I-20 traverses the northern portion of the state, serving the metropolitan areas of Shreveport–Bossier City and Monroe, as well as the smaller cities of Minden and Ruston. It entirely parallels the older U.S. Highway 80 (US 80) corridor through Louisiana. The route is mirrored by I-10, which traverses the southern portion of the state. The two are connected by I-49, the state's major north–south Interstate Highway.
