State Road 852 (SR 852), locally known as County Line Road and North 215th Street, is a 2.534 miles (4.078 km) long east–west four lane divided highway straddling the boundary between Broward and Miami-Dade counties in Florida. The western terminus is an intersection with SR 817 (West 27th Avenue in Miami-Dade County, University Drive in Broward); the eastern terminus is an intersection with US 441 (State Road 7 in Broward County, Northwest 2nd Avenue in Miami-Dade). The state road designation is omitted on many maps, but the street itself is signed by the Florida Department of Transportation.
State Road 852 begins at SR 817 at the intersection with the eastbound exit from the HEFT to SR 817, with SR 852 heading east as County Line Road as a divided four-lane highway. The westernmost mile of SR 852 is wedged between the property line of Calder Race Track and an embankment atop which the Turnpike extension is constructed. At roughly the midpoint of SR 852 is an onramp to the mainline Turnpike (SR 91). East of the Turnpike interchange, County Line Road passes through a residential area and near the eastern terminus, passes by a collection of television and radio transmission towers. State Road 852 ends at the intersection with US 441/SR 7.
Beyond the eastern terminus of State Road 852, County Line Road become an undivided two lane road as it passes through a suburban residential area until it dead ends just west of Interstate 95.
Prior to a change of designation in 1983, the same stretch of County Line Road was signed State Road 872 by FDOT (at the same time SR 852 signs lined a street that later became SR 854, also in 1983), one mile (1.6 km) to the south of County Line Road.
