What is the plan to connect the portions of I-69 in Texas to the already signed portions of I-69 (specifically the segment south of Memphis in Mississippi, which I've seen signed)? Will 69 follow 59 all the way to Texarkana, have a concurrent segment with 30 and 40 in Arkansas and then split off and connect to the I-69/MS 304 segment in Mississippi?
For Texas, go to this link
http://www.txdot.gov/public_involvement/committees/i69/default.htm and the Interim Update Reports for the 5 Segment Committees all have maps. In Segment 1, the portion of the I-69 Corridor from Tenaha to Texarkana is commonly referred to as an "I-69 Spur" and may eventually link to Future I-49 in Texas to the northwest of Texarkana.
I'm a little lazy today & cannot provide other links, but check out
Mid-South "I-69 in LA ..." thread: first paragraph of my April 27, 2011 post has links to two maps through Louisiana & my Sept. 15, 2011 post discusses current status of section from US 171 in LA to TX state line.
Mid-South "I-69 in AR" thread: my May 8, 2011 and May 15, 2011 posts have links to maps through Arkansas.
Southeastern "I-69 in MS" thread: my June 8, 2011 post has links to a map of SIU 11 through Mississippi as well as SIU 9 through and around metro Memphis.
North of that, I guess US 51 through Tennessee and Purchase Pkwy in Kentucky? I'm just trying to determine a rout off Google maps.
This link will lead you to maps of the SIUs in Tennessee:

EDIT
Mid-South "I-69 in AR" thread: my October 9, 2011 post has a map of the I-69 Connector from the I-530 interchange in Pine Bluff to US 278 near Wilmar.
