Triple "Left Turn Only" Lanes

[hm insulators]

Plenty of intersections have double "left turn only" lanes, but recently, I noticed that in Phoenix, westbound Shea Blvd. to the southbound Arizona 51 Freeway is a triple left turn only. Any of those elsewhere?

[agentsteel53]

I know I've seen them but can't think of one offhand.

however, I-805 NB offramp to Mira Mesa Blvd is a triple right.  I should know, as it is about a quarter-mile away from my work.

Here's a video with a few triple left turn only lanes.

There's one right near where I live.  It's the CA-85 southbound off-ramp to Stevens Creek Blvd.  The ramp is 4 lanes wide.  The far right lane is right-turn-only.  The others are left-turn-only although the right-most left turn lane is marked as left-or-straight.

Just remembered there's another one in San Jose at the intersection of Trimble Road and Montague Expwy.  There is a triple-left turn from west Montague to south Trimble and a triple-right turn from north Trimble to east Montague.

there are at least 2 around Jacksonville .  1 is at the I-295 NB offramp to US 17 South just north of Orange Park.  There is also one in Brunswick,GA at the US 17 intersection with the FJ Torras Causeway to St Simons Island

[jdb1234]

There are 2 I can think of in Birmingham, one is at Riverchase Parkway @ Valleydale Rd, the other is at Summitt Blvd @ US 280.

Indiana
* I-465 at US 31 (northside) - both exit ramps have triple lefts:

* WB I-465 at US 421 (that straight movement is probably of such low volume I'd count this one as only and not shared):

There are at least two here in Gaithersburg:

- MD 355 north at MD 124 (view)
- MD 124 south, turning from Midcounty Hwy onto Montgomery Village Ave (view)

I-65 at US 30 in Merrillville, Indiana

I actually started a thread about this after the city of Hampton, VA, built a pair of triple left turn lanes two years or so ago. On Armistead Avenue (VA 134) at Mercury Blvd (US 258).

[roadman65]

Northbound Florida's Turnpike at Exit 272 near Winter Garden, FL had three left turn lanes.

[WolfGuy100]

There's one here in Lexington. Man O War Boulevard have triple left turn lanes leading into US 421/25 west (known as Richmond Road) since US 421/25 have three lanes per direction

[Kacie Jane]

The ramp from I-5 southbound at SR 512 has one.  The interchange used to be a full cloverleaf, but the SB-EB movement moved to a traffic signal about a decade ago. Google Maps

I remember reading a newspaper article - probably somewhere between 2 and 5 years ago - saying that one and a then-brand new one on or near SR 410 in the Sumner/Buckley/Enumclaw area were the only ones in the state, but I don't recall exactly where that one is.

[JREwing78]

The ramp from EBD US-12/18 in Madison, WI to NBD US-51 features three left turn only lanes:

Reno, NV area:

S. Virginia St SB to S. McCarran Blvd EB
Sparks Blvd NB to Lincoln Way WB
I-80 EB off ramp to McCarran Blvd East NB - to be fair, the 3rd lane is a shared turn/thru (but that thru movement never happens)

Las Vegas, NV area:

I-15 NB ramp to Flamingo Rd WB
I-15 NB ramp to Cheyenne Ave WB (a SPUI)
Too many to list on the Las Vegas Strip (most serving entrances to Casino/Resort properties).


Las Vegas even has at least one instance of triple "Right Turn Only" lanes: US 95 South & Summerlin Pkwy East exit ramp to Rainbow Blvd SB (a wide SPUI) This one probably would have been a double right if it weren't for the configuration of connecting ramps upstream, but it is a very high volume ramp though.

Yeah, I've seen the occasional triple left and triple right (the latter at I-4 and US 27). But how about a quadruple left? Do any of those exist?

From an old MTR thread: 32nd Avenue and Astoria Boulevard North over the "the 278" in Queens. http://maps.google.com/?ll=40.770036,-73.916525&spn=0.000902,0.001829&t=h

[vdeane]

The ramp from I-490 east to NY 441 has a triple left.

[tdindy88]

Denver and Colorado Springs have a few of these if I recall, it was one in the Springs that I saw that was the first time I saw one of these on two regular streets (non-freeways.)

[codyg1985]

There is such a setup in Metairie, LA at the intersection of Clearview Pkwy and Veterans Blvd. The movement from WB Vets to SB Clearview is a triple left.

There is also a triple left in Northport, AL at the intersection of US 82 (McFarland Blvd) and US 43/AL 69 (Lurleen Wallace Blvd). The NB to WB movement is a triple left.

[Michael]

The only one I could find in CNY was at the eastern split of the NY 5/92 duplex in Fayetteville (Street View).  I'm not sure if it really counts because one movement is a hard left to Lyndon Road and the other two are a gradual left to continue on NY 5 East.

[realjd]

They just put two in here in Palm Bay. One is at the west end of Palm Bay Road (CR516), the other is at the SB Palm Bay Road exit on I-95. The one on the exit actually is set up with two left turn only lanes, a left turn/right turn option lane, and two right turn only lanes.

There is also one at 96th street and Meridian Street (U.S. 31) just south of I-465.

[nyratk1]

There's a triple left (two left turn only lanes and one shared movement) on I-495 (LIE)'s south service road heading to NB North Ocean Avenue (Suffolk CR 83) in Farmingville, NY, and also a triple left (two LTO and one shared with the straight and right movements) from the Roosevelt Field Mall to WB Old Country Road in Nassau County.

Not sure of any others on Long Island, as anything greater than double lefts is rare.

[elsmere241]

There's one near Stanton, Delaware where DE 4 eastbound turns left to multiplex with DE 7 northbound.
