Interstate 269

I am confused by I-269.

As far as I know, it is supposed to make a beltline around Memphis. It is under construction as Tennessee SR-385 north and east of Memphis. I am not sure if the Mississippi SR-304 (also signed as I-69 on maps) between Hernando and the US 61 is also part of this project, but if it is, it will be like a 70 mile partial beltway around the northern, eastern and southern side of Memphis. Are there also plans to create an I-269 in Arkansas, thus completing a beltway? If it is, it might be one of the longest beltways in the United States, and the second 3-digit to enter 3 states.

I'm also not sure how the I-69 would run through the Memphis area. Will it run along I-55 and I-240 through downtown? Or will it run along future I-269 much like I-95/I-495 around Washington? It seems quite a detour to use I-269 east of Memphis if I-69 will run along US 61 in Mississippi and US 51 in Tennessee.

I-55 > I-240 > I-40 > TN-300 > US-51 for I-69 in the Memphis area.

Only the segment of MS 304 to the east of I-55 will become I-269.  West of I-55, it's already signed as I-69 except for the westernmost mile or so to US 61 (I-69 splits off at what was MS 713).

MDOT needs to fix that dip on the I-69 eastbound bridge currently marked with the "DIP" sign, i went over it at 45 and it was scary as heck.


Chris

So it'll be like this? (my great paint.net skills  :) )

froggie

More or less, although it won't directly follow either US 61 or US 51 in the area you show.  It'll be new alignment...the alignment in Mississippi has been finalized.  While a preferred alignment has been selected in Tennessee, there isn't an easy-does-it map on the Tennessee side, but the preferred alignment will be west of and parallel to US 51.

Here's a video of I-69 North/S.R. 304 East.

So, let me see if I got this right. Is the I-269 beltway supposed to loop from Memphis into Mississippi into Arkansas then back into Memphis again?


Be well,

No. I-269 will not even enter Arkansas.

Question:

With that layout, will the new I-22 (current US-78) ever reach I-240? Or will it simply end at I-269 or follow I-269 west to I-69 or north to I-40, etc?

That stretch of US-78 looks like it'd need some major work, or be aligned elsewhere, to make I-22 continue to I-240/I-40.

That's a good question, I wondered why I-22 doesn't lead to the Nonconnah Parkway near Collierville (slightly to the north). That would make an easy way to connect to I-240.

froggie

TDOT has no plans to upgrade their portion of US 78 to freeway.

Haven't gotten an answer from MDOT about I-22's future routing, but the two popular theories going around are that it'll either A) end at I-269, or B) duplex with I-269 to end at I-55/I-69.

That would make an I-22/I-55/I-69/I-269 interchange. I'm sure one of you trivia-gurus know if a 4-interstate interchange is rare or not.  :cool:

I-44-55-64-70 in St Louis, at least after US 70 gets re-routed.  It's signed like it has all 4 freeways now, but I'm not sure I-44 officially makes it there now.  Anyone?

Ending a 2di at a 3di doesn't really make much sense to me.

Duplexing I-22 along MS 304/I-269 probably makes more sense....but how confusing would it be to have TWO interstate highways terminating at the same exact point??

I'd prefer the former as a temporary solution, with I-269 between the I-22 and I-55/I69 interchanges shielded with "TO I-22" shields. Sooner or later, they'll have to  make some form of connection with I-240, though, to make it complete....possibly to promote access to Memphis' airport. Perhaps maybe an expessway connection with existing US 78 as a stopgap until there is funding for a proper freeway upgrade??

Really depends upon the source.  Going by signage only SB I-55 overlaps with I-44.  The FHWA route log has I-55 overlapping I-44 (http://www.fhwa.dot.gov/reports/routefinder/table1.cfm), but then it seems to be somewhat error-prone for the St. Louis region (just check the IL mileage for I-70).  The EIS for the SB I-55 viaduct between that interchange and the I-44 interchange was labeled for I-44, so take your pick. 

But after I-70 gets relocated, and before the full build out of the new bridge plans, there will be a pair of three interstate interchanges, with I-44/I-55/I-64 at the west end of the PSB, and I-55/I-64/I-70 at the Tri-Level.  Though the Tri-Level could stay as a three interstate junction should the I-64 connector to the new bridge get a three digit designation.

I-54?  Am I missing something or is that a typo?

I've always thought that it would make sense to connect the NW terminus of I-269 in Tennessee with the I-55/I-555 interchange in Arkansas via a new Mississippi River bridge. This would provide Memphis with a third bridge across the Mississippi, provide a more direct route between Memphis and Jonesboro, and provide a bypass for through trucks on I-55 or I-40 or from I-69 north to I-40 west.

I-44 does NOT make it to I-64 & I-70. Signage on I-44 indicates that it ends and to continue north on I-55.


Government would be tolerable if not for politicians and bureaucrats.

According to both MoDOT and FHWA, I-44 does make it to I-64/I-70.

Depends on which signs you go by:

Two of the few correct signs if I-44 ends at I-55:

Regarding extending I-269 into Arkansas, I believe there is a semi-active study for a third Mississippi River crossing at Memphis, but I think it would be closer to downtown than the northern end of I-269.

froggie

TDOT did a bridge feasibility study back in 2006, and came up with 4 corridors for further study (on the map on the last page).  None would extend I-269 into Arkansas.  What I would consider the main frontrunner (most traffic impact, lowest cost, and lowest environmental impact) would basically be an extension of TN 300 west across the river, connecting either to the I-40/I-55 interchange in West Memphis, or to I-55 north of Marion.

This bridge idea was studied as a pilot project under the Tennessee Tollway Act.

Tolls are briefly mentioned in feasibility study mentioned in froggie's post and you can link to the TTA thread here

Looking through the bridge feasibility study, I really like the Bridge C option, as it could provide a better route for I-40 through Memphis and eliminate the turn at the western I-240 interchange.
