So. most likely, the "Southern Loop" wil basically consist of an extension of LA 3132 to LA 1, then an upgrade of LA 1 to where I-69 is proposed to meet it, and then I-69 to I-20 near Haughton. Am I correct??
And, to answer mcdonaat, if Shreveport and/or LaDOTD wanted I-49 to be diverted via I-220/LA 3132, they would have requested it when the remaining segments of I-49 North was committed. That they haven't, and that they have proposed that I-49 be routed through I-20 rather than LA 3132 says a lot about their ultimate routing.
Sure, traffic using I-20 to I-49 coming to/from South Louisiana to/from Dallas and points west would use LA 3132, but I'm betting the farm that traffic going to downtown Shreveport and north to Texarkana, and NE from there to Little Rock and beyond would much rather take I-49 to I-20 to LA 1 to I-220 to reach I-49 North. And when the ICC is constructed, it will further diminish the need for using LA 3132/I-220, since it will allow for a much more direct N/S route. Heck, it could even relieve congestion on LA 1.
BTW...do they still refer to LA 3132 as the "Terry Bradshaw Passway"??? Or is it still most likely called "Inner Loop"??
