Driving on US 19 from Monticello, Florida to Perry, Florida

US 27 leaves US 19 in Capps along with SR 20, on its way through Tallahassee. From this point on, State Road 57 is the secret designation, and the road maintains the name Florida-Georgia Parkway. After the intersection with CR 158B, US 19 encounters Interstate 10 at Exit 225 in Drifton, then an intersection with County Road 57A, and later County Road 158. The road shares a concurrency with CR 259 as it intersects US 90 (SR 10) and CR 146, but it ends just south of the intersection with CR 149 in Monticello. US 19 finally crosses the Georgia state line where SR 57 ends and Georgia SR 3 and 300 begin, the former of which is the state route for US 19 into Atlanta, while the latter of which is the state route for US 19 from there to Albany, Georgia.
