Florida State Road 18
State Road 18 (SR 18) is a short state road in the U.S. state of Florida. It begins in Worthington Springs in southern Union County and travels eastward for 6.60 miles (10.62 km) into Bradford County until it becomes County Road 18 at Brooker. It also has county road extensions, one of which is between Fort White and Worthington Springs, and the other between Brooker and SR 100 north of Theressa.
West of Worthington Springs, County Road 18 is a bi-county road that extends from US 27 (SR 20) in Fort White as County Road 18, also known as Southwest Fellowship Street along the O'Leno to Ichetucknee Trail. The road takes a slight curve to the northeast that ends near the intersection of County Road 131 just south of that road's own intersection with CR 238. At the west end of the short concurrency with US 41/441 (SR 25) in Mikesville, CR 18 turns north, while the trail turns south towards O'Leno State Park. Once the concurrency ends, CR 18 turns east again at the intersection of Hammock Road, and becomes Southeast Sebring Street.
