I-49 currently is in Louisiana from I-10 to the south near Lafayette to the I-20 in Shreveport/Bossier city, but I'm sure the I-49 moniker extends up to Texarkana and proposal to make I-49 cross the Arkansas Ouachitas to connect with I-40 in Fort Smith or Fort Chaffee, Ark., but the I-540 crosses the Fayetteville-Rogers-Springdale area of Northwest Arkansas and the Missouri Ozarks to meet near Joplin connecting with I-44 and old route 66 in Baxter Springs, Ks. and Miami, Ok. Time to rename I-540 to I-49, but a Kansas City-Joplin interstate is a no brainer: Joplin is rebuilding from last year's F-5 tornado and I'm sure Wal-Mart in Bentonville, Ark. supports this interstate highway plan.
