The TN 22 freeway is planned to become Interstate 169, but that is probably a good ways off. If it does become 169, I would terminate it at the interchange where US 45E becomes TN 43.
Is the TN-22 freeway getting extended north to connect to the new I-69 alignment?

Otherwise, it wouldn't touch I-69.

By checking the map, a gap of US-51 between TN-22 and I-69 is already freeway grade, I guess the cheapest option is reconfigurating to get TN-22 as the main throughfare.

Google Maps should update its Satellite Map of the Union City area. Construction of the Union City bypass seems to only go from just north of Allie Campbell Road to an electrical substation just north of Perry Browder Road west of TN 21. Has construction started or is construction underway south and/or east of these points?

I founded by luck more recent satellite shots of Union City area.

https://satellites.pro/USA_map#36.443346,-89.033718,13

The Bing image is a nice overhead shot of the construction on both the US 51 and TN 21 interchanges.  However the Satellites Pro image is not showing me any construction at all.

Unless either (a) the TN 22 freeway is extended north to the new I-69 alignment or (b) the present interchange with US 51 is reconfigured as free-flow for WB22>NB51 and SB51>EB22, the concept of redesignation of TN 22 as an Interstate spur is right out the window.  And something tells me, with the slow pace of mainline I-69 development in the area, that such a TN 22 connection is well down the priority list at this time.   

I would second that sentiment, but what TN-22 does have going for it is that, except for the connection to I-69, the rest of it is pretty much interstate grade between US-51 and Martin. I would predict the next priority for TDOT after the Troy and Union City bypasses are built is to work with Kentucky to reconfigure the US-51/Purchase Parkway interchange at the KY/TN state line.

I'm kind of surprised that TDOT didn't upgrade and use the existing US 51 across the north side of Union City.  It just strikes me as being a duplicative waste.  Also, what are the current plans, if there are any, for tying the TN 22 freeway into this from the southeast?

Mike

The section of US-51 approaching Union city from the south is a commercial strip. The section from the Reelfoot Ave that goes around Union City probably has enough room to support and upgrade to interstate standards, but the real problem would be how to tie in a bypass of the commercial strip further south into the existing alignment. There aren't a whole lot of good options to construct an interchange to connect a new bypass to the existing road that loops around Union City, since there's quite a bit of development on either side of 51 along that loop.  Thus the decision was made to build I-69 on a new alignment further out to minimize impacts to the developed areas in and around Union City.

There's at least one way they could have pulled it off.

Wild guess -- local politics interfered with any notion of upgrading the original US 51 bypass (access and/or relocation issues), so the "outer arc" alignment that eventually prevailed came into being.  Too bad something like Adam's concept didn't make the cut; the I-69/TN 22 interchange as illustrated certainly would lend itself to potential Interstate status for the latter freeway -- not that the presently functional facility would benefit significantly by such a designation change.

Seems no one can find the original environmental studies for why they bypassed Union City completely, but from what I can recall from discussion many moons ago it had a lot to do with US-51 being a large local traffic manager.  Local hearings did not want the changes at Reelfoot Ave.  Workers who commute to the Titan plant north of town were highly resistant to 2-3 years of construction to reach work. The new Discovery Park is supposed to bring in hotel/restaurant/truck stop development along US-51 back to the future TN-22/Main Street exit. (2 hotels have already been built in fact)

As far back as 2001, the alignment had been selected:

Another trip through Union City for me and another look at the glacial pace of I-69 construction.
Since TNDOT has such crap info about this project on their website, I was surprised to see they appear to be building a huge semi-directional Y interchange where the Union City bypass returns to the existing US 51 freeway north of town.

It makes me facepalm even harder at the expense they are going through to do this new terrain segment.  Especially when the existing highway east of the curve by the tire plant would upgrade so easily.  It's like they are trying to make this take as long as possible while still technically progressing and part of that process was selecting this enormously expensive, entirely new terrain alignment.

I may be beating a dead horse, but it didn't have to be this way.  If they did something like Froggie or I proposed, at least some part of it would be open to traffic by now instead of construction entering its second decade with no benefit yet for the traveling public.

Yea, the second one is very much what I was thinking about in my reply from a couple of weeks ago.  The 'KISS' principal at work.

For better or worse, the outer arc as profiled in the aerial photos is the one that will be built; everything else is "coulda/woulda" that might have occurred had it not been for TDOT planners and, likely, promises made to Union City and the politicos representing the area.  I'll bet the old bypass gets zoned for commercial development rather quickly, including, at least on the west side where it's visible from the new bypass, some enterprises catering to I-69 traffic.  What may not be immediately apparent is the fact that Union City is only a few miles from Fulton, where the CN rail lines converge/diverge; 2 lines north to Illinois and/or St. Louis, south to Memphis, and southeast to Birmingham.  With the advent of a largely completed I-69, the region could be marketed as an efficient distribution hub, provided there's readily available and accessible properties to place warehousing facilities.  The original US 51 Union City bypass would be a very appropriate place to locate for this purpose -- a couple of blocks from I-69, close enough to the CN main line that short spurs serving those sites could easily be built (it's pretty damn flat around there!).  Wouldn't be surprised if those considerations were embedded in the decision to construct a new-terrain outer arc around the town.
