Florida State Road 710

State Road 710 (SR 710) is a 57-mile (92 km) northwest-southeast route connecting SR 70 near Okeechobee, three miles (5 km) from the northern tip of Lake Okeechobee in south central Florida, to Old Dixie Highway (CR 811) in Riviera Beach. Most of the route is also known as Bee-Line Highway and Dr. Martin Luther King Jr. Boulevard, as it parallels the railroad tracks maintained by CSX Transportation (their Auburndale Subdivision) and used by Amtrak; and doesn’t have a turn or curve in the 48 miles (77 km) southeast of Sherman, except for a small bend northwest of North Palm Beach County General Aviation Airport. Near the middle of the highway, where Indiantown is located, the route is also known as Warfield Boulevard, named after S. Davies Warfield, the president of the Seaboard Air Line Railroad who originally built the adjacent railroad tracks.
