The TN Dept of Transportation (TDOT) has a site for
Transportation Projects across the state.
I have been following that for quite a while to monitor progress on 385. It is now complete as of this past November. I use it every day for my commute.
I now am watching the progress for the new ramp at I-40 and TN Hwy 196.
Here is a link (5-mile scale) of the area:

I-69 / I-269
As I mentioned, SR-385 has been completed. It is an outer loop similar to I-240.
You'll notice on the map linked above that 385 is also labeled as I-269. You'll also notice that the stretch of I-55 in south Memphis is labeled as I-69.
The I-69 Map can be found here:

Sections 7, 8 and 9 are in TN and fall under the jurisdiction of TDOT.
Section 7 runs from Fulton, KY on the state line southwest to Dyersburg. About half of this has been completed.
Section 8 runs from Dyersburg south to Memphis/Millington at 385/269. It seems that I-69 will be built generally following a path just west of existing Highway 51.
Section 9 includes I-69 through Memphis as well as I-269 (385). I-69 will not be new road construction through Memphis. Instead it will piggy-back on I-55.
To the southeast of Collierville (south of Keogh Road and east of Progress Road) TN is currently building the I-269/385 interchange. Technically, they are extending I-269 southwest where it will cross the TN/MS state line and cross over 72. Mississippi is currently building the 269/72 overpass.
From there, I-269 will continue southwest where an interchange with 78 will be built. It will eventually turn due west and connect with the segment of I-69 running from 61 toI-55.
That will complete the I-269 loop. At that point I-269 will begin in Millington to the north of Memphis and end at 61 in Mississippi.
I-22
I-22 is basically the expansion of 78 between Memphis and Birmingham. Some of this was actual new construction while other parts were bringing 78 up to interstate standards.
Much of this work has been completed. Why has the road not yet been renamed to I-69? According to the Wikipedia article
Interstate 22:
Quote:However, according to the American Association of State Highway and Transportation Officials (AASHTO), a connection to another Interstate highway must be completed before this highway is officially designated as part of the Interstate Highway System. To be completed but under construction is an interchange with I-65 near Birmingham. An interchange to be constructed near Byhalia designated as I-269 would be the western terminus of I-22. The portion of I-269 just north of this area was completed by early 2013.
So, it seems that in order to be officially dubbed I-22, the connection to I-65 at Birmingham must be completed. The expected completion date for this segment Once that is done, I-22 will be seen on maps.
Of course, as I mentioned in the 69/269 discussion above, I-269 will connect with 78. At that time 78 will have been renamed I-22.
Whether I-22 (78 aka Lamar) ever makes it all the way to I-240 remains to be see. That part of 78/Lamar from the TN/MS state line to I-240 is highly industrialized making it difficult and costly to connect I-22 to I-240.
