the first being I-75 in Springville (Exits 296 A-B), and the other two in Five Points, north of Lake City, US 41 (Exit 301), and US 441(Exit 303). Beyond this point I-10 runs through Osceola National Forest. Interstate 75 is the southeast-to-northwest interstate highway in the county, which enters from Alachua County at bridges over the Santa Fe River. It has four interchanges in the county with US 41/441 in Ellisville (Exit 414), SR 47 (Exit 423), US 90 in Lake City (Exit 427) and I-10 in Springville (Exits 435 A-B). US 27 is another southeast-to-northwest road in southwestern Columbia County, that enters from a bridge over the Santa Fe River, runs through Fort White, and leaves at another bridge over the Ichetucknee River at Ichetucknee Springs State Park. US 41 runs north from High Springs in a concurrency with US 441 until just before it reaches Lake City, Then the two routes run parallel to each other until US 41 branches off to the northwest on its way to Hamilton County, Valdosta, Georgia, and points north. US 90 was the main west-to-east highway in the county, until it was surpassed by I-10. It enters the county from Wellborn in Suwannee County, and directly enters Lake City. East of the city, it runs along the southern edge of Osceola National Forest and serves as the address of two major prisons before crossing the Baker County Line and entering a portion of the forest itself. US 441 runs north from High Springs in a concurrency with US 41 until just before it reaches Lake City, Then the two routes run parallel to each other, but unlike US 41, US 441 stays in Columbia County and runs straight north and south until it crosses the Georgia State Line. State Road 2 is located on the far northeast corner of the county, and has no intersections whatsoever. State Road 47 is a northeast-to-southwest road that spans from Trenton in Gilchrist County to US 41 in Lake City. North of there it becomes a hidden state road along US 41 until it reaches US Truck Route 90, then turns east, only to turn north again onto US 441 where it remains for the duration until it crosses the Florida-Georgia State Line. State Road 100 runs northwest to southeast from Hamilton County in an overlap with southbound US 41, until it reaches US 90 in
