Interstate 10 (I-10) a major east–west Interstate Highway in the southern areas of the United States, has a section of about 77 miles (124 km) in Mississippi.

Route description

I-10 enters the Gulf Coast area of Mississippi from Louisiana after crossing the East Pearl River. The highway parallels U.S. Route 90 to the north as it runs through the southern parts of the three southernmost counties in the state: Hancock, Harrison and Jackson.

The highway passes through the northern sections of the cities of Gulfport, Biloxi, and Moss Point.

After leaving Moss Point, I-10 heads northeastward and enters Alabama after trekking 77 miles (124 km) in the Magnolia State. I-10 contains three lanes from Bay St. Louis, Mississippi to Ocean Springs, Mississippi in both directions.


Interstate 10 was built in 1982 throughout Mississippi. Interstate 10 was originally completed in Alabama and Louisiana before Mississippi completed its portion. I-10 in Alabama routed onto U.S. Route 90 at the state line, which was the default roadway across southern Mississippi before I-10 was completed. Today, US-90 is not directly accessible from the I-10. When coming from Louisiana, I-10 ended at Mississippi Highway 607 (Exit 2). Today, entering Mississippi from Louisiana, the first twelve miles is the NASA John C. Stennis Space Center easement zone. To this day, I-10 displays the control city of Bay St. Louis from New Orleans, Louisiana and Pascagoula from traveling from Mobile, Alabama. [2]
