Interstate 49 (I-49) is a north–south Interstate Highway with multiple segments. The original portion is entirely within Louisiana with an additional signed portion extending from I-220 in Shreveport to the Arkansas state line, three newer sections are in Arkansas, and one section in Missouri. Its southern terminus is in Lafayette, Louisiana, at I-10 while its northern terminus is in Kansas City, Missouri, at I-435 and I-470. Future plans include portions of the remaining roadway in Louisiana, Arkansas, and Texas, to link Kansas City, Missouri with New Orleans.
Interstate 69 (I-69) is an Interstate Highway in the United States currently consisting of eight unconnected segments. The longest segment runs from Evansville, Indiana, northeast to the Canadian border in Port Huron, Michigan, and includes the original continuous segment from Indianapolis, Indiana, to Port Huron of 355.8 miles (572.6 km). The remaining separated segments are variously completed and posted or not posted sections of an extension southwest to the Mexican border in Texas. Of this extension—nicknamed the NAFTA Superhighway because it would help trade with Canada and Mexico spurred by the North American Free Trade Agreement (NAFTA)—seven pieces in Laredo, Texas; Pharr, Texas; Brownsville, Texas; Corpus Christi, Texas; Houston, Texas; northwestern Mississippi; and Memphis, Tennessee, have been built or upgraded and signposted as I-69. Indiana completed the fifth segment that extends I-69 through that state in August 2024.

The proposed Interstate 69 (I-69) extension from Indianapolis southwest to Texas currently has a short piece completed in the US state of Mississippi, south of Memphis, Tennessee. The south end is an at-grade intersection with the former route of Mississippi Highway 304 (MS 304) near Tunica Resorts, where MS 713 continues west to U.S. Highway 61 (US 61), and the route continues north to the Mississippi state line. Much of the route overlaps MS 304, which intersects US 61 farther north than MS 713. MS 304 continues east from I-55, connecting to State Route 385 (SR 385) in Tennessee, forming part of the I-269 Memphis outer beltway.
Interstate 69 (I-69) is a proposed Interstate Highway that will pass through the western part of the US state of Tennessee, serving the cities of Union City, Dyersburg, and Memphis. Currently, a 21-mile (34 km) section of already-existing freeway in Memphis has been approved for the I-69 designation while another segment near Union City opened on February 21, 2024, under the temporary designation of Tennessee State Route 690. However, state officials have stated that they will not commit to finishing the interstate in their state until they receive more federal funding.

Interstate 69 (I-69) is an Interstate Highway that is in the process of being built in the U.S. state of Texas. It is part of a longer I-69 extension known as the NAFTA superhighway, that, when completed, will connect Canada to Mexico. In Texas, it will connect Tenaha and the Louisiana segment of the route through the eastern part of the state and along the Texas Gulf Coast to Victoria, where it will split into three branches: I-69E to Brownsville, I-69C to Pharr, and I-69W to Laredo. The first segment of I-69 in Texas was opened in 2011 near Corpus Christi. The American Association of State Highway and Transportation Officials (AASHTO) approved an additional 58 miles (93 km) of U.S. Highway 77 (US 77) from Brownsville to the Willacy–Kenedy county line for designation as I-69, which was to be signed as I-69E upon concurrence from the Federal Highway Administration (FHWA). FHWA approval for this segment was announced on May 29, 2013. By March 2015, a 74.9-mile (120.5 km) section of US 59 had been completed and designated as I-69 through Greater Houston. As of 2024, short segments near the southern terminuses of the three branch routes have also all been completed. These branches are planned to be connected to the rest of Interstate 69.
