Seems pointless to give a local expressway interstate designation. It just seems like a waste to have to two long distance interstates end in the same city and combine them into one continuous line.

Except "Interstate" designations change everything from a federal funding standpoint. That is why they are prized.

Some pictures taken from this guys flickr page http://www.flickr.com/photos/zachary...7601232075684/ of Interstates in Idaho. I love Idaho's old style signs with the exit number integrated with the sign. No need for a separate exit tab, looks cool.

What's so damn great about signs with exit numbers on it??
In most european countries, exit numbers are never on a seperate sign.

If it's on a separate sign, doesn't it make it easier to change the number when an exit is added in the middle (and subsequently all exits are renumbered)?
I always thought that was the rationale.

It wouldn't matter since most (all?) states number their exits by mileage/distance and not numerically. A new exit number would simply be the nearest mileage to that exit.

Many states, including MA, measure sequentially, not by mileage. Regardless, I doubt the tab system is used for the purpose of easy changes. I think it has more to do with clarity, though the integrated signs in Idaho are refreshing.

Hmm...it's also a US highway, so it should still get federal funding. Even so, it also could have been designated an even 3-digit daughter interstate of I-70 (870 is still available in Missouri).

No, Interstate Highways are eligible for 90% federal funding, but U.S. Routes are not funded the same way I believe.

Yes, correct. Only Interstate Highways receive federal funding at that high level. US highways are are in the same category as state highways and are mostly funded by its state's funds. I believe the Interstate Highway inititive of 1956 changed this designation.

As for mileage markers on exit signs, most states do this. California was one of the last, but as I understand it, they still have not completed the process, probably due to their financial crisis.

But still why use a valuable two-digit number for a local interstate? Why not give a 3-digit number?

Well, it's not that valuable. I mean, there is no chance I-64 will be extended westward from St. Louis towards western Missouri. But I liked it better when it started in East St. Louis, IL.

Two-digit interstates are there to show significant routes for interstate travel. I-64 in Missouri doesn't comply with this, it indeed fulfills a local purpose. Through traffic on I-70 will use I-70 or I-270 anyway. It's kinda like I-97 in Maryland, I-12 in Louisiana, I-88 in New York or I-86 in Idaho. Most of them are a bit too long to be 3-digit, but don't have the prominence you'd expect from a two-digit Interstate Highway.

I-97, at 17 or so miles long, doesn't even extend out of one county. They very well could renumber it I-995 or sign it as an extension of I-83 or (much less likely) I-70.

California is sequential and I see them wherever I go pretty much. Definitely not a high priority on Caltrans' budget I'm sure.

No, California didn't have any exit numbering until 2002 (except for some stretches). California obtained a waiver in 1971 because it already had built nearly all it's current freeways when exit numbering became mandatory. In 2002 the Cal-NExUS program began to number interchanges according to the distance-based system.

The FHWA requires exclusively distance-based exit numbering, but several Northeastern states still have sequential numbering. If they adopt the MUTCD changes, they have to change to distance-based within 10 years.

It is interesting to see the metric distances on an American sign.

And I heard about that the old fonts on US traffic signs will be replaced with the Clearview font. What's up with that? Will every state replace their signs?

I think all states will replace their signs. It's called standardization. Some Interstates still have signs with non-reflective letters and small round reflectors on the lettes and numerals. But that's mostly in rural areas.

Yeah, but those Metric signs in Arizona are going away as they are being replaced with newer signage.
