## County Road 712

County Road 712 is Midway Road, an east–west road providing one of the few access points to I-95 within the county. The western terminus is an intersection with Okeechobee Road (SR 70) west of Port St. Lucie; the eastern terminus of CR 712 is an intersection with Indian River Drive (CR 707) on the western edge of the Indian River near Indian River Estates. In addition to the communities on and near the termini of CR 712, the former State Road serves Collins Park Estates, Indian River Estates and White City.
The road was formerly designated SR 712, and was one of the first of a collection of State Roads in southern Florida that was transferred back to county control and maintenance in the late 1970s to mid-1980s. Since then, the growing population of Port St. Lucie has resulted in increased urbanization along much of the route, with Midway Road between US1 and Selvitz Road being widened from a two lane roadway to a four lane divided highway.
About 1988, after SR 712 was transferred to county control, Florida Department of Transportation designated two short spurs of the former State Road as State Road 712A (McCarty Road between CR 712 and SR 70) and State Road 712B (Seven Mile Road, also between CR 712 and SR 70). Both spurs lost their signage and their places in the road maps in the mid-to-late 1990s. Neither was subsequently given a County Road designation, although some road maps do apply these roads with a County Road designation.
