The Spaghetti Bowl – When we get into the realm of shapes and patterns that seem to be describable only by chaos theory or string theory. Spaghetti is a global phenomenon these days.
The Stack – A vertically layered arrangement of highways and connecting elevated ramps. The number of levels varies and go as high as six (though three and four are more common). Stacks are expensive to build but very efficient for high traffic volumes.
The Spooey – The Single Point Urban Interchange (or, SPUI) is very compact and one of the best choices for tight spaces in cities. Unlike the diamond, it sends all traffic through one signal. The disadvantages of this arrangement are that it can be confusing to some drivers though, and it tends to be inhospitable to bikes and pedestrians.
I see how someone could get lost and stuck on some of these, then a comment comes to mind: “Oh look kids, Big Ben!”
And I get confused at a 4-way stop.
me too Bella
There is a spaghetti stack at I-85 and I-285 Northeast of Atlanta. It can be a thrill driving 70 MPH on a ramp suspended eighty feet in the air, with somebody right in front of you and somebody else climbing up your tailpipe. My wife refuses to use the upper ramps, opting instead to go two miles out of the way.
Richard, I was gonna say that reminds me of Atlanta exactly where you described. It’s just about the only thing I remember from the only time I drove through years ago.
The funny thing is that the interchange is known to all the locals as “Spaghetti Junction.”
Richard the view from there is pretty good
