Central Santa Rosa County is the area north of the bays and south of the extensive forests separating it from North Santa Rosa. The central section developed along the so-called Old Spanish Trail that ran from St. Augustine to New Orleans, and further points west. Today, U.S. Highway 90 closely parallels the old trail, and is the main highway that connects the region. Despite recent growth, the Central Region is best identified by its rural roots, and can be best characterized by traditional Southern culture. The Pace and Milton communities compose the Central Region, with both having populations roughly around 30,000. The county seat, Milton is located where the trail crossed the Blackwater River. To the west of Milton bordering the Escambia River, Pace has experienced exponential growth both residential and commercial. Interstate 10 also passes through this section of the county.
