Interstate 20 (I-20) is a major thoroughfare through the central region of the US state of Mississippi. Spanning 154.5 miles (248.6 km), it connects Jackson and I-55 with Vicksburg and the Mississippi River in the west and Meridian and I-59 in the east.
Route description[]
I-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. Route 80 (US 80) alignment, except for a short bypass around Bolton.
In Jackson, I-20 briefly merges with I-55 before separating just east of the Pearl River. The old directional interchange at I-55 North and cloverleaf at US 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, I-59 joins I-20 at what is locally known as "The Split", 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.
