Interstate 10 (
I-10) is a part of the
Interstate Highway System that runs from
Santa Monica, California, to
Jacksonville, Florida. In
Alabama, the Interstate Highway runs from the
Mississippi state line near
Grand Bay east to the
Florida state line at the
Perdido River. I-10 is the primary east–west highway of the
Gulf Coast region of Alabama. The highway connects
Mobile, the largest city in
South Alabama, with
Pascagoula, Mississippi, to the west and
Pensacola, Florida, to the east. Within the state, the highway connects Mobile and
Mobile County with the
Baldwin County communities of
Daphne and
Fairhope. I-10 connects Mobile and Baldwin County by crossing the northern end of
Mobile Bay and the southern end of the
Mobile-Tensaw River Delta via the
George Wallace Tunnel in Mobile and the
Jubilee Parkway viaduct system between Mobile and Daphne.
