Lake City, where it runs east in an overlap with that route before branching off on its own in Watertown, then runs southeast towards the Union County Line. State Road 238 runs west to east in Ellisville and only exists for one and a half miles in the county, but still serves as an important route to Lake Butler in Union County. State Road 247 is a northeast to southwest road that spans from Branford in Suwannee County, and terminates at US 90 in western Lake City, just east of US 90's interchange with I-75. Railroads Columbia County has at least three existing railroad lines. The primary one is a Florida Gulf & Atlantic Railroad line formerly owned by CSX, Seaboard System Railroad, Seaboard Coastline Industries and Seaboard Air Line Railroad that served Amtrak's Sunset Limited until it was truncated to New Orleans in 2005 by Hurricane Katrina. Lake City (Amtrak station) was Columbia County's only active railroad station until that point. Until 1971, Lake City was a stop on the Louisville and Nashville and Seaboard Coast Line's Gulf Wind (New Orleans - Jacksonville). The Seaboard Air Line operated this and another passenger train in each direction through Lake City until 1966 or 1967. Another one is owned by the Georgia Southern and Florida Railway, and runs along US 41 from Lake City through Hamilton County. A third line runs along SR 100 into Union County.
