Editing Interstate 20 (section)

{{main|Interstate 20 in Mississippi}}

Upon entering Mississippi by crossing the [[Mississippi River]], I-20 immediately enters [[Vicksburg, Mississippi|Vicksburg]]. Between Edwards and [[Clinton, Mississippi|Clinton]], the highway mostly follows the original two-lane routing of [[U.S. Route 80|US&nbsp;80]]. In Jackson, I-20 sees a short concurrency with both [[Interstate 55|I-55]] and [[U.S. Route 49|US&nbsp;49]]. Also in Jackson is an unusually expansive [[stack interchange]], at the [[Interchange (road)|junction]] of I-20, I-55 north, and US&nbsp;49 south. The interchange replaces a former directional interchange at I-55 north and a [[cloverleaf interchange]] at US&nbsp;49. From the stack, I-20 continues eastward to [[Meridian, Mississippi|Meridian]], where it begins the nearly {{convert|160|mi|km|adj=on}} overlap with [[Interstate 59|I-59]].

The route of the Mississippi section of I-20 is defined in Mississippi Code § 65-3-3.
