Locally known as Northlake Boulevard, the current edition of State Road 850 (SR 850) is a 1.2-mile-long street that forms the southern city limits of North Palm Beach and the northern city limits of Lake Park for most of its length. The road extends from an intersection with Old Dixie Highway (SR 811), through several shopping centers, to an intersection with U.S. Route 1 (SR 5).

Route description[edit]

State Road 850 begins at the intersection of State Road 811 and Northlake Boulevard, with Northlake Boulevard serving as the border between Lake Park to the south and North Palm Beach to the north. SR 850 takes Northlake Boulevard east as a six lane divided road, with shopping destinations lining both sides of the road for the brief 1.2 mile road. The road crosses a small canal halfway through the road, and it enters North Palm Beach proper 0.2 miles west of the eastern terminus at US 1.[2][3]

West of the western terminus of SR 850, Northlake Boulevard continues for 13 miles (21 km) as County Road 809A (former State Road 809A), crossing the southernmost portion of Palm Beach Gardens and the northernmost corner of West Palm Beach before terminating in an intersection with Seminole Pratt Whitney Road, in the wetlands north of Loxahatchee.[2][3]


Prior to 1980, State Road 850 was a Florida Department of Transportation designation for a stretch of Corkscrew Road in Collier County, Florida that is now County Road 850. From 1980 to 1983, State Road 850 was an FDOT designation for the road in Miami-Dade County, Florida that is now SR 932. Northlake Boulevard was given the SR 850 designation in 1983.
