    Suburbia terminology: corner cul-de-sac or fan-out or what?

    Hey guys, quick question:

    We're trying to put a term on a suburbia-esque street corner that resembles a cul-de-sac. I call it a fan-out, because it's a rounded cul-de-sac like corner that bulges away from the normal turn radius, with properties fronting it forming a fan.

    Anyway, have a look at the picture and let me know what you think. Also, that curb extension with cross-walk in the picture doesn't really exist, and it's not what we're talking about here

    Thoughts?

    I've heard these referred to as eyebrows, as they are curved like eyebrows.

    Knuckle or eyebrow would be appropriate.
    I'm sorry. Is my bias showing?

    The ends can justify the means.

    Wow, thanks for the quick response. I remember knuckles now.

    Now, for an even more fun question...

    We're writing definitions for different road types and features. Does anyone have a text definition for a knuckle?

    Eyebrow is what I hear most often.

    Knuckle = Eyebrow
    Eyebrow = Knuckle

    Knuckle + Eyebrow = Black Eye

    I like yours, The One, but I found another, in case anyone's interested:

    From Riverside, California:

    Street Knuckle means the area where two streets meet in termination and
    the angle of deflection between the two centerlines of the
    streets range from 60 to 100 degrees. For reference see
    City Standard Drawing Number 104.

    Thanks, Riverside!

    We've always called them "Thumbnails" on the corner or mid block, hate them, just make one a flag lot on the corner.

    I call them illegal in our code.

    Off-topic:
    I was originaly going to make a snarky comment about calling them "bad design"

    They are terrible design, I agree. But how about this one?

    A knuckle or partial cul-de-sac is a rounded expansion of a street beyond the normal curbline, typically used at a corner or mid-block.

    Knuckles are at corners, eyebrows are along straightaways.

    My neighborhood has eyebrows and I absolutely hate them. They are a result of inflexible subdivision regs that require a certain minimum frontage. I would much rather see a standard width road with a shared driveway apron or a bunch of driveways in close proximity. These are really really ugly. At least require a landscaped island in the center if you are going to allow these monstrosities.

    Why don't you knock it off with them negative waves?
    Why don't you dig how beautiful it is out here?
    Why don't you say something righteous and hopeful for a change?

    Are you sure you're not hurt ?
    No. Just some parts wake up faster than others.
    Broke parts take a little longer, though.
