Stand up & be counted!

You know who you are! Don't be ashamed!

You forgot "number grid? who cares who cares?"

[dgolub]

When you say "number grid," are you talking about the numbering of, for example, interstates and US routes, or are you talking about streets in cities?

Interstates and US routes, probably.

[cjk374]

Ooops...my bad.  Yes, I am refering to the numbering of US & interstate routes.

[oscar]

For Interstates and US routes, follow with occasional exceptions as needed (and some will be). 

But for state routes, I'm cool with states like Texas that make no attempt to follow a grid, so no risk of motorist confusion from exceptions to a pattern.

I really like the grid in Indiana, because it gives you a reasonable guide to where you are, without picking up a map or GPS. Of course, there are going to be exceptions for angling highways. It would be too confusing to change numbers on those roads every time they crossed a road with a higher or lower number, just to satisfy the grid.

[hotdogPi]

I like I-238.

[dgolub]

It's OK to deviate a little bit, as in I-99.  However, putting I-3 in the Southeast is just a no-no.

Of course, there are going to be exceptions for angling highways. It would be too confusing to change numbers on those roads every time they crossed a road with a higher or lower number, just to satisfy the grid.

I wish that that principle had been followed with regard to highways like the Ohio Turnpike.  When the actual roads don't follow a grid, imposing a fictional grid on them without allowing for exceptions can be counterproductive.

Like I've been saying for a while, I think multiples of 100 would make good diagonal routes, like Florida does with its grid.

Like I've been saying for a while, I think multiples of 100 would make good diagonal routes, like Florida does with its grid.

Meaning current US 11, US 52, US 62, and US 202?

[agentsteel53]

54 can count as well, and 79 and maybe even 68 (thought 68 just needs to be sawn in half).

US-202 isn't significantly more diagonal than US-1 in that general area.  it's just an artifact of how the country in general is shaped.

[SD Mapman]

I guess I've never really had to deal with grid-breakers that much... so I don't really have a strong opinion about them.

[NE2]

Indiana used 67 as its sole original diagonal (after assigning 1-65 to north-south routes).

are there any in South Dakota?  the state's layout certainly lends itself to a grid.

[hotdogPi]

In New England, there are a few minor possible grid-breakers, but nothing too obvious:

US 44 is slightly too far north.
US 202 is too long, and goes too far away from US 2.
I-89 is partially east of I-91. (Only purists will say this breaks the grid.)

Why, yes. It's a start.

[vdeane]

I don't think diagonals need their own system; there are very few perfect diagonals, so just number the diagonal by whichever direction is longer (north-south or east-west).

It helps that I'm not a grid purist.  I just don't like routes that violate the grid in a big way for no good reason.  I-99 doesn't bother me.  That I-3 proposal in Georgia, however, does.  I-26 irks me because the route is really more north-south than east-west, not for any grid-bending qualities.  I-238 drives me nuts due to the lack of an I-38 and California declaring its routes supreme (and having a huge lack of foresight) over a federal system.  It doesn't even occur to me to take note of I-89 and I-91 crossing each other.

Check out US 42 sometime.

Yes... 36, 40, and 44 are out of alignment, there's 71 (but that's part of a multi-state route), and 50's a partial grid-breaker. Other than that, not really.
