Travel directions
I-10 at the John C. Stennis Space Center.
I-10 at Gulfport.
I-10 at Pascagoula.
Interstate 10 in Louisiana comes from New Orleans and crosses the Pearl River, which forms the border between Louisiana and Mississippi. I-10 then heads east and passes not too far from the NASA John C. Stennis Space Center. The highway first leads through rural areas and past the Bay St. Louis, a bay of the Gulf of Mexico. I-10 has 2×2 lanes in western Mississippi. The highway then passes through a more urbanized area around the city of Gulfport. Here US 49 joins as the primary north-south route. I-10 has 2×3 lanes through the Gulfport region.
To the east, I-10 passes through the suburbs of the city of Biloxi. There is a lagoon between the two areas. Interstate 110 connects both parts of the coastal region. Further east, I-10 narrows again to 2×2 lanes and then crosses the swamps surrounding the Pascagoula River on a 6-kilometer bridge. Here, I-10 passes the town of Pascagoula, the last place of significance in Mississippi before reaching the Alabama border. Interstate 10 in Alabama then continues to Mobile.

History
Interstate 10 in Mississippi was built remarkably late, in both Alabama and Louisiana the highway was ready, but not in Mississippi, where the 2×2 US 90 handled east-west traffic along the Gulf of Mexico for a long time. The first part did not open until about 1970, a mere 2 miles from the Louisiana border to NASA’s John C. Stennis Space Center. The highway was then extended eastward in stages, in 1973 to Gulfport, in 1976 to halfway between Biloxi and Pascagoula, and it was not until 1982 that the final link was opened along Pascagoula to the Alabama border.

Arrange
A significant portion of I-10 has since been widened. In the early 2000s, the first section was widened to 2×3 lanes between Gulfport and Biloxi. The section between Biloxi and Ocean Springs has been widened twice in succession, to 2×3 lanes in the mid-2000s and to 2×4 lanes in 2010. Around 2002, a section near Bay St. Louis was also widened to 2×3 lanes. In 2018, a widening to 2×3 lanes was completed between Ocean Springs and Vancleave.
Traffic intensities
36,000 vehicles drive from the Louisiana border, increasing to 49,000 at Bay St. Louis and 73,000 vehicles at Gulfport. 45,000 vehicles cross the Alabama border daily.
