roundabout.

I-195 East to CR 537 West in NJ.  The 2 exit lanes from I-195 East flow straight thru onto 537 West, joining the single existing lane.  (Note, the white skip line on the ramp appears to disappear...it's there in real life as shown in this GSV: https://goo.gl/maps/My5MeLbtjQw ) The purpose is due to Six Flags Great Adventure about a mile from this location.

US 20/NY 5 at NY 332 was the first thing that came to mind. Strangely, it doesn't contribute any lanes to NY 332, because it's usually free-flowing, though stopping would be required on at least one of the four (?) signal phases.

Technically wouldn't count because there's only one free-flow right turn, but a very interesting setup nonetheless! WSDOT does something similar, on occasion: https://goo.gl/E6cXUx

Reminds me of my original post; lanes being added to a narrow road, turning it into a wide arterial.

There's also one at the Great Adventure exit: https://goo.gl/maps/b88tdeEuMcH2

I would imagine there's plenty of cars attempting an "undertake" right there (through the gore point).

Nice example, especially since no freeway is involved. I do find it odd that the maneuver has a green arrow, despite not having any conflicting movements (or even a crosswalk).

Wouldn't really count since no lanes are being added to NY-332, but I do like setups like that (where the double right turn is more of a slip lane; see here: https://goo.gl/vZYFkx).

I'm not 100% sure, but I don't think that arrow ever actually turns off.  I think it's to let drivers know that they can turn without stopping even when the signal is red for through traffic.

I don't think that would be the first example of that in Illinois. Permanently green arrows are not used in WA as far as I know, but I'm sure I've seen an example where you are. Especially since, as far as I can tell, all right turns are signalised. So there's bound to be a few of these.

Right turn movements are always included with traffic signals in Illinois--it isn't like Wisconsin or Alabama where signalized intersections have a separate yield sign for the right-turning traffic.  So if there's a free-flowing right turn at a signal in Illinois, it's a rare exception--so signal designers will include a permanently-burning green right arrow.  A 4-section head on the right will usually be an indicator of an always-permitted free right turn.  I really like this idea, since it immediately clears any confusion a driver might have about their chance to turn right.  This is a bit of a tangent, but here's another example of another Illinois permanent-burn green right arrow--it even has a one-section head with a green right arrow that never shuts off!  https://goo.gl/maps/zGJw15CP2YH2

It's hard enough to find an example in Illinois of a SINGLE lane that gets to continuously turn right, so I don't really anticipate finding any new examples of double-right turns of the same nature around here.

There are a couple examples in the I-95/US 202 interchange in Delaware

Southbound, there are two lanes that flow from a semi-SPUI from DE 141 that then merge into US 202 before merging into one and then exiting onto I-95 South.  There is a lot of weaving in this area, especially AM rush.

In the other direction, traffic from I-95 North to US 202 North merges with one lane of thru traffic from Wilmington to make three lanes of US 202 North.

Shamelessly continuing the tangent: there's an example of this with permanently-lit green straight arrows near me on US 29/78. Southwestbound traffic encounters no cross traffic here, so they can continue straight through all the time.

The tangent he was referring to was that the slip ramp was tangent to both roads, not that the road was the tangent itself.

I mean, we have a few of those too, except NY typically uses a standard 3-section signal. I've never seen this one at I-87 Exit 9 be anything other than green[/url], nor would there be a reason for it, as the signals in the area aren't preempted for emergency vehicles.

These things are still unusual enough that they catch my eye when I find one.

That is cool, but technically doesn't count since it leads to a freeway.

This is a very weird setup, especally considering that this isnt the entrance to a major waterpark nearby, this is. Best I can tell, the only things this road leads to are some big box stores, and the employee entrance to said waterpark.
