Highway system

Interstate 20 (I-20) is a major thoroughfare through the central region of the U.S. state of Mississippi. Spanning 154.5 miles (248.6 km), it connects Vicksburg and the Mississippi River in the west to the state capitol of Jackson and I-55 in the center and Meridian and I-59 in the east.

Route description

Interstate 20 enters the state from Louisiana across the Mississippi River where it immediately enters the city of Vicksburg. Between Vicksburg and Jackson, I-20 enters several low-lying communities.

Between Edwards and Clinton, I-20 uses the original U.S. 80 alignment, except for a short bypass around Bolton.

In Jackson, I-20 briefly merges with Interstate 55 before separating just east of the Pearl River. The old directional interchange at I-55 North and cloverleaf at U.S. Highway 49 South have been combined / replaced with a new interchange which features both loop and/or flyover ramps, plus several C/D lanes providing direct connections for the most heavily traveled routes.

Just west of Meridian, Interstate 59 joins I-20, and the two highways run concurrently through the city and on to Birmingham, Alabama. Throughout the Mississippi portion of this concurrency, I-59's mileage takes over I-20's.

The Mississippi Department of Transportation recently announced plans to reconstruct I-20 through Vicksburg. The project includes the replacement and/or enhancement of all interchanges, additional lanes throughout the city and a new bridge to close a decades-old break in the south frontage road. Environmental studies are ongoing.
