Dixie Highway in Palm Beach and Broward counties carries two segments of the State Road 811 designation by Florida Department of Transportation, as well as the local County Road 811 in southeast Florida. The entire road comprises a section of the Dixie Highway, a National Auto Trail which eventually became a former routing of U.S. Route 1 after the route was shifted east to Federal Highway. One segment of SR 811 is in Broward County and the other is in Palm Beach County, Florida. The segments of SR 811 are supplemented by three shorter segments of CR 811, one of which is unsigned.
Atlantic Boulevard, consisting mostly of State Road 814, is a major commercial and commuter highway in northern Broward County, Florida. The 13-mile-long (21 km) divided highway extends from the Sawgrass Expressway in Coral Springs to State Road A1A in Pompano Beach. It serves as the latitudinal baseline for the street grid for the city of Pompano Beach. The portion of the boulevard west of U.S. Route 441 is locally maintained as County Road 814.
State Route 814 is a 3-mile (5 km), north–south state route in western Ohio. The entirety of SR 814 lies within Champaign County. The southern terminus of SR 814 is at U.S. Route 36 (US 36) approximately three miles (4.8 km) east of Urbana, and its northern terminus is at SR 296 about five and a half miles (8.9 km) northeast of Urbana.
