A new intersection design eliminates the dreaded left turn into traffic ?

We don't have anything like this intersection in any town in So Cal, probably because it requires too much land, it isn't possible to implement this design in city.

For the highways interchange we have several levels to go from 1 highway to another in both directions.

I think the "new intersection" is too complex and requires a very large area with little benefit.

There is one of these in Cheyenne, WY. The first time I drove on it after they completed construction, it was very different, but the flow of traffic is so much better.

Looks interesting and I can kind of see how traffic would flow better. But all those diagonal crosses of traffic could also be dangerous if people run lights...

They put in one of those in a town just west of Des Moines and it opened last year. I've been through it a couple times, and quite frankly it's very simple if you just pay attention.

They have this at St. George Blvd and I-15 in St. George, UT. It is weird the first few times but it does seem to help with traffic flow.

These things look terrifying to me just based on how stupid most drivers are. Maybe they'll be good for autonomous cars.

The flyover road would have to endure two traffic lights with this design and zero with a cloverleaf.

Good if the point of the flyover is to service the interstate, lame if it's a local road to those not politically connected.

Yup, that's where I first saw these a few years back.

Agreed....looks like there are numerous traffic lights. Myself I prefer the roundabout.

They built an intersection like this in Auburn Hills last year. It's brilliant. Everyone thinks so, too. I've yet to talk to anyone whose driven through it and doesn't like it. Like the photo you posted, ours combines an interstate bridge into the intersection as well.

At least in Michigan, cloverleaf ramps are no longer being used in new construction. I can't remember the exact reason, but I believe it had to do with safety. This was like 6 years ago when I was a co-op with MDOT, so things may have changed. Cloverleaf ramps sure are fun though. drive

Not new - at least around here. Several of them have been built and as pointed out, once you get past it being new, they work very, very well. Similar to roundabouts, people freak out about something new or different, but then once it starts operating figure it out and generally like them.

The left hand turn across traffic is a huge generator of conflict points in an intersection - and this arrangement effectively fixes the issue.

The same issues inherent to any signalized intersection remain (folks can run a red at any intersection - not just these). But the left hand turn conflict being removed is a huge improvement.

An example I use frequently can be looked at here:

http://www.dot.state.mn.us/funding/projects/bloomington.html

It fit pretty much within the previous diamond interchange footprint - no additional land needed.

And to blow your mind, a light rail line runs right through the middle of this one...

Cloverleafs aren't dead for new interchanges here - but in many, many cases, there is a better solution.

Looks like it may be initially difficult to navigate while snap chatting. Who wants to deal with a new traffic pattern while trying to get that perfect fishy face selfie?

Exactly!

Looks like alot of Russian dashcam style crash videos would originate from such an intersection.
