Under federal law (I think it was the FAST Act), there's an exemption allowing I-69 to be signed even without a connection to the rest of the system, so long as said connection is planned to be built within 25 years.  That said, it may not apply here - OSM shows the Troy bypass as under construction as well, which would provide a freeway connection to I-155.

Well with logic like that, AR-549 between AR-22 and US-71 south of Ft. Smith could be I-49 already.  No need for Future I-** on any segment up to code.

I know the exemption was for I-69 and one other interstate, but I'm not sure if I-49 was it (I-11, maybe?).  If not, it would have to follow the existing rules, as this didn't apply to all new interstates, just the ones so designated.  And in any case, AR might not be comfortable trying to guarantee that it would be connected to the rest of the system within 25 years.

That certainly could be true, although, they are pushing to get at least 2 lanes done hopefully before my 7 year old graduates college.  I don't know that I'm comfortable saying that I'll see I-49 completed between AR-22 and I-40 before my hopefully timely demise.

Related to I-69 since it will share an alignment in the future, but can someone explain to me the first 3 mile posts if I-40 upon entering from the Hernando De Soto Bridge heading east.  I totally donít understand the 1A, 1B, 1C thing. I drove it Sunday and had never noticed it before.

There are 3 exits on mile 1. To distinguish, they are assigned different letters. Exit A, Exit B, and Exit C.

It is a tricky way to hide the fact that every bit of the I-40 mileage east of the western I-40/I-240 interchange is off.  All of I-40ís mileage east of the eastern 40/240 interchange is based on the assumption that the Overton Park section of I-40 was to be completed.  And if that were the case, then I-240ís mile 0 would have been at the 40/240 western interchange, increasing eastbound.  So since they didnít want to renumber every single exit and mile marker for almost 450 miles, they stretched out the first mile to take in both the state line mm 1 and the former beginning of I-240 mm 1 into mm 1, mm 1A, mm 1B, and mm 1C, though the actual exits increase to 1G (though Iím thinking this was always the case to alleviate confusion).  There is a missing mile marker in the vicinity of the eastern 40/240 interchange when the overall 40 mileage corrects itself back to the original (Overton Park section exists) mileage. 

The true overall mileage of I-40 in Tennessee is ~453 miles.  The last exit is numbered 451, but it is only ~1/4 mile away from the NC line.  Rerouting 40 onto the 240 northern loop added a couple of miles to the overall length.  If all of the mile markers were as they should be, that exit would have likely been 453, but they would have needed to change every single mile marker and exit number from mm 1A eastward, affecting a great majority of the stateís population, so they chose not to do this.  The introduction of the blue reference markers a little over 20 years ago brought this mileage deception out into the open.

I had a feeling it had something to do with he abandoned Overton Park section and the fact that Sam Cooper Blvd. still has exit numbers (that should have been I-40's exit numbers).  That combined with the fact that the west I-40/I-240 intersection used to be mile 0 for what was I-240 on the north side of Memphis, which is now I-40.  I love your point of putting enhanced mile markers on I-40 actually caught their lies.  Like when someone takes a screen shot of something they are working on for someone else to follow along with, and in the screen shot is all the website tabs of the naughty websites they have open!!  Doing something good showed their ass a bit more. 

I just never knew they never corrected the I-40 mileage throughout Tennessee.  I thought since the Sam Cooper debacle happed so early on, they still had time to fix it as the rest of the state wasn't so firmly planted in the exit/mile marker numbering at the time. 

Thanks for clearing that up.
