State Road 858 (SR 858), known locally as Hallandale Beach Boulevard, is a 5.429-mile-long (8.737 km)[1] divided highway in southern Broward County, Florida.

SR 858 takes Hallandale Beach Boulevard east into West Park as a mostly commercial road.

Between Federal Highway and the eastern terminus, the road passes through several shopping centers, crossing the Intracoastal Waterway on a drawbridge one block west of SR A1A, the eastern terminus of SR 858, one block west of the ocean and just south of Hollywood.

Miramar Parkway continues an additional 2.5 miles (4.0 km) westward, until the road ends in a residential development west of Southwest 184th Avenue.

While the land along the western two-thirds of Miramar Parkway is in the process of development as the population of southwestern Broward County has been undergoing rapid growth since the late 1980s, the neighborhoods along the eastern part (including CR 858) are now fully constructed as suburban housing, which continues along most of SR 858 west of the Dixie Highway (which had the designation of SR 5A until the 1990s).
