Roundabout junctions

[Chris]

You can see me negotiate a bunch of roundabouts in this video.

Taken in a new neighborhood of my city.

Here are two videos that I made of some roundabout junctions: the top video is located in Douglas County, Georgia and the bottom video is located in Southwest Atlanta.

U.S. 61 and Causeway Boulevard, one of my all time favorite interchanges

At night it's even more spectacular, all the brownish-yellow lights illuminate it like a Christmas tree.

Constructed 1959; a living symbol of Jefferson Parish: from shining and gleaming with the first suburban growth wave to the semi-dilapidated condition of today, mirroring East Jefferson's current first generation suburban decay.

Interestingly, it has never borne a name, even an official one so far as I know. Folks in New Orleans just call it "Causeway and Airline" or some such. My proposed name for it would be the "Shrewsbury Four Level." In the photo all levels - Airline Hwy. underpass, railroad, elevated roundabout, Causeway Blvd. viaduct - can be observed at once.

WSDOT has an instructional video:

I couldn't help but laugh at that video the first time I saw it.  The very fact that various transportation agencies here in the US are making instructional videos to show people how to drive roundabouts speaks loads to how many folks here just don't get roundabouts.

I always think those are an insult to my intelligence

I also hate that they slabbed the word 'modern' onto it.  I hate that word. of any usage

Years ago Andy and I decided to try out the tripod at night within the interchange:



And I totally agree with the statement you made above.

Kansas is becoming quite fond of the stupid things, much to my chagrin; KDOT loves to construct them not just at "normal" places like urban areas and near freeway interchanges but also at random highway intersections in the middle of nowhere. Imagine driving along at 65 MPH for a few dozen miles and randomly being dumped into one. Bit jarring.

Has any1 mentioned about the twin roundabout interchange on I-87 @ NY 67 in Malta, NY? On NY 67 in Malta, NY, there are about 5 roundabouts in a row! Lookee here:

Also note Googles little route shield error to the right. It is signed as a state route 9 when should be US 9!

sounds like New York

Carmel, Indiana, a northern suburb of Indianapolis, likely is the Roundabout capital of the Midwest. The city has about 50 of them installed a many interchanges and is currently upgrading Keystone Ave. (former Indiana 431) into a parkway that has the dumbell roundabout interchanges at each junction. The trend is showing up up in other Indy suburbs as well, although the most famous one is the Monument Circle in the center of downtown Indy, though that is more of a traffic circle than a roundabout.

Here's a video of how a roundabout works, presented by the Missouri Department of Transportion (MoDot).

Also, here's a brochure about roundabouts.

Thanks for the tip, I'll check them out on Google Earth. I am so used to roundabouts, I think I drove across like 15 or 20 today...

A roundabout near where i live.

Here's a roundabout junction in Santa Barbara (northbound only on the freeway), where Route 144 ends at US 101:

And a true (non-roundabout) volleyball in Calgary, AB that I went through back in 1993:

Hmmm, looks like a vollyball except with a traffic circle. It looks like it would move traffic, but who knows.

It depends where they're used and how much turning traffic there is. We have some here in the UK at the junction of major freeways and they cause havoc because the turning movements are not freeflow. Most of them have had traffic lights fitted at all the approaches but this still doesn't solve the lack of capacity. One of them now has direct connectors added for two of the movements in addition to the traffic lights but it's still plauged by heavy traffic.

The two roundabouts of Marysville:

Tulalip: Quil Ceda Boulevard at 34th Avenue
Shoulets: Shoulets Road at 51st Avenue / 108th Avenue

[Bryant5493]

Here's a better photo of the roundabout at the intersection of S.R. 5 and S.R 166, just south of Douglasville, Georgia.




Be well,

I can think of 2 roundabouts in Michigan.  One is just south of Clare, where old US-27 junctions with BUS US-127, and the other is at old US-27 and a city street by Gaylord High School.

[mgk920]

They're becoming extremely common here in Wisconsin.

Aren't there quite a few by Lambeau Field?


Be well,

[SSOWorld]

not yet I believe - but once the US 41 project is done there will be.

The first of two so far is under construction in Platteville on a new alignment to connect UW-Plateville to US 151.

[english si]

Depending how you want to count it, in my (pretty small - 17k pop) town, there's either 6, or 23. The 23 includes mini roundabouts. Of course, that's just typical suburban/semi-rural England
