[...] I betcha that the DOTD is more willing to complete I-49 North as a connector, then focusing its efforts on I-49 South. I'd prefer to see 49 completed to I-30 before anything else... anyone thought about renaming I-49 South as I-10S, and 10 thru BR as I-10N?
Ummm...I-49 North is pretty much complete and fully funded, other than the ICC segment in Shreveport between I-20 and I-220.
I-49 South's main competition for funding isn't I-49 North...it's the Baton Rouge Loop and I-69. And NO, don't bring back suffixes for Interstate highways.
When I-49 is ultimately extended to Fort Smith and the existing I-540/US 71 corridor from there through NW AR and MO is converted, the east-west segment from Lafayette to NOLA won't be as much a stuck-out thumb. So, for continunity's sake, and connecting NOLA and the South Louisiana ports to another major N/S route, I'd stay the course.
