Daily conversation: What is the worst possible answer?

^^ Hamburger = resident of Hamburg in German.

Americans when they talk about Germans: ok, imagine a Hamburger

[kphoger]

I'm actually not familiar enough with the history of the term 'hamburger roundabout' to say for certain that it originated in the US.  For all I know, it came over here from England or wherever.

I already know that.  But how in the world does it help me understand the origin of the term 'hamburger roundabout'?

If it was German in origin.

explaining rotaries with a through road to an American: ok imagine a burger

I've never heard the term, and I grew up (and learned to drive) in Massachusetts, where I know of 17 such interchanges. I always called them rotary interchanges, but that was just my term for them. I'd be surprised if DOTs call them hamburger roundabouts, or even hamburger rotaries in Massachusetts.

The thunderdome junction -- two vehicles enter, but only one leaves.

The P13. It's like a huge multi-spoke roundabout, but you can only get off at the 3rd, 7th and 11th exit.

They should install one of these at the Bullet Farm and Citadel.

The Tuba interchange. With how huge cars are getting these days, trumpets were just getting too small.

2025-08-31: What are some lesser-known types of interchanges?

The mountain interchange, a four way interchange across a 20,000 foot mountain that only allows 4 cars at a time. They are common in Alanland, not in the rest of the world though.

Diamond, so named because of how rare they are. This is the only one in Connecticut, on Route 8. I almost crashed my Saab when I realized what I was driving through. I tried to take a picture, but it came out all fuzzy.

The kind that's now more commonly called GAS or SRS:

2025-08-31: What are some lesser-known types of interchanges?

Conjunction junctions

What's their function?

Hooking up roads in phases and pauses.

Found only in Schoolhouse Rock OR. It has neither stoplights nor stop signs but it has speed bumps and ramp meters on the off ramps.

The trapdoor interchange - if you drive over part of the overpass, it drops down into a ramp to the other road below, then springs back up once it's empty. Usually the trapdoor part is painted off, but if the paint's faded, drivers are in for a surprise!

There is this one on I-95 east of Bridgeport:

And these two also on I-95 near Westbrook:

And this last one jest before entering Rhode Island:

Not so rare IMO.

The no-way stop. They used to be common in Massachusetts when I was young, but they heedlessly destroyed them all by putting up stop signs and traffic lights.

At this time purely theoretical, but when flying cars become a reality, the Sphereabout will become commonplace.
