Most of Interstate 10 in Florida travels through some of the least-populated areas in the state, much of which is forested. Consequently, I-10 west of Interstate 295 in Jacksonville has only 4 lanes. In Pensacola, an approximately 3-mile stretch of I-10 is currently being widened to 6 lanes, which will be completed in 2007. A construction project also started in Tallahassee in October 2006 to widen I-10 to six lanes.
In Jacksonville, as in Arizona, I-10 is known as Pearl Harbor Memorial Highway. Throughout much of Florida, Interstate 10 is also known as State Road 8 or State Road 8A, though it is not signed as such.
