TxDOT has updated the traffic count map with 2014 data: http://www.txdot.gov/apps/statewide_...anningMap.html

I noticed a significant drop in traffic volumes on many urban freeways in Dallas, Houston and San Antonio, in some cases 40,000 - 50,000 less than in 2013, in one case (US 75) even nearly 80,000 less than in 2013. That's a huge drop in traffic which cannot be explained by economic performance alone. Such variations could occur when a major alternate route opens to traffic, but that's not the case. It appears that either the (pre) 2013 or 2014 data is off.

The record 383,000 AADT on I-10 in western Houston is now stated as 351,000. I-610 West Loop dropped from 307,000 to 273,000. US 75 in Dallas dropped from 344,000 to 266,000. I-30 west of downtown Dallas dropped from 168,000 to 122,000. I-410 in San Antonio dropped from 263,000 to 224,000.

Maybe traffic on frontage roads used to be counted along and they stopped doing so?

It does indeed include frontage roads. Which makes the Texas traffic volumes not easily comparable to other states.

This count includes frontage roads when present.

No word on if they're excluded in 2014, but it seems a possibility.

Although California never embraced diagrammatics like most other states in the U.S., it's kind of sad to see California lose one of the few remaining ones.

But it's a circle, if you had East and West you'd take the entrance for "EAST" and then see sign "WEST" on reassurance marker
I wonder what the M25 says...

It doesn't really do directions on signs (other than The NORTH/The WEST very occasionally), but uses Gatwick, Heathrow and Stansted Airports as focal points (Dartford and Watford also join the mix, but are increasingly irrelevant as signs for Stansted increase).

Traffic reports are 'clockwise' or 'anticlock'. Mileposts/Driver Location Signs use A and B.

AASHTO held their route numbering meeting Tuesday evening. Minutes here.

Of relevance to this thread:
Arkansas I-555 extension to AR91 is approved
North Carolina Future I-36 establishment has been conditionally approved as Future I-42 (this is the Raleigh-Moorehead City corridor)
North Carolina Future I-89 establishment has been conditionally approved as Future I-87 (this is the Raleigh-Hampton Roads corridor)
Tennessee I-269 extension to I-40 has been approved
Texas I-14 establishment has been rejected due to the number (and unlike NC, TX didn't agree to an alternative number)

Some big news there:
1) AASHTO seem to care about the grid being adhered to strictly when it comes to a route where it doesn't matter that much (I-36 would have been geographically north of I-40, but the bit of I-40 it would have been north of is a N-S route) but then don't wrt point 2 which is in the same state.
2) Somehow a N-S number that is too low (yes it goes west of I-95, but for about 10% of the route!) and already in use elsewhere is fine for the E-W Raleigh-Hampton Roads corridor, as long as it isn't I-89.
3) A number written into law (I-14 was designated as the number for the Central TX Corridor by Amendment 6 of the 'FAST' act) is considered unacceptable by bureaucrats, which will no doubt lead to lawsuits!

Most rural Interstates in the South are like that. Don't think they will ever been an expansion needing that much space, just think it's the easiest way to be safe by keeping vehicles apart when land doesn't cost much.

Sure, but this stretch of I-75 is even wider than usual. It might be something to do with the drainage. I think further east there is ditch in the median to collect the excess water.

Not really. A lot of interstates have trees in the median and you can't even see one direction from the other. The picture above looks like a pretty standard spacing between carriageways.

Standard median width is 36 feet (11 meters). Here it is way more.
