OMG! Road rage would set in before I could finish navigating that fiasco.

.i live in NC too (raleigh area)..of course i hate the roads here, thats my biggest problem of living here..but who all lives in this little state?..we should all meet sometime and talk cars.

Costs for bridges can be very high, and most cloverleafs occupy a lot of land, which can also be prohibitively expensive. I would like to go back to school and learn more about transportation engineering. We have a lot of challenges now and in this coming decade.

How ironic, I drove past that exact sign two days ago. I was on my way to take some pictures at the local taxi garage (which is located on Cedar Street)

That "continuious flow" intersection is way overly complicated, wouldn't a simple "cloverleaf" perform the same function?

Found some more links:
Here's a picture from one of those "Michigan Lefts"

Lose yourself for HOURS here!

Confused yet??

I have another abnormal setup: The SPUI (Single Point Urban Interchange)

Split-level Diamond Interchange (referred to abritrarily on one site as a "volleyball interchange."

I find it quite funny that everyone else thinks of these turns as "rare" or "exotic" becuase around here they are on pretty much every big road.

They confuse some out-of-state drivers (as if they’re not confused enough) and they make getting around town more difficult for the locals. They only allow you to turn left. If you want to simply get from one side of the highway to the other then you’re SOL. You have to drive down to the next available turning lane and hope (you picked the correct one, while you are busy trying to keep watch out for other drivers doing the same thing) it turns in front of where you wanted to go.

I can see how they help traffic, but they are just awkward.

I guess it's designed for left turning movements only, according to the wiki article posted above. It is theoretically possible to cross a road like that in this manner, but who would want to?
