Close

SR 45 begins at an intersection with US 84/SR 38 (Dunham Street) in Iron City, in Seminole County. It passes through rural areas of the county and crosses into Miller County. It enters Colquitt, passing Pleasant Hill Cemetery and curving to the northwest. The highway intersects SR 91, which begins a concurrency through town, and the two turn to the northeast. Less than 1,000 feet (300 m) later, they intersect US 27/SR 1, which join the concurrency. The four highways head east, crossing over Spring Creek into the main part of town. They pass by the Colquitt City Cemetery. Then, SR 45/SR 91 split off onto West College Street. Just under 1,000 feet (300 m) later, they meet the northern terminus of SR 45 Connector (South 1st Street). At this intersection, SR 45/SR 91 turn to the north. One block later, SR 91 heads east on Main Street, while SR 45 continues to the north. Just before leaving town, it passes Miller County High School. SR 45 heads nearly due north and gradually curves to the north-northeast before entering Early County. The road curves to the northeast and then curves back to the north. It enters Damascus, where it has a very brief concurrency with SR 200. It heads nearly due-north and curves to the north-northwest and enters Arlington. It intersects SR 216 (Newton Road), which runs concurrent with SR 45 into the main part of town. Less than 2,000 feet (610 m) later, SR 62 (Blakely Road SW). At Maxwell Street, they cross into Calhoun County. At Cedar Street, they meet the southern terminus of SR 45 Alternate/SR 45 Truck. One block later, SR 62 departs to the east-northeast on Pioneer Road. Two blocks later, SR 45 and SR 216 diverge, with SR 216 turning left onto Morgan Road NW and SR 45 traveling to the northeast on Morgan Road NE. It passes through rural areas of the county and enters Morgan, where it has a very brief concurrency with SR 37. The highway heads north, curves to the northeast, and then to the east, crossing over Ichawaynochaway Creek. It intersects the western terminus of SR 234, at which point it turns north-northeast. A little distance later, it enters Terrell County on a fairly northern routing. It intersects US 82/SR 50 (Graves Highway), west of Dawson. At this intersection, SR 50 meets its eastern terminus, and US 82/SR 45 run concurrent into town. In town, they pass Dawson Country Club and cross over Brantley Creek, before intersecting SR 520. At this intersection, US 82 heads southeast, concurrent with SR 520 east, while SR 45 departs to the north, concurrent with SR 520 west. A few blocks later, they meet the western terminus of SR 32 (East Lee Street). The two routes leave town, and SR 45 heads north-northeast. It meets the southern terminus of SR 49. The highway continues in roughly a northern routing. Then it curves to the northwest, cutting across a small portion of Webster County, before curving back to the northeast and crossing over Kinchafoonee Creek. Immediately afterward, it enters Sumter County. SR 45 continues to the northeast and enters Plains. There, it meets the northern terminus of SR 308 (Bonds Trail Road). It heads north-northwest and meets its northern terminus, an intersection with US 280/SR 27 (Church Street).^[1]
