State Road 121 (SR 121) is a major state highway that runs north and south in northern Florida. The road is part of a long multi-state route that also goes through Georgia and South Carolina.
SR 121 is one of the major routes of a three-state highway 121 that totals approximately 475 miles (764 km) from Lebanon Station, Florida, toRock Hill, South Carolina.
Beginning in Lebanon Station at achannelized intersection withUS 19/US 98 andCounty Road 336 (CR 336) inLevy County, SR 121 travels throughGoethe State Forest where it turns east and intersectsCR 337. The road makes a sharp left curve to the northeast where it travels through desolate farmland; the only resemblance to a major intersection isCR 326. Within the city ofWilliston, SR 121 has aconcurrency withCR 316, until the intersection withUS 41. It then joins US 41 as CR 316 continues eastward, which then joins the east end ofUS 27 Alternate (US 27 Alt.), and then theUS 27/US 41 concurrency before breaking away to the northeast again, taking the DeSoto Trail away from US 41.
North ofCR 335, SR 121 hugs the west side of the Levy–Marion county line, but never crosses it, choosing to enterAlachua County instead. Immediately after theinterchange withInterstate 75 (I-75) at exit 382, SR 121 makes a sharp left onto Northwest 34th Street asSR 331 becomes the designation for Williston Road. As it crossesSR 24 it borders the western edge of theUniversity of Florida, passing along the34th Street Wall just before crossingSR 26A and thenSR 26. North ofUS 441, the DeSoto Trail breaks away.
Within the town ofLaCrosse, SR 121 shares a short concurrency with SR 235, then has a level crossing with the CSXBrooker Subdivision, a formerSeaboard Coast Line railroad line that leads to theCrystal River 3 Nuclear Power Plant. After the intersection withCR 236 in Santa Fe, SR 121 passes by entrances to the Santa Fe River Preserve, and then is carried along a bridge over theSanta Fe River inWorthington Springs, where it intersectsSR 18. North of CR 18, the road is carried along a bridge over the formerJacksonville and Southwestern Railroad.
Briefly traveling parallel toSR 100 in Lake Butler, it intersects SR 100 as it continues northeast. The road also runs parallel to another rail-trail along the former Jacksonville and Southwestern right-of-way inRaiford, then serves as the western terminus ofSR 16 before leaving that community. After passing by the Northeast Florida State Hospital, the road intersectsI-10 (Exit 335) andUS 90 inMacclenny close toSR 228 before crossing theGeorgia state line on its way toSouth Carolina.

The segment between US 19 and 98 in Lebanon Station and US 41 in Williston was previously designated asFlorida State Road 335, and the segment between US 27 and 41 in Williston, at what is today the south end of SR 331 was part of a southern extension of that route.[2]
State Road 23 was defined in the1945 renumbering as:
Prior to the renumbering, this had been:
At some point, SR 23 was renumbered as part of SR 121, probably to matchGeorgia State Route 121. Before that, however, SR 23 had been extended around the west side ofGainesville to end atUS 441/SR 25 atRocky Point, and the southernmost part did not become part of SR 121. It was later given to the county, and has a possibility of becoming County Road 23.[clarification needed]
TheState Road 23 designation has since been reused for a partial beltway aroundJacksonville.
In 1975, the City of Gainesville recommended a truck ban along SR 121 and established a truck route around downtown. In 1979. FDOT widened the road within the city, which included the creation of a retaining wall along the University of Florida Golf Course that has since become a target for graffiti artists. The truck ban was lifted in the early 1980s, but reestablished later in the decade after a series of fatal accidents.

 State Road 121 Truck | |
|---|---|
| Location | Gainesville |
Florida State Truck Route 121 inGainesville, Florida was formed in the mid-1970s in order to divert trucks form the congested downtown areas of Gainesville.[3] The route begins at the intersection of State Road 121,Florida State Road 331 and Alachua County Road 23, removing the concurrencies with theSR 24 and26 Truck Routes. At the intersection withU.S. Route 441, the routes are joined by a truck route of that route as well. The four truck routes run northeast along SR 331 and then curve to the north. SR 331 terminates at the east end of the overlap of SRs 20, 24, and 26, which also serves as the terminus of Florida Truck Routes 24 and 26. However US 441 Truck and Florida Truck Route 121 continue to the northeast until the intersection withFlorida State Road 222. At this point, the truck routes turn west overlapping SR 222 and intersectionFlorida State Road 20. US Truck Route 441 terminates at the intersection of SR 222 and US 441, while Florida Truck Route 121 makes a right turn and follows US 441 northbound until the intersection with its parent route.
